GMEOW — Global Metadata and Entity Ontology for the Web — SKOS extract
Aboutness Mode
The rhetorical relation between an information carrier and its subject matter — whether the carrier describes the subject (mention: reporting, quoting, depicting, analyzing) or enacts it (use: performing, demanding, exemplifying, embodying). A value vocabulary of individuals (never subclasses). Orthogonal to granularity, determinacy, sensitivity, confidence, and standpoint modality (Principle 9): a carrier may describe one subject while enacting another, and distinct vantages may classify the same carrier differently through the statement layer. The distinction every rubric, citation, and evidence assessment eventually needs: text ABOUT deception is not text THAT deceives.
Accessibility Assertion
A reified claim that a location or connection has a positive accessibility feature, a barrier, or a limited status for a given facet. Bears provenance (vantage, confidence, temporal scope) and suppression (displayable false — Principle 10). The flat shortcuts are gmeow:hasAccessibilityFeature and gmeow:hasBarrier; promote to AccessibilityAssertion when the claim itself must be a node.
Accessibility Facet
The dimension of accessibility being asserted — wheelchair, step-free, visual, auditory, cognitive, clearance, life-support. An open value vocabulary (individuals, never subclasses) per Principle 9.
Accessibility Polarity
The polarity of an accessibility assertion — feature (positive), barrier (negative), or limited (partial).
Account Status
The usage status of an account from its holder's standpoint — a VALUE vocabulary (active, dormant, historical, …); open set.
Acquaintance Relationship
An interpersonal relationship of social acquaintance — agents who have met and know one another (the reified form of hasMet).
Activity
Something that occurs over a period of time and acts upon or with entities — creating, transforming, using, or attributing them. The provenance-layer specialization of gmeow:Event: the occurrent that gmeow:wasGeneratedBy points to and that gmeow:wasAssociatedWith ties to its performing agent.
Address Tenure
The reified, time-scoped fact that an agent held a contact point (e.g. an email address) over a particular interval.
Adoptive Parent-Child
A parent-child relationship established by adoption.
Aesthetic Quality
A qualitative aesthetic reading — an OPEN vocabulary seeded with elegance, sublimity, kitsch. No AestheticQuality hierarchy exists or ever will (Principle 9): aesthetic traditions disagree about the inventory, and that disagreement is data.
Agent
An entity that can act, bear responsibility, and enter into agreements: a person, an organization, or a software agent.
Aggregation Function
The kind of statistical aggregation applied to a spatial region — a value vocabulary (individuals, never subclasses).
Agreement
A mutual understanding between two or more agents that creates obligations or rights, reified as a relator connecting its parties.
Agreement Name
An appellation borne by an agreement — a formal title, short name, or multilingual version of a contract or legal instrument. Carries its own gmeow:nameLanguage and gmeow:nameScript so co-equal multilingual names are separate first-class objects.
Analogy
A reified analogical mapping — the source-to-target structure-mapping (Gentner) that warrants an analogical inference: it mediates a source domain (gmeow:analogicalSource), a target domain (gmeow:analogicalTarget), and the element-pair correspondences (gmeow:hasCorrespondence) holding between them, scored by structural consistency (gmeow:systematicity, solver-layer). The warrant of an analogical gmeow:InferenceCommitment points at an Analogy. Rival mappings compete; best-analogy selection is solver-layer like IBE, never an asserted isBest bit.
Analysis Property
An open value vocabulary of analytical dimensions. Never subclassed (Principle 9).
Annotation
A reified binding of a body to a target with a motivation — the W3C Web Annotation idiom expressed as a gufo:Relator. Mediates annotationBody (the note or literal), annotationTarget (the annotated entity), and annotationMotivation (the purpose). A highlight is an Annotation with a target span but no body; a bookmark is an Annotation motivated by bookmarking. Standpoint, confidence, and suppression are carried by the relator's provenance layer (accordingTo, displayable) or by RDF-star annotations on the shortcut.
Annotation Motivation
The purpose for which an annotation is created — a VALUE vocabulary (individuals, never subclasses) aligned to the W3C Web Annotation motivation set. Co-equal: no motivation is primary or default. The set is open.
Appellation
A name as an information object borne by an entity — a person's name, a filename, a place name, an organization name. It carries the surface form (gmeow:fullName) and the structured parts (gmeow:hasNamePart); who uses it, toward whom, in what register and over what period is carried by gmeow:NameUsage. The universal superclass reconciling the scattered naming terms. Multiple appellations on one entity are CO-EQUAL — none is canonical or 'primary'.
Appraisal
An affective or aesthetic reading of something, as an observation: vantage = the appraiser. Dimensional (PAD: a valence/arousal/dominance value) or qualitative (an aesthetic quality: elegance, sublimity, kitsch) — at least one of the two forms (SHACL). Two critics disagreeing are two coexisting cells; self-report is top authority for the subject's own standpoint (Principle 9, the facetVantage precedent).
Appraisal Dimension
A dimensional axis of affective appraisal — an OPEN vocabulary seeded with the PAD triad: valence (pleasant ↔ unpleasant), arousal (activated ↔ calm), dominance (in control ↔ controlled).
Arc Sample
One reading of a character's state at a narrative position — an observation: vantage = the analyzing model or critic, subject = the frame-scoped character, position = a NarrativePosition (narrative-position axis; discourse-time by default, story-time samples legal and distinct), state = an emotion-type or analogous value by IRI (the affect slice's EmotionType when loaded, EmotionML category IRIs otherwise — soft reference, never dependency). Two analyzers disagreeing about chapter 31 are two coexisting cells (Principle 9). The existing gmeow:CharacterArc is the integrating whole: samples attach via gmeow:arcSample ⊑ gmeow:hasPart, and an arc with no samples stays valid (book-level-only analyses).
Arc Type
The interpretive type of a character arc — a VALUE vocabulary (individuals, never subclasses). Coming-of-age, redemption, and fall are examples; the set is open.
Archaeological Find Context
A reified find context binding a physical carrier to its stratigraphic unit, find-spot, excavation or documentation event, and dating evidence. A single carrier may have multiple coexisting context claims from different excavation campaigns or analytical standpoints (Principle 9). Follows the universal Observation + Relator pattern.
Article
A written work published in a periodical, blog, or scholarly venue. A specialization of gmeow:Work.
Articulation Kind
An articulation or attack quality applied to a ToneEvent — staccato, legato, tenuto, accent, marcato, pizzicato, harmonic, etc. A value vocabulary of individuals; never subclassed (Principle 9).
Assessment
An observation that scores a target against a criterion (or whole rubric) — vantage = the judge, human or model: an LLM judge is just a vantage, and two models disagreeing are two coexisting cells with no winner (Principle 9). The judge model's identity and prompt digest travel as observation provenance. gmeow:assessmentCriterion / gmeow:assessmentRubric play the observationMethod ROLE but are deliberately not subproperties of it (observationMethod is functional with a QualityValue range; Criterion and Rubric are Entities — the claimModality axiom pattern). Scoring-density expectations by target granularity reuse kernel gmeow:hasGranularity on the target.
Asset
A financial asset — a stock, bond, cryptocurrency, real estate holding, commodity, or other instrument of value. The thing that is held, not the holding itself (which is a Holding relator).
Asset Type
The kind of a financial asset — a VALUE, never an Asset subclass. Open vocabulary.
Atomic Constraint
A single ODRL constraint comparison: a gmeow:leftOperand (the dimension tested), a gmeow:constraintOperator (the comparison), and a gmeow:rightOperand (the value). E.g. leftOperand dateTime, operator lteq, rightOperand 2030-01-01 — 'valid until 2030'.
Attachment
A non-inline body part presented as an attached file. An attachment may also be a gmeow:Document or gmeow:MediaObject (the two are not disjoint), and its text extraction or summary is a derived object linked by gmeow:wasDerivedFrom.
Attestation
A reified assertion envelope that an attester vouches for a claim, artifact, identity binding, process, quality report, or ledger claim under a specific policy. Mediates between an attester, an attested subject, and optionally an attested claim or artifact. Distinct from Observation: an attestation is a vouching act, not a measurement or sensory reading. Its validity window is carried with gmeow:validFrom/validUntil; revocation sets validUntil (Principle 10).
Attestation Artifact
A concrete carrier of an attestation — in-toto JSON, SLSA provenance, W3C Verifiable Credential, DSSE envelope, C2PA manifest, EAT token, signed RDF graph, SCITT signed statement, nanopublication, signed git tag, release manifest, or signed blockchain payload. The artifact is the serialization; the Attestation is the logical vouching act that the artifact carries.
Attestation Policy
The policy or framework under which an attestation was issued — a value vocabulary (individuals, never subclasses). Open-ended; specific policies are minted as needed.
Attestation Type
The kind of attestation being made — a value vocabulary (individuals, never subclasses). Distinguishes SLSA provenance, in-toto attestation, VC, DSSE envelope, C2PA manifest, EAT token, signed RDF, SCITT statement, nanopublication, blockchain claim, git signed tag, release manifest, quality report attestation, and AI output attestation.
Authentication Result
The outcome of an email authentication check (RFC 8601 Authentication-Results) — a method (DKIM, SPF, DMARC, ARC), a verdict, and the verifying server.
Author Identity
A recorded author or committer string in a version-control commit — the raw git bytes (Name <email>). This is the immutable historical assertion, independent of the current canonical agent. Superseded identities are retained with gmeow:displayable false rather than deleted (Principle 10).
Authority Level
The claimed authority grade of a norm within its issuing system — an ordered value vocabulary (absolute ≻ high ≻ medium ≻ conditional), the kernel GranularityLevel pattern. The ordering is carried by gmeow:strongerThan on the LEVELS; what the ordering does to conflicting norms is solver work over recorded precedence claims, never a reasoner entailment (Principle 12).
Availability
A time-scoped statement of an agent's availability over an interval — free, busy, tentative, or out-of-office. The free-busy spine of the calendar layer.
Availability Status
The availability state of an agent over a time slot — a VALUE vocabulary aligned to iCalendar VFREEBUSY, never a subclass.
Awareness Level
The graded level of arousal or vigilance — how alert the experiencer is, on an ordinal ladder from hyperalert down to unresponsive. A value vocabulary (individuals, never subclasses) of six rungs (gmeow:levelHyperalert … gmeow:levelUnresponsive), each carrying an integer gmeow:levelRank (5 high → 0 low) for ordering. The named, ordinal companion of the continuous gmeow:awarenessScalar; distinct from gmeow:AwarenessMode, which names the qualitative STATE rather than its arousal intensity.
Awareness Mode
The named operational state of the experiencer — the qualitative mode of consciousness or processing an agent is in: waking, drowsy, asleep, dreaming, focused, flow, meditative, sedated, comatose (the human modes), or online-inference, offline-replay, training, sampling, dormant (the machine modes). A closed-but-open value vocabulary (individuals, never subclasses): new modes are minted as gmeow:AwarenessMode individuals. The human and machine modes coexist as SIBLINGS in one vocabulary — the machine modes are the analogues of waking / dreaming / focused / drowsy bridged by analogy, NOT by equivalence (Principle 5). The state-of-the-experiencer axis, orthogonal to content (WHAT is entertained) and attitude (HOW it is held).
Awareness Tenure
A reified situation of an agent BEING IN a given awareness mode OVER a bounded interval — a sleep episode, a focus or meditation session, a machine serving window or training run. Specialises gmeow:TimeScopedRelation (temporal slice): the awareness state holds only across the span it scopes. It carries the experiencer (gmeow:awarenessSubject → gmeow:Agent), the state (gmeow:awarenessMode), the span (gmeow:duringInterval → gmeow:TimeInterval), and the optional arousal (gmeow:awarenessLevel and/or gmeow:awarenessScalar). Tenures may nest — a gmeow:modeREM sub-tenure within a night's gmeow:modeAsleep tenure.
Axis
A coordinate axis or dimension of a reference frame (e.g. X, Y, Z, latitude, longitude, elevation, time).
Biological Parent-Child
A parent-child relationship by biological descent.
Biological Sequence Location
A sequence-level container locus — a chromosome, contig, scaffold, or the sequence itself — that hosts SequenceFeature annotations via gmeow:hasSequenceFeature. The features themselves (genes, exons, SNPs, etc.) are SequenceFeature instances with their own coordinates and types; they are not BiologicalSequenceLocation instances.
Blob
A content-addressed blob of raw file content — the leaf of a Merkle source tree, independent of filename or path. Aligned to git blob objects and Software Heritage Content by reference. A Blob is the bytes only; the name is carried by the TreeEntry that points to it.
Block
A block of transactions on a distributed ledger or blockchain.
Blockchain Account
An address-controlled account on a blockchain or distributed ledger — the entity that holds assets, signs transactions, or controls a smart contract. Aligns to CAIP-10 account identifiers and did:pkh.
Blockchain Network
A blockchain network identified by a chain identifier (e.g. CAIP-2 chainId).
Body Part
A MIME part of a message's body, with a media type and content.
Body Value
A decoded body-content object stored as a separate information object, typically the result of extracting or decoding a MIME BodyPart. Linked to its source BodyPart by gmeow:wasDerivedFrom; not a literal property on the part.
Book Release
A concrete published edition or release of a book — an out-of-universe information object and rights-bearing publication artifact. A specialization of gmeow:Manifestation. Distinct from the in-universe narrative frame it contributes to; linked via gmeow:sourceFor.
Bookmark
An annotation that records a target resource for later retrieval, motivated by bookmarking. Typically has no body and no selector (the target entity itself is the bookmarked resource).
Branch
A mutable pointer to a line of development in a repository — a named reference that advances as new commits are added. An InformationObject, not an Event or Entity.
Branch Condition Type
The kind of guard condition on a control-flow edge — a VALUE, never a subclass. Evaluated solver-side (Principle 12). The set is open; new condition kinds are fresh individuals.
Build Activity
A software build process that transforms source code into one or more distribution artifacts. The build activity consumes a commit or repository and produces a concrete distribution (tarball, wheel, binary, container image). Aligned to SLSA provenance buildType and PROV-O Activity by reference.
Builder
The build system or agent that performs a BuildActivity — e.g. GitHub Actions, GitLab CI, Jenkins, Buildkite, or a local make invocation. A SoftwareAgent scoped to the build role.
Cadastral Reference
A structured identifier for a land-administration record — a parcel number, folio identifier, title number, lot reference, or survey plan reference issued by a cadastral registry. Carries the reference value, its type, the issuing authority, and the jurisdiction under which it is valid. Temporal validity (re-survey, re-numbering) is carried with validFrom / validUntil on the reference itself.
Cadastral Reference Type
The kind of a cadastral reference (parcel identifier, folio number, title number, lot number, survey plan reference, etc.). A value, not a subclass: the set is open-ended and they share all of CadastralReference's structure, so a new kind is a new individual, not a new class (Principle 9).
Calendar
A CalDAV-style collection of scheduled events — an information object that aggregates calendar members and carries a default time zone. The container, not the contents.
Calendar Method
The iCalendar METHOD of a calendar component carried by an email — a VALUE vocabulary (individuals, never subclasses). Aligned to RFC 5546/iTIP: REQUEST, REPLY, CANCEL, PUBLISH, COUNTER, DECLINECOUNTER, ADD, REFRESH.
Calendar System
The rules mapping a time scale to human-readable dates. Co-equal: Gregorian is one peer among Julian, Hebrew, Islamic, Chinese, Persian, Ethiopian, Coptic, ISO week, and others (Principle 9).
Calibration Status
The qualitative fit between an agent's avowed confidence and its actual accuracy — a closed value vocabulary: gmeow:wellCalibrated (confidence tracks accuracy), gmeow:overconfident (confidence exceeds accuracy — the Dunning–Kruger pole), and gmeow:underconfident (accuracy exceeds confidence — the impostor pole). Its members are individuals, never subclasses. The numeric magnitude of the gap is the solver-layer gmeow:calibrationError; this is the qualitative reading.
Capacity
A measurement of the maximum number of entities a location can hold. The location is the observedFeature; the result is a ScalarQuantity. The entity kind being counted is implicit from the location's placeType and the ScalarQuantity's hasUnit (P11). A contested capacity (e.g., fire code vs. venue claim) is modelled as multiple co-existing Capacity measurements, each standpoint-indexed and confidence-weighted, never collapsing to a single winner (P9). A superseded capacity (e.g., after renovation) is suppressed via displayable false, never deleted (P10).
Carrier Medium
The medium of a physical carrier — a VALUE vocabulary (individuals, never subclasses). Print, e-ink file, optical disc, and server object are examples; the set is open.
Cascade
A NAMED chain of causal links — 'Trust Collapse: betrayal dissolves the bond, bond dissolution kills the will to survive.' A social object: the cascade exists as a recognized failure narrative, independent of anything ever occurring. Entered at gmeow:cascadeFirstLink, walked by gmeow:linkNext, graded by gmeow:cascadeSeverity. Acyclic within itself (SHACL); propagation arithmetic is solver work (Principle 12).
Causal Link
A reified type-level causal claim — antecedent kind × consequent kind × modality, with optional mechanism prose and solver-input strength. Mint one when HOW the causation works must be first-class; the 80% case stays flat gmeow:typeCauses (reify-on-demand, Principle 4). Whose claim it is rides the statement layer; two analysts' divergent links coexist (Principle 9).
Causal Modality
The force of a causal link — an OPEN value vocabulary seeded with necessitates (the antecedent suffices), promotes (raises likelihood), enables (makes possible), prevents (blocks). Distinct from gmeow:standpointModality (doxastic — how firmly a frame believes the link) and from gmeow:hasDeterminacy (ontic): causal modality is what the link CLAIMS about the world's mechanics.
Celestial Coordinates
A point on the celestial sphere expressed as right ascension, declination, and an optional epoch — frame-relative per Principle 11. The reference frame (ICRS, FK5, Galactic, etc.) is declared via gmeow:coordinateFrame.
Celestial Location
An astronomical location — a position on the celestial sphere, a solar-system body, a spacecraft, or a deep-sky object. The specific kind is given by gmeow:celestialObjectType (a value), not a subclass, so any astronomical object from star to galaxy cluster can be a first-class entity with its own coordinates and external identifiers (SIMBAD, NED, VizieR).
Celestial Object Type
The kind of an astronomical object (star, galaxy, nebula, planet, asteroid, spacecraft, etc.). A value, not a CelestialLocation subclass: the set is open-ended (IVOA object-type vocabulary lists ~100 types) and they share the same structure.
Celestial Reference Origin
The origin of a celestial coordinate system (topocentric, geocentric, barycentric, heliocentric, etc.). A value vocabulary aligned to IVOA refposition.
Certification
A reified attestation that a cryptographic key belongs to a given identity, made by a certifying agent (a PGP key-signature / Web-of-Trust certification). Its validity window is carried with gmeow:validFrom/validUntil; revocation sets validUntil.
Character Arc
A first-class interpretive/structural information object describing a character's trajectory through a narrative — a standpoint-scoped analysis, never canonical truth. A gufo:Kind with distinct identity criteria (subject, frame, and type). Cross-continuity variants are linked by counterpartOf, never merged.
Chunk
A contiguous segment of a source information object, produced by a chunking step for retrieval — the unit a retrieval returns, a model reads, and an evidence span pins into. Located in its source by gmeow:chunkOf + gmeow:spanStart/gmeow:spanEnd and content-addressed via the EXISTING gmeow:contentDigest (sources slice), so 'which exact bytes did the model see?' is answerable after the fact.
Citation Act
A reified citation: a citing entity cites a cited entity with a typed intent, optionally via a selector (a pinpoint into the cited work), carrying provenance, confidence, and standpoint. Replaces the old hasSource/citesSource: genealogical evidence is a CitationAct with intent intentCitesAsDataSource toward a creative work, via a selector. ENACTS rather than describes the cited work (kernel gmeow:hasAboutness gmeow:aboutnessEnacts): the act points at the work, it does not become a description of it.
Citation Intent
The intent with which one entity cites another — a VALUE vocabulary (individuals, never subclasses) characterizing a gmeow:CitationAct. Bridged by reference to CiTO sub-properties (e.g. cito:citesAsDataSource). The set is open.
Claim Veridicality
The veridicality status of a claim — whether it is untrue, licensed-false (fiction, satire, sarcasm), or true. A closed value vocabulary (individuals, never subclasses) that makes the licensed-falsehood safety property explicit, separating intentional deception from harmless fictional assertion.
Code Review
The event of reviewing code changes for quality, correctness, and policy compliance — an event (not an Activity, because reviewing is observation-like) with a reviewer, a merge request or commit under review, and an outcome. Distinct from gmeow:Review, which is the InformationObject artifact produced by the review. The event type is gmeow:eventTypeCodeReview.
Codec Class
The capability class of a transform codec — encode, compress, or encrypt (spec §8). Determines the degradation path when the capability is missing: unknown-codec or missing-key opacity.
Cognitive State
An agent's intrinsic knowing mode toward a subject — the mental moment grounding the knowledge spectrum and the reified gmeow:KnowledgeProficiency. The agent-side 'knowing' sibling of epistemics' doxastic states and teleology's gmeow:IntentionalMode, all gathered under gmeow:MentalMoment (kernel) so an agent's whole mental life is queryable as one family (Principle 15). Inheres in exactly one agent. NOTE: a CognitiveState (mode) and a gmeow:KnowledgeProficiency (relator) for the same knowing relation are DIFFERENT individuals — never double-typed (Principle 12).
Collection
An aggregation of resources published or curated as a unit — an anthology, album, gallery, or series bundle. A specialization of gmeow:Work whose members ride the universal gmeow:hasPart spine.
Collection Member Role
The role of a pitch within a collection — tonic/finalis, vādī, samvādī, ghammāz, ascent-only, descent-only, ornamental, or generic member. A value vocabulary of individuals; never subclassed (Principle 9).
Comment
A note that replies to an annotation or another comment — a threaded discussion node. Every Comment has exactly one commentParent (the annotation or comment being replied to). The transitive hasReply reaches all descendants in the thread. A note without a parent is a plain Note, not a Comment.
Commit
A version-control commit — a content-addressed provenance event that records a change to a repository's history. The history facet of the five-facet model; distinct from the project, product, codebase, and repository. Carries author and committer attribution, timestamps, parentage, and a content digest. Aligned to Software Heritage Revision and git commit objects by reference.
Commitment
A social commitment — an agent committed toward at least one other agent to bring about a goal (UFO-C: social moment). A relator, not a mode: it mediates the committed agent (gmeow:committedAgent) and the beneficiaries (gmeow:commitmentBeneficiary), who must be distinct (SHACL). A covenant, a contract promise, and a service-level agreement are Commitments; the agreements and contracts modules carry the document and the legal wrapper, this class carries the teleological bond itself.
Community
A graph-clustering community (Leiden or similar) over extracted-entity descriptions, at a level (gmeow:communityLevel) of the cluster hierarchy. The clustering run is provenance via the EXISTING gmeow:wasGeneratedBy.
Community Summary
A pre-generated summary of a community — GraphRAG's global-question substrate, gmeow:wasDerivedFrom the community's members and chunks and gmeow:wasGeneratedBy its generating invocation (EXISTING provenance), hence revisable rather than a black box.
Compliance Assessment
An observation that an event complied with or violated a norm — vantage = the assessor. The reified form of gmeow:violates / gmeow:complies, for when who-judged, on-what-evidence, and how-confidently must be first-class. Two assessors disagreeing are two coexisting cells; no global compliance verdict exists (Principle 9).
Concept
A category, schema, or abstraction held by an agent — a socially sustained cognitive representation. This is NOT the gUFO universal (which belongs to the gufo meta-level); a gmeow:Concept is a representational object sustained by agent usage and standpoint-indexed categorization claims.
Concept Categorization
A standpoint-indexed claim that an entity is categorized under a concept — the reified form of gmeow:instanceOfConcept. The vantage is the agent or standpoint making the categorization; the observedFeature is the categorized entity; the observationResult is the gmeow:Concept. Typicality, confidence, and accordingTo are reused from the standpoint and provenance layers.
Concept Tenure
The reified, time-scoped fact that a concept had a particular intension over an interval — conceptual change made first-class. When an agent community revises the definition or applicability of a concept, the old intension is retained as a closed tenure suppressed with gmeow:displayable false, never deleted (Principle 10). Carries its scope via gmeow:duringInterval (temporal module) and links to the concept via gmeow:conceptHoldsFor.
Condition
A describable circumstance — the trigger of a conditional norm, the activation context of a persona, the antecedent of a causal link (risk design). The canonical form is PROSE (gmeow:conditionText, mandatory by SHACL); machine formalizations attach via gmeow:formalizedAs, and each formalization is a claim of equivalence to the prose, challengeable through the statement layer. Whether the condition held at some moment is a gmeow:ConditionEvaluation — a vantage-indexed Observation — never a graph entailment. The ontology stores conditions; it never executes them (Principle 12).
Condition Evaluation
An observation that a condition held, did not hold, or could not be determined at some moment — vantage = the evaluator (an agent, a solver run, a model). The verdict is a recorded observation, NEVER a graph entailment: two evaluators returning different verdicts for one condition are two coexisting cells (Principle 9). The evaluation run itself attaches via gmeow:observationEvent; the evaluated condition rides gmeow:evaluatedCondition ⊑ gmeow:observedFeature.
Condition Expression
A machine formalization of a condition in a named expression language. STORED, NEVER EXECUTED: no CI step, test, or tool may evaluate a ConditionExpression against the graph as part of validation (Principle 12 made operational). Attaching one to a Condition (gmeow:formalizedAs) is a claim that the expression captures the prose — a claim like any other, carrying confidence and vantage through the statement layer.
Condition Group
A composite condition — all-of, any-of, or none-of its members (arbitrary and/or/not trees by nesting groups). Requires an operator and at least two members (SHACL). A group is itself a Condition: it carries its own prose summary and can be evaluated, formalized, and reused like any other.
Condition Parameter
A named binding that instantiates a condition template — 'threshold = 0.8', 'jurisdiction = Canada'. Lets one Condition serve many norms with different bindings.
Conflict Strategy
A policy conflict-resolution strategy — the ODRL conflict values perm / prohibit / invalid.
Connection
A reified traversable link between two entities, able to bear its own period, cost, weight, bandwidth, confidence, and standpoint. The flat shortcut is gmeow:connectsTo; promote to Connection when metadata matters.
Constraint
The abstract base of a condition on a rights rule (odrl:Constraint) — specialised by gmeow:AtomicConstraint (a leftOperand / operator / rightOperand comparison, e.g. dateTime ≤ 2030, spatial = EU, count ≤ 5) and gmeow:LogicalConstraint (a boolean combination of constraints). A licence's temporal bound is an AtomicConstraint over the dateTime operand.
Constraint Logic
The boolean operator of a logical constraint — odrl:and / odrl:or / odrl:xone (exactly one) / odrl:andSequence (ordered conjunction).
Constraint Operator
The comparison operator of an atomic constraint — the ODRL operator vocabulary (eq, neq, lt, lteq, gt, gteq, isPartOf, isA, isAnyOf, …).
Contact Point
A means of reaching an agent: an email address, telephone number, postal address, or instant-messaging handle.
Contact Point Type
The usage role of a contact point — a VALUE vocabulary (individuals, never subclasses). Personal, work, personal-domain, support, billing, and emergency are examples; the set is open. Projects to schema:contactType and the vCard TYPE parameter.
Containment Tenure
The reified, time-scoped fact that a place was contained in a larger place over an interval — for boundary changes, re-organisations, and disputed parallel parents. Reifies containedInPlace over time; the plain transitive property remains the flat shortcut.
Content Disposition
The presentation disposition of a body part — inline (displayed as part of the message body) or attachment (presented as a separate file). An open value vocabulary (individuals, never subclasses).
Content Origin
The reality-monitoring source of a piece of content — where it came from in the agent's mental economy: perceived from the world, retrieved from memory, held as belief, generated by imagining, entertained as a supposition, or synthesised by a generative process. A closed-but-open value vocabulary (individuals, never subclasses): gmeow:originPerceived, gmeow:originRemembered, gmeow:originBelieved, gmeow:originImagined, gmeow:originSupposed, gmeow:originGenerated. Implements the source-monitoring framework (Marcia Johnson, by reference): the discrimination an agent (or an auditor) makes between a recalled fact and a confabulated or machine-generated one. New origins are minted as individuals, never as subclasses (Principle 9: no overtyping).
Content Segment
A structural part of a creative work, release, or installment — a chapter, section, scene, or episode. A gufo:Kind with distinct identity criteria (position and type within a containing whole).
Content Segment Type
The structural type of a content segment — a VALUE vocabulary (individuals, never subclasses). Chapter, section, scene, and paragraph are examples; the set is open.
Content Transfer Encoding
The MIME content-transfer-encoding of a body part — the mechanism by which the part's content is encoded for transport. An open value vocabulary (individuals, never subclasses).
Contract
A legally enforceable agreement — an Agreement whose obligations are backed by a legal order, distinguished from a bare understanding only by that enforceability.
Contradiction
A reified conflict between two or more claim nodes — surfaced, attributed (gmeow:detectedBy), kind-classified (gmeow:contradictionKind), and NEVER resolved by rank. Conflicting claims coexist accordingTo their standpoints (P9); a standpoint may mark one refuted via the EXISTING gmeow:claimModality, but no winner machinery exists anywhere in the graph. Detection is itself contestable: two detectors disagreeing are two Contradiction individuals.
Contradiction Kind
An open value vocabulary of contradiction flavours.
Contribution
A reified relator binding a contributor (Agent), a contribution target (a Work, Expression, Manifestation, or Item), a contribution role, and an optional degree, carrying provenance, period, and confidence. THE universal credit construct; creative authorship, CRediT research roles, and mapping/software authorship are all Contributions. Flat shortcuts (gmeow:hasAuthor, gmeow:hasTranslator, …) cover the 80% query case.
Contribution Degree
The degree or weight of a contribution — a VALUE vocabulary (individuals, never subclasses) characterizing a gmeow:Contribution. Lead, equal, and supporting are the canonical seeds; the set is open.
Contribution Role
The role an agent played in contributing to a creative work — a VALUE vocabulary (individuals, never subclasses). Author, editor, translator, illustrator, narrator, composer, performer, director, photographer, and cover-artist are examples; the set is open.
Control Flow
A reified relator that connects two ProcedureSteps in a control-flow relationship — sequencing, branching, or looping. Reuses the Participation idiom: mediates a source step, a target step, and an optional guard condition (gmeow:flowGuard). The actual guard evaluation is solver-side (Principle 12).
Coordinate Matrix
A multi-dimensional numeric value expressed as a coordinate matrix or vector — the generalisation of ScalarQuantity to vector, matrix, and tensor results. Carries a serialised matrix literal (matrixValue), shape descriptor (matrixShape), reference frame (hasReferenceFrame), unit (hasUnit), and determinacy (hasDeterminacy). Used for colourspace tuples [j,k,l]+intensity, audio spectra, thermal images, and air-quality compound readings. The actual matrix algebra (dot products, transforms, decompositions) lives in the solver layer (Principle 12).
Coordinate Observation
A spatial measurement that assigns geographic coordinates or geometry to a place. Reifies the act of coordinate assignment so that multiple surveys (GPS 2023, LiDAR 2024) coexist as standpoint-indexed observations (Principle 9), each carrying its own reference frame, confidence, and temporal scope. Neither observation is 'the' coordinates. Superseded surveys are suppressed via gmeow:displayable false, never deleted (Principle 10).
Copyright
The reified copyright over a work — binding the work, its holder(s), the copyright year and the human-readable notice. Its status (in-copyright, public-domain, …) is a gmeow:copyrightStatus value aligned to RightsStatements.org / PREMIS.
Copyright Status
The copyright standing of a work — a VALUE aligned to the RightsStatements.org standardized statements and PREMIS copyright status. Open: a finer-grained statement is a fresh individual.
Corpus
An indexed collection of source information objects over which retrieval operates — the working document set behind a pipeline, distinct from the documents slice's bibliographic gmeow:Collection (a Work). Members via gmeow:corpusMember; content-addressable via the EXISTING gmeow:contentDigest, so an index can prove WHAT it indexed.
Correspondence
A single mapped element-pair within an gmeow:Analogy — the reified relation that one source element (gmeow:correspondingSource) plays the same structural role as one target element (gmeow:correspondingTarget). Reached from its analogy via gmeow:hasCorrespondence. The atom of structure-mapping: an analogy's systematicity is the structural consistency of its set of Correspondences.
Couple Relationship
A reified couple relationship (marriage, civil union, or partnership) between two persons; bears marriage, divorce and related events.
Coverage Depth
The depth of coverage a source provides about its subject — a value vocabulary (individuals, never subclasses). Distinguishes significant in-depth treatment from passing mention or routine filing. This axis is orthogonal to source tier and independence.
Creative Derivation
A reified relator binding a source creative work, a product creative work, one or more derivation types, and optional source/product segments. Tier-honest: a sample derives from a Recording region, a cover is a new Expression, and 'same Work?' is a separate standpoint-indexed gmeow:realizes claim (Principles 4, 9).
Creative Work
The abstract umbrella category for intellectual and artistic creations in the WEMI spine — a Work, Expression, Manifestation, or Item. Formerly a flat gufo:Kind (pre-WEMI spine); now a Category so that the four tiers with distinct identity criteria can each be a gufo:Kind beneath it.
Creative Work Title
An appellation borne by a creative work — a document title, article headline, dataset name, or media title. Carries its own gmeow:nameLanguage and gmeow:nameScript so co-equal multilingual titles (e.g. 'The Matrix' / '黑客帝国') are separate first-class objects, never alternateName subordinates.
Creative Work Type
The kind of a creative work — a VALUE vocabulary (individuals, never subclasses) characterizing a gmeow:Work. Literary, musical, visual, and software are examples; the set is open.
Credential
An educational or occupational credential held by an agent — a degree, certification, badge, license, or other attestation of qualification. Its issuer is gmeow:credentialIssuer, its subject matter is gmeow:credentialFor, and its verification is borne by a gmeow:Attestation (Principle 4).
Criterion
One evaluative axis of a rubric — what is being judged, with NAMED poles: a reward pole and a penalty pole that are small information objects with their own labels and definitions ('Power from the Bottom' vs 'Passive Victimhood'), not just numeric extremes. Anchors (gmeow:hasScoreAnchor) pin score ranges to meanings and exemplars.
Criterion Domain
The subject domain of a criterion — an OPEN value vocabulary (relational, factual, aesthetic, safety, stylistic, …). Open: evaluation traditions disagree about the domain inventory itself (Principle 9).
Criterion Pole
A NAMED extreme of a criterion — a small information object carrying its own label and definition. Poles are content, not numbers: 'Power from the Bottom' names what the high end rewards; 'Passive Victimhood' names what the low end penalizes. The numeric mapping lives on the scale and anchors.
Crypto Wallet
A digital wallet that holds cryptocurrency assets. A subclass of FinancialAccount (it is a financial-existence account) with wallet-specific properties: address(es), scheme, and cryptographic key linkage.
Cryptographic Key
A public key, certificate, or key material bound to an agent's identity — the thing a signature is made with and a certification vouches for.
Cryptographic Signature
A cryptographic signature over a message or its headers, asserting origin and integrity.
DKIM Signature
A DomainKeys Identified Mail signature (RFC 6376) over selected headers and the body.
Data Feed
A published, ordered stream of items — a syndication feed (RSS/Atom/JSON Feed), a timeline, an activity feed. A specialisation of gmeow:Collection; its items ride the universal gmeow:hasPart spine and project to schema:DataFeed / dataFeedElement / DataFeedItem.
Data Flow
A reified relator that connects a ProcedureStep's output to another ProcedureStep's input. Mediates a source step, a target step, and the data entity that flows between them.
Dataset
A collection of data published as a unit. A specialization of gmeow:Work.
Dating Method
The method used to derive a temporal measurement — radiocarbon, dendrochronology, thermoluminescence, etc. A value, never a subclass. Specialises gmeow:ObservationMethod for the temporal dating domain.
Day Of Week
A day of the week — a VALUE vocabulary (the seven ISO-8601 days as individuals); projects to schema:dayOfWeek.
Defeater Kind
The Pollock kind of a defeater — a value vocabulary (individuals, never subclasses): gmeow:defeaterRebutting (attacks the conclusion directly, giving reason to believe its negation) and gmeow:defeaterUndercutting (attacks the inferential link, removing the warrant without asserting the negation). Carried as a gmeow:defeaterKind value on a defeating gmeow:StandpointClaim.
Degree of Freedom
A reified relator that positively declares how a musical work or expression determines one musical parameter. Indeterminacy is not an absence; it is a declaration of status (fixed, constrained, free, or delegated). Each cell is {work/expression × parameter × determination status × optional constraint}; Cage's 4′33″ is fully specified by a set of such cells (Principles 9, 11, 12).
Deontic Modality
The deontic force of a norm — an OPEN value vocabulary (individuals, never subclasses) seeded with obligation (must), prohibition (must not), permission (may), and recommendation (should). Open so that supererogation, exemption, and other forces can join without schema change (Principle 9). Distinct from gmeow:standpointModality (doxastic — what a frame believes) and from gmeow:hasDeterminacy (ontic): deontic modality is what an issuer demands.
Depiction Context
The context in which an image depicts an entity — a VALUE vocabulary (individuals, never subclasses). Work, family, childhood, portrait, candid, formal, and so on; the set is open.
Depiction Usage
A reified, context-dependent depiction of an entity by an image — an observation in the universal claim stack (observation-spine bridge): an entity (depictionSubject) is shown in a given image (depictionImage), in a particular context (depictionContext), by or among a particular audience (depictionAudience), over a period (depictionInterval), asserted by an authority (depictionAuthority). Perspectival — a usage is whoever's, never a global fact — so it carries no notion of a preferred or canonical depiction. Mint one DepictionUsage per (entity, image, context) tuple; its period is carried by gmeow:depictionInterval or by validFrom/validUntil on the statement.
Derivation Kind
The kind of etymological derivation — a value, never an Entity subclass. Open-ended: new historical-linguistic frameworks may introduce further derivation types without ontology modification.
Derivation Type
The kind of creative derivation relating a source and product — a VALUE vocabulary (individuals, never subclasses). Cover, remix, sample, arrangement, transcription, quotation, and others are co-equal seeds.
Desire
An intentional mode of wanting without commitment — the agent would welcome the goal's satisfaction but has not committed to pursuing it (UFO-C: desire). Inheres in exactly one agent (gmeow:intentBearer). Promote a Desire to an Intention by minting the Intention and suppressing the Desire's tenure — never by mutation (Principle 10).
Determinacy
The model of ontic determinacy or indeterminacy for a value — whether it is inherently crisp, vague, fuzzy, probabilistic, or disputed. Distinct from epistemic confidence (how sure we are of a claim); determinacy records the nature of the value itself. Applies universally: a gender may be fuzzy, a date approximate, a boundary vague, a SLAM cell probabilistic, a contested fact disputed.
Determination Status
The status of a musical parameter within a DegreeOfFreedom relator — fixed, constrained, free, or delegated to performer/environment/process. An open value vocabulary of individuals; never subclassed (Principle 9).
Diff
A patch or diff — an information object describing the changes between two commits (or two trees). Carries textual diff content and references the from- and to- commits.
Disclosure Policy
The disclosure posture of a value or claim — an open value vocabulary of individuals (never subclasses) classifying whether and under what conditions the fact may be projected to consumers. The *what* layer of disclosure control: internalOnly, sensitive, publicCareful, publicSafe, neverPublic, or publicOnlyWithIndependentSource. Orthogonal to sensitivity, determinacy, confidence, and granularity (Principle 9). The conditional case (publicOnlyWithIndependentSource) is resolved against the evidence module's sourceIndependence axis in the solver layer (P12).
Distance Metric
An open value vocabulary of vector similarity/distance functions.
Distribution
A concrete distribution artifact of a software product — a tarball, wheel, binary, container image, or installer. The physical/bits facet of the release; identified by content digest.
Document
An abstract intellectual work of bounded textual or digital content — the conceptual document, independent of any particular file, record, or report. A specialization of gmeow:Work.
Documentation Concern
A cross-cutting documentation theme generated into its own guide page. Terms opt into a concern with gmeow:docsConcern so adoption-oriented docs are ontology-backed, not a private renderer taxonomy.
doxastic standpoint claim
A StandpointClaim that explicitly reports a held DoxasticState — the reified, vantage-indexed claim that an agent is in a particular believing mode toward a proposition. It carries the qualitative claimModality of the belief and links to the underlying DoxasticState via gmeow:claimOfBelief, so the holding can be justified or defeated in this module (Principles 9, 15).
Doxastic State
An agent's intrinsic believing mode toward a proposition — the reified, first-class mental moment that grounds the flat doxastic spine (gmeow:believes, gmeow:knowsThat). A sibling of cognition:CognitiveState (knowing) and teleology:IntentionalMode (desiring/intending) under kernel:MentalMoment, so an agent's whole endurant mental life is queryable as one family (Principle 15). Inheres in exactly one agent via epistemicAgent and is directed at exactly one Proposition via doxasticContent; its qualitative belief value is carried by a linked StandpointClaim (doxasticClaim → claimModality), and its graded strength by credence [0,1]. Never instantiated directly when the flat spine suffices (Principle 4).
Doxastic Tenure
The reified, time-scoped fact that a DoxasticState was held over an interval — the belief-revision history construct. Opened when the belief is adopted; closed (endedAtTime on the duringInterval) and suppressed with displayable false when the belief is revised or retracted. The old DoxasticState is retained as audit, never deleted (Principle 10). Carries its interval via gmeow:duringInterval (temporal module) and links to the scoped DoxasticState via tenureOfDoxasticState.
Dream Report
A recollection experience in which an agent reports or recalls a dream — a gmeow:Experience whose mental-process kind is gmeow:processRecollection and whose content originates in imagination (gmeow:contentOrigin gmeow:originImagined). A standpoint-indexed, low-metacognitive-reliability claim: competing reports coexist and superseded reports are suppressed, not deleted.
Duration
A length of time as a quantity, independent of when it occurs — the running time of an event, a gap, a recurrence period. Carries an xsd:duration via gmeow:durationValue. (= time:Duration / time:TemporalDuration, schema:Duration, ISO-TimeML TIMEX3 type=DURATION, TEO Duration.)
Duty
A rule that obliges the discharge of a gmeow:RightsAction (e.g. attribute, share-alike, obtain-consent) as a condition of a permission (odrl:Duty / odrl:obligation; CC REL cc:requires).
Dynamics Value
A symbolic dynamic level for a ToneEvent — ppp, pp, p, mp, mf, f, ff, fff. A value vocabulary of individuals; measured decibel values are frame-relative Observations outside this vocabulary (Principle 11).
Email Address
A contact point reachable via the Simple Mail Transfer Protocol (SMTP).
Email Message
An RFC 5322 email message, with headers, participants, a thread, body parts and mailbox residence.
Email Patch Diff
A patch or diff artifact between email body or header states, typically between a variant message and its canonical counterpart. Treated as a MIME-like BodyPart so it can carry mediaType, contentDigest, and derivation links.
Embedding
A vector representation of an information object (usually a core gmeow:Chunk), produced by an embedding model — the genuine vocabulary gap in the semantic-web stack (GraphRAG provenance design): model, dimensionality, and metric have no agreed RDF representation, so the refusal is recorded in the alignment trailer rather than papered over. The vector payload stays OUTSIDE the graph (gmeow:vectorRef, P12); the graph carries the provenance that makes it auditable.
Emotion
An emotion as an intrinsic mode inhering in one agent (the Desire/Intention grounding, teleology design). Episodic temporal scope rides validFrom/validUntil on the statement — deliberately no tenure class (thin means thin). Whether an emotion is self-reported or attributed is the vantage axis of the claims about it; self-report is top authority for the subject's own standpoint.
Emotion Type
The kind of an emotion — an OPEN value vocabulary seeded with Plutchik's primary eight (the EmotionML standard set). Registry-independent and contestable, never a tree (the Genre/Register precedent): traditions disagree about the emotion inventory itself, and that disagreement is data, not error (Principle 9).
Employment
A reified employment relationship between an agent and an organization, optionally founded on an employment contract and bearing a role, compensation, and employment type over a period. A specialization of gmeow:Membership: the employment-specific facets (compensation, seniority, employment type) are added here; the structural spine (member, organization, role, period) is inherited.
Employment Type
The kind of employment — a VALUE, never an Employment subclass. The set is open; a kind not among the seeds is a FRESH gmeow:EmploymentType individual carrying rdfs:label. Pointed at by gmeow:employmentType.
Entity
Anything in the GMEOW universe of discourse that persists in time and can bear properties: an agent, a document, a contact point, and so on.
Entity Existence
The reified, time-scoped fact that an entity existed over an interval — a gufo:Situation that carries its period via gmeow:duringInterval (inherited from TimeScopedRelation). Use when the existence claim is contested (two sources disagree on when a place ceased to exist), when evidence must be attached, or when standpoint indexing is needed. Flat-first: the common case uses gmeow:hasCreationEvent / gmeow:hasDestructionEvent / gmeow:existenceInterval directly on the entity.
Etymological Derivation
A provenance-rich claim about historical derivation between lexical items or forms. Not a flat property — a full relator carrying standpoint (accordingTo), confidence, determinacy, and temporal scope (Principle 9). Multiple derivations for the same target coexist without privilege; a superseded derivation is suppressed with displayable false, never erased (Principle 10). Follows the LanguageState / KinRelationship pattern as an Observation + Relator.
Evaluation Verdict
The outcome of a condition evaluation — held, not held, or undetermined. A closed three-member value vocabulary. Semantically the observationResult of a ConditionEvaluation, but not declared rdfs:subPropertyOf-reachable because QualityValues are disjoint from Entities in the DL profile (the claimModality precedent, standpoint module).
Event
A temporal occurrence in which entities participate in roles, over possibly fuzzy time, at possibly several locations, asserted by possibly conflicting sources. The universal event of the model: gmeow:Activity (provenance) and gmeow:LifeEvent re-parent onto it. The kind of occurrence is a gmeow:eventType value, never a subclass.
Event Invitation
A social act inviting an agent to attend an event, reified as a relator. Models the invitation as an Agreement to attend, reusing gmeow:hasParty for the invitee and the invitation status for the response state. Standpoint-indexed: a disputed invitation status is several coexisting claims, none privileged (Principle 9).
Event Schedule
A recurrence rule anchored to a template event and a time zone, generating a series of concrete Event occurrences. A relator mediating the template event, the recurrence rule, and the generated occurrences. Distinct from any one occurrence; the schedule is the generator, not the generated.
Event Series
A recurrence or schedule that issues a series of concrete gmeow:Event occurrences — a weekly standup, an annual conference. Distinct from any one occurrence; the recurrence rule is a projection concern (iCalendar RRULE), not a core property.
Event Type
The kind of an event — a VALUE, never a gmeow:Event subclass. The set is open; a kind not among the seed individuals is a FRESH gmeow:EventType individual carrying rdfs:label, not a new class. Pointed at by gmeow:eventType (non-functional).
Evidence Class
The kind and strength of evidence supporting a claim — a value vocabulary (individuals, never subclasses). Distinguishes verified facts from self-assertions, anecdotes, rumours, and refinements such as legal filings, trade press, or archive extracts. Coarse tiers and fine-grained refinements coexist; a claim may carry multiple evidence classes simultaneously (Principle 9).
Evidence Span
An anchored target span within a resource — a text quote, character position, fragment identifier, page, or generic locator. Generalized from the citation-selector model to serve both evidentiary claims (GraphRAG provenance design/EvidenceSpan audit machinery) and annotation targets (annotation target span). The selector properties (selectorTextQuote, selectorTextPosition, selectorPage, selectorLocator) are asserted on EvidenceSpan individuals and inherited by Selector instances. No second selector model is minted (Principle 4).
Exception Type
The kind of a schedule exception — a VALUE, never a subclass.
Execution
An event that enacts a Procedure or one of its ProcedureSteps. The execution side of the plan ⟂ execution de-conflation: an occurrence that realises a prescriptive spec. Reuses the existing event stack (Participation for agent/tool assignment, Allen relations for temporal ordering, eventInterval / eventTime for dating).
Execution Status
The status of an Execution occurrence — a VALUE, never a subclass. The set is open; new statuses are fresh individuals.
Exemplar
A citation act that holds something up as an example — positively, negatively, or as a cautionary boundary case. Pins into the cited work via the citation Selector machinery (page, quote, locator) AND/OR names an entity subject (gmeow:exemplarSubject — a character's conduct across a whole work, foundation-corpus coordination): at least one of the two (SHACL). The kernel aboutness axis carries the phase-gate: an exemplar whose span DESCRIBES trust is source material; one whose span ENACTS it is embodiment — same selector, different gmeow:hasAboutness, different anchored range. CiTO alignment arrives free through CitationAct.
Exemplar Polarity
The direction of an exemplar — a CLOSED three-member value vocabulary: positive (emulate this), negative (avoid this), cautionary (a boundary case that LOOKS positive but redirects or warns). Closed because the trichotomy is the design: finer judgement nuance belongs in the rationale and the anchored range, not in new polarities.
EXIF Tag
A reified EXIF metadata tag of a media object — a tag identifier (gmeow:exifTagId, e.g. 'FNumber'), its value (gmeow:exifTagValue, e.g. 'f/2.0'), and a human-readable label (rdfs:label, e.g. 'Aperture'). The schema:PropertyValue shape: reification keeps each tag's id/value/label paired correctly and lets an OPEN, camera-defined EXIF set round-trip losslessly to schema:exifData.
Experience
The phenomenally-conscious, qualia-bearing subset of gmeow:MentalProcess — a mental occurrence there is something it is like to undergo: a perception-as-experienced, a felt emotion-episode, a dream. Distinguished from sub-personal mental processing that carries no first-person character. The one genuine subclass in this slice; finer kinds remain gmeow:mentalProcessType values.
Expression
A realization of a gmeow:Work in a specific language, script, notation, or arrangement. The original-language text, a translation, and an audiobook narration are distinct Expressions of one Work. The realizing language/notation is carried as a reference frame (gmeow:hasReferenceFrame), not as a subclass. Identity changes when the language, notation, or arrangement differs.
Expression Language
The language of a condition expression — an OPEN value vocabulary seeded with the policy-engine and query languages GMEOW projects to: prose, SPARQL ASK, CEL, Rego, Cedar, XACML, SHACL. Open: new engines join without schema change.
Extracted Entity
A model-extracted entity DESCRIPTION — an information object about a putative entity, derived from source chunks. Deliberately NOT the entity itself: promotion to a first-class gmeow:Entity (with coreference by reference, never owl:sameAs — P5) is a separate, attributable curation act.
Extracted Relationship
A model-extracted relationship description between extracted-entity descriptions — the GraphRAG edge as a revisable, attributed artifact rather than a black-box triple.
Family
A kinship group of persons related by descent, marriage, or adoption.
Feed Posting
A short-form work published to a feed, timeline, or platform — a social-media post, a blog entry, a microblog note. A specialisation of gmeow:Work; its kind (social / blog / microblog) is an open gmeow:FeedPostingKind value, never a subclass. Carries the work metadata (title, author, datePublished) and may quote (gmeow:quotesContent) or share (gmeow:sharesContent) other content.
Feed Posting Kind
The kind of a syndicated posting — a VALUE vocabulary (individuals, never subclasses). Social, blog, microblog, forum, and status are examples; the set is open.
Filename
An appellation borne by a digital file — a stem and an extension. The extension CLAIMS a content type (gmeow:claimedMediaType) which may disagree with the type detected from the bytes (gmeow:detectedMediaType); the disagreement is recorded as coexisting claims with confidence, never reasoned into a contradiction.
Financial Account
A financial account held by an agent with a financial institution — a bank account, credit card, investment account, or wallet. Distinct from OnlineAccount (social profiles, decentralized identity): this is the financial-existence layer. The account's legal terms are modelled as an Agreement between the holder and the institution.
Financial Account Type
The kind of a financial account — a VALUE, never a FinancialAccount subclass. The set is open; a kind not among the seeds is a FRESH gmeow:FinancialAccountType individual carrying rdfs:label. Pointed at by gmeow:accountType.
Financial Transaction
A money-movement event — a payment, transfer, deposit, withdrawal, fee, interest, or refund. Reuses the Event/Participation substrate: payer, payee, and intermediary are ParticipantRole values on Participation relators, never subproperties. The kind of transaction is a TransactionType value; the status is a TransactionStatus value.
Forge Platform
A software forge or hosting platform — GitHub, GitLab, SourceHut, Codeberg, Gitea, etc. The platform as an entity, not any particular account or repository on it.
Form Function
An open value vocabulary of formal functions. Never subclassed (Principle 9).
Formal Language
A grammar-defined language with a machine modality and no human native speakers — programming, markup, query, logic, schema, and configuration languages. A thin structural split from gmeow:Language (the sociolinguistic facets — endonym/exonym, co-mingled scripts, native-speaker status — do not apply), complemented by the gmeow:languageOrigin value for fine-grained classification.
Foster Parent-Child
A parent-child relationship through fostering.
Frame Kind
The structural type of a reference frame (e.g. geodetic, Cartesian, polar, grid, narrative).
Frame Realm
The physical, virtual, or conceptual domain of a reference frame (e.g. terrestrial, indoor, celestial, virtual, measurement, currency, temporal, colourspace, linguistic).
GTS Compaction
An activity that rewrites a GTS document's frame layout — e.g. into delivery order for streaming (spec §3.2) or into a snapshot. Compaction re-authors only the ORDERING: content claims (ordinary quads, including signed statement-level claims) are rewrite-invariant by construction; transport claims over the source chain become detached evidence about the source document. The compacted document gmeow:wasGeneratedBy the compaction and gmeow:wasDerivedFrom the source document, whose segment heads remain citable through gmeow:gtsHeadId. Evidence-profile documents SHOULD NOT be compacted (see shapes); sealing the source verbatim as a nested GTS blob preserves its attestation intact.
GTS Document
A single-file Graph Transport Substrate artifact (docs/GTS-SPEC.md): a CBOR Sequence of one or more append-only segments carrying an RDF 1.2 graph and any content-addressed binaries it references. A Manifestation in the WEMI sense — the packaged, shippable embodiment. Its composite identity is the ORDERED list of its segments' chain heads (spec §3.1); byte-concatenation of valid documents is a valid document, so a document's segment list grows by append, never by rewrite.
GTS Profile
A named GTS profile (spec §13) — a purpose and requirement set a segment declares. An OPEN value vocabulary (individuals, never subclasses): extensions add their own profiles (e.g. a music package) without touching this module (Principle 9).
GTS Segment
One complete header-plus-frames log inside a GTS document — the unit of independent integrity (spec §3.1): a segment has its own genesis hash, its own id/prev chain, its own profile, its own transform catalog, and its own signers. Segments compose by concatenation and never vouch for one another; a third-party segment keeps its third-party attestation. Itself a Manifestation: a segment is a complete, independently shippable artifact.
Gender
A gender a person may identify with — a VALUE, never a gmeow:Person subclass. The set is open and culturally diverse; a gender not among the seed individuals is a FRESH gmeow:Gender individual carrying rdfs:label, not a new class. Pointed at by gmeow:genderValue.
Gender Expression
A person's SELF-ASSERTED gender expression — how they present (a gmeow:GenderExpressionStyle value via gmeow:expressionValue). A distinct axis from gender identity: expression is never inferred from identity (or vice versa), nor from sex or address.
Gender Expression Style
A style of gender expression — a VALUE pointed at by gmeow:expressionValue, never a subclass. Open: a style not seeded here is a fresh individual with rdfs:label.
Gender Identity
A person's SELF-ASSERTED gender identity — what they are — as a reified facet pointing (via gmeow:genderValue) to an open gmeow:Gender value. Independent of pronouns/honorifics (address), of gender expression, and of sex-assigned-at-birth; nothing infers any of these from another. Multiple co-equal GenderIdentity facets express bigender/genderfluid/transition without privileging any.
Generative Process
A process that is itself musical content — phasing, stochastic distribution, verbal score, algorithmic rule set. The rule text is human-readable data; formal evaluation is delegated to a solver referenced by processFunction (Principles 4, 12). Realizations are linked by gmeow:wasGeneratedBy.
Generative Process Kind
The kind of a generative process — phasing, stochastic, verbal score, rule-based, algorithmic. An open value vocabulary of individuals; never subclassed (Principle 9).
Genre
A contested, registry-independent, lineage-bearing information object used to characterise creative works. Like gmeow:Language, a genre is a first-class individual-bearing class; it is never a subclass tree and never a privileged winner of a genre dispute (Principles 5, 9).
Geo Coordinates
A geographic point expressed as latitude, longitude, and optional elevation.
Geocode
A geographic location code expressed in an alternative geocoding reference frame — a Plus Code, what3words address, geohash, MGRS grid reference, UN/LOCODE, or linear-referencing mile-marker.
Geometry
The spatial extent of a place — a point, line, or polygon — carrying a Well-Known Text (WKT) serialization for shapes richer than a single point (the GeoSPARQL geo:Geometry superset).
Geometry Type
The structural kind of a geometry (point, line, polygon, multipoint, multilinestring, multipolygon). A value vocabulary (individuals, never subclasses) aligned by reference to GeoSPARQL simple-features (sf:Point, sf:LineString, sf:Polygon, etc.).
Goal
A described state of affairs that an agent may want, intend, or commit to bring about — the propositional content of the intentional modes, existing by social convention like every description (a gmeow:SocialObject). A goal asserts nothing and prescribes nothing by itself: it is satisfied by situations (gmeow:satisfiedBy), held by agents (gmeow:hasGoal or the reified modes), and partly defined by its named shadow (gmeow:counterGoal). Whether a given situation satisfies the goal is a vantage-indexed claim (Principle 9).
Governance Model
The governance model of a project — a VALUE vocabulary (individuals, never subclasses). Describes how decisions are made and who has authority.
Grammatical Aspect
The grammatical aspect of an event mention in text — a VALUE vocabulary for ISO-TimeML interoperability (perfective / progressive / perfective-progressive / none).
Grammatical Tense
The grammatical tense of an event mention in text — a VALUE vocabulary for ISO-TimeML interoperability (past / present / future / none). Describes the linguistic realization, not the occurrence.
Granularity Level
A level of detail / resolution at which a value is expressed — a point on an open, ordered, domain-general axis (spatial: point ≺ address ≺ city ≺ region ≺ country; temporal: day ≺ month ≺ year ≺ decade ≺ century). The explicit facet behind 'no silent precision', and the axis that gmeow:coarsenTo generalizes along. Levels are individuals (never per-level subclasses), ordered by gmeow:coarserThan and aligned to external resolution vocabularies (OWL-Time time:TemporalUnit, ISO 19112 LocationType) by skos:exactMatch.
Graph Box Role
A documentation and validation role describing which graph layer a term, shape, module, or graph artifact primarily serves: assertional data (ABox), terminology/schema (TBox), role/property behavior (RBox), contextual statement metadata (CBox), or runtime/package/profile configuration (ConfigBox). Roles are descriptive annotations, may be multi-valued, and never partition the ontology into exactly one box per resource.
Groove Profile
A systematic, repeatable deviation from a strict metric grid — swing ratio, per-grid-position offsets, or a measured microtiming profile. Groove is content, not error (stress case 17).
Groove Profile Kind
The kind of a GrooveProfile — swing ratio, per-grid-position offsets, or a measured profile. A value vocabulary of individuals; never subclassed.
Group
A collection of agents treated as a unit without the formal structure of an organization.
Group Operator
The combination operator of a condition group — a closed three-member value vocabulary: all (conjunction), any (disjunction), none (negated disjunction).
Harmonic Function
An open value vocabulary of harmonic functions. Never subclassed (Principle 9).
Hazard
A bearer's disposition toward harm — manifested, when it manifests at all, as events of a feared type (gmeow:manifestedAsType). A hazard that never manifests is still fully real as a disposition: the first gufo:Disposition use in GMEOW, and the reason this slice needs no counterfactual machinery. The bearer may be anything that can carry a disposition: a system, an agent, a relationship, an artifact.
Highlight
An annotation that marks an anchored span within a target and carries no body — a pure target+selector binding motivated by highlighting.
Holding
A reified relator connecting an agent to a financial asset with a quantity and cost-basis. The thing that is held: agent × asset × quantity × cost-basis × optional period. Promote from a flat accountBalance when cost-basis, period, or provenance must be recorded.
Honorific
A title or form of address (Mr, Mx, Dr, -san, Sri, Sayyid, …). A value, not a subclass. Each carries a gmeow:honorificPosition (prefix/suffix) and, where applicable, a gmeow:honorificClass.
Honorific Class
The domain of an honorific (academic, clerical, noble, military, judicial, social).
Honorific Position
Whether an honorific is rendered before (prefix) or after (suffix) the name.
Identifier
A reified external-identifier record bundling a scheme-local value with its scheme, and optionally the authority URL that resolves it and a human-readable name — an ORCID, a geni profile id, a Nostr nip05, a LEI, a ROR ID, a NAICS code. Reification ensures that when an entity carries multiple identifiers, each value is paired with its correct scheme (and url/name) in projections. The structured sibling of gmeow:authorityLink: a flat authorityLink points at an external record by IRI; an Identifier decomposes the scheme/value/url/name a schema:PropertyValue or DataCite relatedIdentifier carries.
Identity Facet
A reified, SELF-ASSERTED claim about an aspect of a person's identity — an observation in the universal claim stack (observation-spine bridge): gender identity, gender expression, or (in the sexuality module) sexual/romantic orientation — mediating the person (facetSubject / observedFeature) and an open identity value. A gufo:Relator and a gmeow:Observation, the same idiom as gmeow:NameUsage. A person bears MANY co-equal facets (e.g. bigender); none is privileged, there is no preferred/primary marker, and a superseded facet is kept with gmeow:displayable false rather than deleted. Self-assertion (gmeow:selfAsserted) is the top authority; the optional validity period is carried by gmeow:validFrom/validUntil on the facet.
Image Region
A region within an image — a structural part of a gmeow:MediaObject, described by a gmeow:RegionSelector that encodes its boundaries. The counterpart of ContentSegment for visual media: a face, an object bounding box, a polygon, or a pixel mask. Carries a human-readable gmeow:regionLabel.
Import Activity
An activity that ingested an external source artifact (an import envelope such as a vCard file) and recorded the claims it carried. Carries the ingestion (transaction) time — when the system learned the claims, distinct from when they were asserted or when they hold.
Index Algorithm
An open value vocabulary of vector-index structures.
Inference Commitment
The endurant, structured argument relation an inference instantiates — the reified Toulmin/Peircean commitment mediating its premises (gmeow:premise), its single conclusion (gmeow:conclusion, a gmeow:StandpointClaim), its warrant (gmeow:warrant), its mode (gmeow:inferenceModeOf), and its defeaters (gmeow:hasDefeater). A relator, not a process (the gmeow:Commitment idiom): the occurrent reasoning episode that bears it is the gmeow:InferenceProcess reached by gmeow:hasInferenceCommitment. Reifying is the on-demand tier; the flat 80% case hangs gmeow:inferredFrom + gmeow:inferenceMode directly on the conclusion-claim. Retained as audit when its conclusion is suppressed (belief revision), never erased (Principle 10).
Inference Mode
The Peircean mode of an inference — a closed-but-open value vocabulary (individuals, never subclasses; the gmeow:StandpointModality idiom): gmeow:modeDeduction, gmeow:modeInduction, gmeow:modeAbduction, gmeow:modeAnalogical. The mode rides as a gmeow:inferenceMode value on the claim (or gmeow:inferenceModeOf on the commitment), never as a subclass of gmeow:InferenceCommitment (Principle 9: no overtyping). The modes differ by warrant and default modality, not by subsumption.
Inference Process
The occurrent reasoning episode — inference as it unfolds in time, drawing a conclusion from premises. The perdurant face of inference: a gmeow:MentalProcess borne by exactly one gmeow:experiencer and carrying gmeow:mentalProcessType gmeow:processReasoning, the reparenting hook the mentation slice reserves. It gmeow:producesMentalMoment the belief it creates and reaches its argument structure via gmeow:hasInferenceCommitment. Distinct from the endurant gmeow:InferenceCommitment (the argument relation it instantiates) — keeping the gUFO endurant/occurrent split clean.
Inference Tenure
The reified, time-scoped fact that an gmeow:InferenceCommitment's conclusion was held over an interval — opened when the conclusion is accepted and closed when a defeater fires, never deleted (Principle 10). Belief revision is the closing of a tenure (and gmeow:displayable false on the conclusion-claim), not the erasure of the commitment, which survives as audit. Carries its interval via gmeow:duringInterval (temporal module). Use only when the adoption / retraction of the conclusion is itself worth modelling; the common case is a bare claim with its modality.
Information Object
An entity whose nature is to carry information content: a document, dataset, software artifact, online account, or message. The shared parent of the document, software and account layers.
Inline Part
A body part displayed inline within the message body, such as an embedded image or a text/html part rendered as part of the message content. Distinct from Attachment in presentation intent but not declared disjoint — a part's disposition is an attributed fact, not a rigid kind boundary (Principle 9).
Inquiry Tenure
The reified, time-scoped fact that an agent held an open question over an interval — an inquiry opened in January and closed by an accepted answer in June is an opened-then-closed tenure, never a deletion (Principle 10). The StandpointTenure idiom applied to inquiry: use only when the opening / closing of an inquiry is itself worth modelling; the common case is a bare gmeow:asks with validFrom / validUntil on the statement. Carries its interval via gmeow:duringInterval (temporal module); a closed tenure is kept with gmeow:displayable false.
Inscription
The sign-bearing content or mark on a physical carrier — a text, sequence of signs, or symbolic marking that is informationally distinct from the material object that bears it. An inscription is an InformationObject; its carrier is a PhysicalObject. Multiple inscriptions may coexist on one carrier, and competing readings of the same inscription coexist without privilege (Principle 9).
Inscription Reading
A scholarly reading of an inscription — the Observation that produces a LexicalForm from a sign-bearing feature. The reading is a standpoint-scoped claim, not ground truth: two scholars may read the same marks differently, and both readings coexist (Principle 9). Follows the universal Observation + Relator pattern.
Inscription Translation
A translation of an inscription into another language — an Observation that produces a LexicalForm representing the meaning of the source inscription in a target language. Standpoint-scoped: competing translations coexist without privilege (Principle 9).
Inscription Transliteration
A transliteration of an inscription into another script — an Observation that maps sign sequences from one writing system to another, producing a LexicalForm. Standpoint-scoped: competing transliteration schemes (e.g. Hepburn vs Kunrei-shiki) coexist without a single winner (Principle 9).
Instant
A zero-duration point in time, distinct from a TimeInterval. Carries a crisp instantValue (xsd:dateTime) and/or an edtfValue (EDTF literal) relative to a TemporalFrame.
Instant Message Address
A contact point reachable through an instant-messaging or chat service — a handle, channel, or service-scheme URI (xmpp:, weixin:, matrix:, …).
Instrument Configuration
A configured instrument setup — a relator binding an instrument item or type, one or more modifications, a tuning frame, and an interval. The prepared-piano / drop-tuning answer (instruments and configurations). A physical instrument and a software instrument are both first-class subjects; no new instrument-item class is minted (Principles 4, 9, 11).
Instrument Modification
A modification applied to an instrument in an InstrumentConfiguration — prepared, scordatura, capo, mute, electrified, extended range, etc. An open value vocabulary of individuals; never subclassed (Principle 9).
Instrument Type
The kind of a musical instrument — piano, violin, drum kit, voice, etc. An open value vocabulary of individuals; never subclassed (Principle 9). Each individual may carry a Hornbostel–Sachs code (gmeow:hsNumber) and a MIMO exactMatch (Principle 5).
Intention
An intentional mode of internal commitment — the agent has settled on pursuing the goal (UFO-C: intention), though no other agent holds them to it. Inheres in exactly one agent (gmeow:intentBearer); aims at exactly one goal (gmeow:intentionGoal); may motivate events (gmeow:motivates). The social grade — committed TOWARD someone — is gmeow:Commitment.
Intention Tenure
The reified, time-scoped fact that an agent held an intentional mode over an interval — a goal adopted in January and abandoned in June is an opened-then-closed tenure, never a deletion (Principle 10). The StandpointTenure idiom applied to teleology: use only when adoption / revision is itself worth modelling; the common case is a bare gmeow:hasGoal with validFrom / validUntil on the statement. Carries its interval via gmeow:duringInterval (temporal module); a withdrawn tenure is kept with gmeow:displayable false.
Intentional Mode
The abstract category of intrinsic intentional moments — desires and intentions — that inhere in exactly one agent and aim at a goal. The intrinsic branch of gmeow:IntentionalMoment, and the conative member of the kernel gmeow:MentalMoment family (alongside cognition's gmeow:CognitiveState and epistemics' doxastic states) so an agent's whole mental life is queryable as one family (Principle 15) — gmeow:MentalMoment ⊑ gufo:IntrinsicMode supplies the gUFO branch. Never instantiated directly: instances are Desires or Intentions (the commitment-graded trichotomy; the social grade is gmeow:Commitment, a relator, not a mode).
Intentional Moment
The umbrella category of all goal-directed moments — UFO-C's intentional moment, spanning the intrinsic branch (gmeow:IntentionalMode: desires and intentions inhering in one agent) and the social branch (gmeow:Commitment: a relator toward other agents). Exists as a NAMED class so that gmeow:intentionGoal and gmeow:motivates carry a generator-visible domain instead of an anonymous union (the schema surface — LinkML, GraphQL, TypeScript — projects properties from named domains only). Never instantiated directly.
Interpersonal Relationship
A reified standing relationship between agents (acquaintance, collaboration, …), able to bear its own time interval, confidence, and source evidence.
Invitation Status
The status of an event invitation — a VALUE vocabulary aligned to iTIP PARTSTAT, never a subclass.
Invoice
A billing document issued by a seller to a buyer, requesting payment for goods or services rendered. A subclass of Document.
Invoice Status
The status of an invoice — a VALUE, never a subclass. Open vocabulary.
Issue
A tracked issue, ticket, or bug report in a software project — an InformationObject that may carry title, body, labels, and state. The event of its creation/closure is a separate gmeow:Event.
Item
A single exemplar of a gmeow:Manifestation — one copy. An InformationObject; a physical copy is linked via gmeow:hasCarrier to a gmeow:PhysicalObject, keeping informational identity distinct from the physical carrier. Library circulation/holdings detail is out of scope for this base (carrier hook only). Identity changes when you hold a different physical or digital copy.
Journal Entry
A balanced double-entry bookkeeping event: a temporal occurrence in which debits equal credits (per currency bucket). Composed of two or more Posting relators.
Jurisdiction Tenure
The reified, time-scoped fact that a place was governed by a particular polity over an interval — a sovereignty or administrative jurisdiction claim. Non-functional on the place: contested sovereignty (e.g. Crimea-class) is modelled as multiple co-existing JurisdictionTenures, each standpoint-indexed and confidence-weighted, never collapsing to a single winner (Principle 9).
Justification Ground
The class of things that can serve as a justification basis — an evidence span, an attestation, or a further doxastic state. Introduced as a named superclass so that schema projections can assign a single range to gmeow:justifiedBy instead of losing a blank-node owl:unionOf.
Justification Status
A value vocabulary for justification-defeat states of a doxastic state or standpoint-claim — solver-set flags such as Gettier-case, defeated, undercut, and rebutted. These are quality values (gufo:QualityValue) attached via gmeow:defeatedBy; the reasoner never infers them (Principle 12).
Justification Subject
The class of things that can carry justification or defeat relations — a doxastic state or a standpoint claim. Introduced as a named superclass so that schema projections (LinkML, TypeScript, GraphQL) can assign a single domain to gmeow:justifiedBy and gmeow:defeatedBy instead of losing a blank-node owl:unionOf.
Key Scheme
The cryptographic scheme/format of a key (OpenPGP, X.509, SSH, Nostr, …). Modelled as a value, not a key subclass: the set of schemes is open-ended and they carry no distinct key structure here, so a new scheme is a new individual, not a new class.
Kin Relationship
A reified kinship relationship between persons, modelled as an observation (a claim-from-a-vantage) in the universal stack (observation-spine bridge). Able to bear its own events, dates, sources, and standpoint-indexed claims. A disputed kinship is several coexisting gmeow:accordingTo-annotated relators, none privileged (Principle 9). The relationshipParent and relationshipChild are co-observed features of the observation.
Knowledge Level
The graded epistemic depth of a knowledge-proficiency — an OPEN, ordered value vocabulary (knowledgeAware ≺ knowledgeKnowsAbout ≺ knowledgeUnderstands ≺ knowledgeMastered), the kernel GranularityLevel pattern. Ordinally parallels the flat knowledge spectrum (gmeow:isAwareOf … gmeow:hasMastered) but as reusable values on the reified relator. gmeow:deeperThan is transitive ON LEVELS ONLY; the boundaries are deliberately vague (only the order is asserted).
Knowledge Proficiency
A reified, leveled depth-of-knowledge of an agent toward a subject — the gufo:Relator binding {agent} × {subject} × {level on a scale} × {interval}, mirroring expertise's gmeow:SkillProficiency. Founded on the gmeow:CognitiveState mode (documentation, not an axiom — Principle 12); the mode and this relator are DIFFERENT individuals, never double-typed. Flat-first: the four-level knowledge spectrum (gmeow:isAwareOf … gmeow:hasMastered) is the cheap surface; promote to a KnowledgeProficiency when level, scale, temporal scope, or standpoint matters. Suppression not deletion (Principle 10): lapsed knowledge is recorded as a closed interval / gmeow:displayable false, never deleted. Boundaries, documented WITHOUT axiom bridges (Principle 9): cognition (knowing, objectual) ⊥ epistemics (believing, propositional); cognition ⊥ expertise (knowing ⊥ can-do — gmeow:hasSkill ⊑ gmeow:knowsAbout touches the axes at one rung only).
Land Tenure
The reified, time-scoped fact that a party holds rights over a place — ownership, lease, easement, mortgage, usufruct, or another property right. Bridges the locations module to the rights module by referencing RightsStatement. Distinct from JurisdictionTenure (governance/sovereignty) and RegulatoryOverlay (regulation): LandTenure is about property rights. Contested titles coexist as multiple standpoint-indexed instances, never collapsing to a single winner (Principle 9).
Land Tenure Type
The kind of a land tenure (ownership, leasehold, easement, mortgage, usufruct, freehold, crown lease, etc.). A value, not a subclass: the set is open-ended and they share all of LandTenure's structure, so a new kind is a new individual, not a new class (Principle 9).
Language
A language as a first-class information object with a self-minted IRI: a system of signs/symbols and rules used for communication or computation. Registry-INDEPENDENT — BCP-47/ISO 639/Glottolog/Wikidata are optional alignments (gmeow:languageCode, gmeow:authorityLink, skos:exactMatch), never identity, so a code-less conlang or AI-generated language is fully first-class. Origin, modality and status are open value vocabularies; the scripts it is written in are bound co-equally via gmeow:WritingSystemUsage; its endonym/exonym names are gmeow:Appellation.
Language Change Event
A historical linguistic change — sound shifts, semantic drift, borrowing, spelling reform, grammatical change, lexical innovation, standardization, language contact, extinction, revival, or revitalization. Follows the LanguageCreation pattern as an Activity subclass; change type is an open value vocabulary (gmeow:LanguageChangeType) and affected languages are linked via gmeow:affectedLanguage. Temporal placement and participation reuse the universal events machinery.
Language Change Type
The kind of historical linguistic change — a value, never an Entity subclass. Open-ended: new analytical frameworks may introduce further change types without ontology modification.
Language Creation
The activity of creating or generating a language — a conlanger's design work or an AI model's generation run. Linked to its product by gmeow:wasGeneratedBy (the language → activity) and to its agent by gmeow:wasAssociatedWith; the language is ascribed to its creator with gmeow:wasAttributedTo (a gmeow:SoftwareAgent for an AI-generated language).
Language Modality
The sensory/transmission channel of a language (spoken, signed, written, whistled, tactile, machine, multimodal). A value carried by gmeow:languageModality.
Language Origin
How a language came to be (natural, constructed, AI-generated, formal, pidgin, creole, reconstructed, …). A value, not a Language subclass: origins are open-ended and share Language's structure.
Language Proficiency
A reified, leveled proficiency of an agent in a language, in a particular skill modality — the gufo:Relator binding {agent} × {language} × {skill modality} × {level on a scale}, mirroring names' gmeow:NameUsage. Mint one per (agent, language, modality) so 'native overall' and 'B2 writing' coexist. The base gmeow:knowsLanguage relation states that an agent knows a language; this relator adds the level and the skill.
Language State
A reified, standpoint-scoped claim about the status of a language, variety, or version during a specific interval — the analytic/historical slice of a language at a time/period, often reconstructed and standpointed. Follows the VersionMembership pattern: a relator binding {language} × {status} × {authority} × {interval}. Differs from LanguageVersion, which is a named/released artifact; a version can have states, and a state can describe a version, but neither is defined as the other.
Language Status
The vitality status of a language (living, historical, extinct, dormant, revived, emerging, proposed, constructed-active). A value carried by gmeow:languageStatus.
Language Variety
A speech variety that carries names, scripts, tags, status, provenance, and alignment metadata exactly as a gmeow:Language does, because it IS a language (a SubKind). Classifications such as dialect, sociolect, register, or standard are standpointed claims via gmeow:varietyKind, not OWL subclass decisions — so a single variety can be classified as a language by one standpoint and a dialect by another without incoherence (Principle 9).
Language Variety Kind
The sociolinguistic classification of a language variety — a value, never an Entity subclass. Standpoint-scoped: 'dialect' according to one authority may be 'language' according to another. The seed list is an anchor, not a fence.
Language Version
A concrete, dated revision of a language that is itself a fully usable language (Ithkuil 1993 / 2011 / New Ithkuil; an AI language v1 / v2). Subclass of gmeow:Language so a version bears its own scripts, names and status; gmeow:versionOf links it to the lineage language, gmeow:supersedes orders versions, and gmeow:wasDerivedFrom records derivation. Forward-looking for rapidly-versioned AI languages.
Learning Event
The occurrent that transitions an agent along the cognition knowledge spectrum or the expertise proficiency scale — learning as it unfolds in time: an acquisition, a being-taught, a consolidation, a transfer, an unlearning. The perdurant complement of the endurant knowledge STATES (cognition's gmeow:KnowledgeProficiency, expertise's gmeow:SkillProficiency): those say what an agent knows, a gmeow:LearningEvent is the event that CHANGED what it knows. A gmeow:MentalProcess (the reparenting hook the mentation slice reserves), so it is borne by exactly one gmeow:experiencer and joins the agent's single occurrent mental-timeline stream; its variety is a gmeow:learningType value, never a subclass (Principle 9).
Learning Event Type
The variety of a learning event — a value vocabulary spanning concept-formation, skill-acquisition, being-taught, consolidation, transfer, and unlearning: gmeow:learningConceptFormation, gmeow:learningSkillAcquisition, gmeow:learningBeingTaught, gmeow:learningConsolidation, gmeow:learningTransfer, gmeow:learningUnlearning. Its members are individuals, never subclasses (Principle 9), more than one may co-apply to a single event, and the set is OPEN — a variety not among the seeds is a fresh gmeow:LearningEventType individual. The dedicated learning analogue of the inference slice's gmeow:InferenceMode.
Ledger Account
A book-keeping account in a double-entry ledger — an asset, liability, equity, revenue, or expense account. An InformationObject distinct from FinancialAccount: a LedgerAccount is a conceptual book-keeping construct, while a FinancialAccount is a bank-level account with IBAN/BIC/number.
Ledger Account Type
The kind of a ledger account — a VALUE, never a LedgerAccount subclass. The set is open; a kind not among the seeds is a FRESH LedgerAccountType individual carrying rdfs:label. Pointed at by gmeow:ledgerAccountType.
Ledger Event
An event emitted by a smart contract or recorded on a ledger — a log entry, oracle callback, or bridge message.
Ledger Finality Status
The finality state of a ledger transaction or block — a value vocabulary (individuals, never subclasses).
Ledger Transaction
A transaction recorded on a distributed ledger or blockchain — the information-object representation of the payload, not the on-chain bytes themselves.
Left Operand
The dimension an atomic constraint tests — an OPEN value vocabulary mirroring the ODRL leftOperand vocabulary (dateTime, spatial, count, purpose, recipient, industry, …).
Lexical Form
A concrete form of a lexical item — written, spoken, signed, rendered, reconstructed, normalized, transliterated, or translated. The surface representation is carried by gmeow:formRepresentation; the kind of form is a gmeow:LexicalFormType value. A single lexical item may have many coexisting forms (Principle 9). Aligns to OntoLex Form by reference.
Lexical Form Type
The kind of a lexical form — a value, never an Entity subclass. The seed list is an anchor, not a fence; new analytical frameworks may introduce further form types without ontology modification.
Lexical Item
The abstract lexical or constructional object: a word, morpheme, phrase, idiom, symbol, sign, or construction. Carries no surface form itself; forms are linked via gmeow:hasLexicalForm. Aligns to OntoLex LexicalEntry by reference, but is broader than names (which are modeled in the names module as Appellation).
License
A licence granting rights in a work — modelled as a gmeow:Agreement (it binds licensor and licensee and creates permissions / duties). The canonical superset of cc:License / an ODRL Offer / dcterms:LicenseDocument. Its validity window rides gmeow:validFrom / gmeow:validUntil; its family is a gmeow:licenseFamily value.
License Family
The family of a licence — public-domain, Creative Commons, permissive, copyleft, proprietary, or dual. An OPEN value vocabulary; the ontology-side reflection of the config.py license classification, not a duplicate of it.
Life Event
An event in the life of a person or family — a birth, death, marriage, christening, name change, and so on — to which sources and confidence can be attached. A thin, person-scoped phase of gmeow:Event (NOT a type taxonomy): the specific kind is a gmeow:eventType value (gmeow:eventTypeBirth, …). The seam joining the names module to the event spine: gmeow:conferredByEvent ranges over it.
Literary Work
An abstract long-form story or textual work — fiction, poetry, drama, or literary non-fiction. A specialization of gmeow:Work.
Location
A locus where an entity can be situated, reside, or occur — a geographic place, an online (virtual) location, a digital storage location, or an astronomical/celestial position.
Location State
The state of a moving entity at a specific point or period in time, including its location, velocity, and pose (position + orientation).
Logical Constraint
A boolean combination of constraints under a gmeow:constraintLogic operator (odrl:and / odrl:or / odrl:xone / odrl:andSequence) over its gmeow:logicConstraintMember constraints — the ODRL LogicalConstraint, modelling the deontic constraint logic.
Mailbox
A named container of messages within an account — a folder, JMAP mailbox, or Gmail label.
Mailbox Residence
The reified, time-scoped fact that a message resided in a mailbox/label over an interval (membership is time-varying — messages move between folders and labels).
Mailing List
An email distribution list — an InformationObject identified by a List-Id and serving as the hub for list metadata, subscription, and archiving.
Maintenance Status
The maintenance status of a software project — a VALUE vocabulary (individuals, never subclasses). Answers the question 'is this maintained?' Standpoint-scoped: one community may judge a project abandoned while another considers it stable (Principle 9).
Manifestation
A concrete edition, format, or release that embodies a gmeow:Expression — a rights-bearing publication artifact (the 2003 Penguin paperback, the 2011 Kindle EPUB). gmeow:BookRelease, gmeow:SerialInstallment, gmeow:MediaObject, and gmeow:WebPage are specializations. Identity changes when the publication/format/edition differs.
Manifestation Format
The physical or digital format of a Manifestation — a VALUE vocabulary (individuals, never subclasses). Hardcover, paperback, EPUB, PDF, audiobook, vinyl, and web-page are examples; the set is open.
Mark
A brand / sign / name / logo that can be trademarked — the thing a gmeow:Trademark protects (schema:Brand). An information object: it may itself bear a gmeow:RightsStatement (logos are also copyright works).
Maxim Violation Type
A value vocabulary for conversational maxim violations (Gricean maxims: quality, quantity, relation, manner).
Measured Value
An alias for gmeow:Quantity — the measured-value perspective on the same value×unit/frame×determinacy×provenance bundle (ScalarQuantity alias precedent). Equivalent to gmeow:Quantity and gmeow:ScalarQuantity. Provided for consumers who prefer the 'measured value' terminology common in metrology and sensor standards.
Measurement
An observation that assigns a quantitative or qualitative value to a feature of interest, typically carrying a unit, uncertainty, and determinacy model. The parent of temporal dating, spatial coordinate assignment, and scalar quantity measurements.
Media Object
An image, audio, or video media file — a concrete published artifact. A specialization of gmeow:Manifestation.
Membership
The reified relationship by which an agent is a member of an organization, optionally playing a role over a period of time. A gufo:Relator binding {member} × {organization} × {role} × {post} × {period}, foundedOn the agreement that constitutes it — the same relator idiom as names' NameUsage and contacts' InterpersonalRelationship. The reify-on-demand promotion of the flat gmeow:memberOf shortcut (Principle 4).
Memory Item
An observation/claim in the role of an agent's remembered belief (gmeow:memoryOf the remembering agent; gmeow:memoryKind the cognitive register). A gufo:Role on the UNIVERSAL claim construct — any claim form can be remembered, and being remembered is contingent, never an essence. Belief revision is supersession with gmeow:displayable false (P10), never deletion: what an agent believed WHEN is a query, not an archaeology project. The substrate under the gmeow client's Memory and the MCP store/recall/revise triad (P14).
Memory Kind
An open value vocabulary of agent-memory registers.
Mental Moment
The umbrella category of all agent mental states — intrinsic modes inhering in exactly one agent that constitute its cognitive / doxastic / conative life: knowing (cognition's gmeow:CognitiveState), believing (epistemics' doxastic states), and desiring/intending (teleology's gmeow:IntentionalMode). A NAMED class so a consumer can query ALL of an agent's mental moments uniformly (the agent-memory flagship, Principle 15) and the schema surface projects a single mental-state parent. Never instantiated directly.
Mental Process
A mental occurrence that unfolds in time — the perdurant (occurrent) counterpart of the endurant gmeow:MentalMoment: a perceiving, a reasoning, an imagining, a remembering, a dreaming. The kernel-level umbrella under which every mental event lives, so an agent's mental life can be queried as a single occurrent stream. A gmeow:Event borne by exactly one agent (gmeow:experiencer); the kind of process is a gmeow:mentalProcessType value, never a subclass (Principle 9). gmeow:InferenceProcess (inference slice) and gmeow:LearningEvent (learning slice) reparent under it from their own slices.
Mental Process Type
The kind of a mental process — a closed-but-open value vocabulary (individuals, never subclasses; the gmeow:EventType idiom): gmeow:processPerception, gmeow:processAttention, gmeow:processReasoning, gmeow:processImagining, gmeow:processDeliberation, gmeow:processRecollection, gmeow:processMindWandering, gmeow:processDreaming, gmeow:processLearning. New kinds are minted as individuals, never as subclasses of gmeow:MentalProcess (Principle 9: no overtyping).
Mental Reference Frame
A subjective or internal reference frame in which standpoint-indexed values are expressed — e.g. a thermal comfort scale, an olfactory quality space, a subjective loudness frame, an affective valence/arousal space (Russell circumplex), a conceptual geometry (Gärdenfors), a cognitive map (egocentric or allocentric), or an imagined space (memory palace, dream). A MentalReferenceFrame is a ReferenceFrame whose realm is perceptual or psychological and whose axes describe qualitative or semi-quantitative dimensions of human, animal, or AI experience. Requires a host (the perceiver, thinker, or dreamer); the frame deactivates when its host ceases to exist. Distinct from measurement frames: two hosts may map the same external stimulus to different mental-frame coordinates (Principle 11).
Merge
The event of merging one branch of development into another — an activity with a merge-base commit, a source branch or ref, a target branch, and a resulting merge commit. The event type is gmeow:eventTypeMerge.
Merge Request
A proposed merge of one branch into another — an InformationObject carrying title, description, source branch, target branch, and review state. Aligned to GitHub Pull Request and GitLab Merge Request by reference.
Message
A communication sent from one agent to others — the parent of email and other message kinds.
Message Header
A single RFC 5322 header field (name and value) of a message.
Message Keyword
A flag/keyword applied to a message (IMAP flag or JMAP keyword) such as seen, flagged, answered, draft, forwarded, or junk.
Message Kind
The behavioral or report kind of a message — a VALUE vocabulary (individuals, never subclasses). Categories can overlap (a bounce is also auto-generated; a read receipt is also auto-generated). Principle 9: no single category wins.
Message Participant
A reified occurrence of an email address in a particular message header or envelope context.
Message Participant Role
The role an address occurrence plays in a message header or envelope.
Metacognitive State
An agent's intrinsic SECOND-ORDER mental moment — a state whose subject is one of the agent's OWN first-order mental moments or claims (a belief about a belief, a confidence about a confidence, an awareness of a gap in one's knowledge). The reflexive sibling of gmeow:CognitiveState (the knowing mode) and gmeow:IntentionalMode (the conative mode), gathered under gmeow:MentalMoment (kernel) so an agent's whole mental life is queryable as one family (Principle 15). Inheres in exactly one agent. Its reflexivity edge is gmeow:metaTarget; its calibration rides gmeow:calibration.
Meter Assignment
A reified relator binding a carrier (e.g. a voice), a MetricStructure, and a MusicalTimeSpan. Consecutive assignments model bar-by-bar changes; concurrent assignments on different carriers over one shared TempoMap model polymeter (stress case 14).
Metric Group
One ordered group within a MetricStructure, carrying a rational length and an optional accent weight. Additive meters are sequences of MetricGroups.
Metric Kind
The computational method by which distance or dissimilarity is measured in a reference frame — geodesic (curved surface), Euclidean (straight-line in Cartesian space), cosine (angular similarity in latent vector space), edit-distance (Levenshtein / sequence alignment), or graph-hops (shortest-path in a network). A value vocabulary (individuals, never subclasses) per Principle 9.
Metric Modulation
A reified relator declaring a transition from one MusicalTimeFrame to another via a pivot equivalence expressed as a rational pair (e.g. 3/8 = 1/4). The pivot resolution is solver-evaluated (Principle 12).
Metric Structure
A recurring grouping cycle that defines a meter — an ordered set of MetricGroups with rational lengths and optional accent weights. Covers additive meters (2+2+3 aksak), fractional meters (2/10), tala, colotomic cycles, and the absence of meter when no structure is asserted.
Mitigation
A reified countermeasure binding: a measure — a gmeow:Norm or a Procedure (procedures extension) — set against a causal link or hazard it counters. The measure range is intentionally OPEN (the tenurePosition precedent, fourth use): the P16 DAG rule bars extension→extension dependencies, and the open range lets the deontic and procedural worlds plug in without axiom coupling. The D3FEND countermeasure and bowtie barrier map here at alignment time. Whether a mitigation WORKED is a vantage-indexed claim, never an entailment.
Mitigation Status
The lifecycle status of a mitigation — an OPEN value vocabulary seeded with proposed, active, retired. Retirement is suppression-shaped: a retired mitigation is kept with its status, never deleted (Principle 10).
Model Card
A structured description of a model agent (gmeow:describesModel): provider, version tag, context window, training cutoff. Aligns Model Cards / ML-Schema / SPDX-AI by reference (P5). The card is a document ABOUT the agent; capability claims are claim-layer observations, attributed and contestable.
Model Invocation
One call to a generative model: the model agent (gmeow:usedModel), the prompts presented (gmeow:hasPrompt), and the sampling parameters. The provenance anchor of every generated claim — a claim node gmeow:wasGeneratedBy its invocation and gmeow:wasAttributedTo the model agent (both EXISTING provenance properties), so 'which model, under which prompt and parameters, at what time?' is answerable after the fact. Outputs are linked FROM the output via gmeow:wasGeneratedBy; no forward output property exists (P5).
Monetary Amount
A quantity of money expressed as a decimal value in an explicit currency reference frame. The canonical superset of schema:MonetaryAmount and FIBO fibo-fnd-acc-cur:MonetaryAmount. Frame-relative (Principle 11): a value without its currency frame is ill-formed.
Motif
An identity-bearing recurring narrative unit — a theme, leitmotif, symbol, running gag, tale type, or trope ('Melisande's Game', 'the Cassiline vow'). NOT a folksonomy string: a motif carries aliases (names module Appellations), a kind, frame-scoped claims, and occurrences riding the narration seam (gmeow:motifOccursIn ⊑ gmeow:narratedIn, narration seam — inheriting the flat-by-default efficiency discipline). Motif-hood is itself interpretive: one vantage's tag is another's motif, and both readings coexist (Principle 9). Cross-work identity goes through gmeow:counterpartOf or a shared registry anchor (Thompson Motif Index, ATU — alignment window), NEVER string equality. The tags module remains the right home for uncurated labels; the promotion heuristic (tag → motif when recurrence and identity emerge, recorded as an Activity with provenance) lives in docs.
Motif Kind
What sort of recurring unit a motif is — an OPEN value vocabulary: theme, leitmotif, symbol, running gag, tale type, trope. Never a tree (Principle 9).
Multipart Body Part
A MIME container part that holds other body parts — the structural node of a multipart/alternative, multipart/mixed, multipart/related, or other multipart subtype. It is itself a BodyPart and participates in the MIME tree via the universal hasPart / partOf spine.
Multipart Type
The MIME multipart subtype of a MultipartBodyPart — an open value vocabulary (individuals, never subclasses). Standard subtypes are seeded; new subtypes (e.g. form-data) are added as individuals.
Music Analysis Claim
A reified musical-analytical observation: {analysisTarget × analysisProperty × analysisResult × analyst-vantage × theory-frame}. Inherits confidence, displayable, and determinacy from Observation (Principles 9, 11, 14).
Musical Parameter
A dimension of musical content whose degree of determination a work or expression declares. An open value vocabulary of individuals; never subclassed (Principle 9).
Musical Segment
A structural part of a musical work or expression — a graph node carrying musical content at any granularity. Modelled as a gufo:SubKind inheriting identity from gmeow:ContentSegment; ONE class for every granularity, with specific levels (riff, motif, phrase, section, talea, color, ...) as values of segmentKind, never subclasses (Principle 9).
Musical Time Frame
A reference frame for musical time — a one-dimensional rational-position axis relative to which durations, spans, tempi, and mappings are expressed. Per-voice frames are supported via gmeow:isHostedBy (Principle 11).
Musical Time Span
A frame-relative span of musical time, delimited by a rational start position and a rational duration in an explicit MusicalTimeFrame. The musical-time analogue of gmeow:TimeInterval; clock-time conversion is performed by fnMusicalToClockTime (Principle 12).
Musical Work
A work whose primary content is music — the abstract artistic conception independent of any particular notation, performance, or recording. A specialization of gmeow:Work; identity is unaffected by realization mode or notation system (Principles 4, 9, 11).
Myth
A socially-sustained narrative whose currency is independent of its truth-value — a founding myth, an urban legend, a propaganda narrative, or a debunked claim that persists. GMEOW asserts no truth verdict on a myth (Principle 1); in-myth claims are scoped accordingTo an associated gmeow:NarrativeReferenceFrame. A myth is the abstract narrative (WEMI Work level); concrete tellings are linked via gmeow:hasMythTelling.
Name Part
A reified component of a structured appellation — a given name, a surname, a patronymic, a nobiliary particle, an Arabic nisba, a filename extension. Its kind is the value gmeow:namePartType, its text is gmeow:partText, and gmeow:partOrder records its position WITHOUT implying a Western given-before-family order.
Name Part Type
The kind of a name part (given, surname, patronymic, particle, Arabic nisba, filename extension, …). A value, not a NamePart subclass: naming systems worldwide contribute an open-ended set of part kinds that share NamePart's structure.
Name Purpose
The purpose/kind of a whole appellation (legal, birth, chosen, professional, deadname, …). A value, not a PersonName subclass; a person may simultaneously bear several co-equal names of different purposes.
Name Register
The social register of a name-usage (formal, intimate, professional, casual) — the naming specialization of the gmeow:Register umbrella: a name register IS a register, so persona expression and name address draw from one vocabulary spine. A value vocabulary carried by gmeow:usageRegister on a gmeow:NameUsage.
Name Usage
A reified, context-dependent use of an appellation — an observation in the universal claim stack (observation-spine bridge): a named entity (observedFeature) is called by a given appellation (observationResult), by or among a particular audience (or within a relationship scope), in a particular register, over a period, on some evidence. Perspectival — a usage is whoever's, never a global fact — so it carries no notion of a preferred or canonical name. Mint one NameUsage per (appellation, audience, register) tuple; its period is carried by gmeow:usageInterval or by validFrom/validUntil on the statement.
Named Period
A named stretch of time with defined bounds — a geologic era, historical dynasty, artistic period, fiscal year, or any other culturally salient temporal division.
Narration Mode
HOW a segment carries its content — an OPEN value vocabulary (individuals, never subclasses) seeded with the diegetic-level ladder: narrated (direct), mentioned (referenced without narration), flashback (narrated out of story order), dream (framed as a character's dream), hypothetical (framed as possibility), unreliable (narrator credibility in question — the deception-module boundary,: documented bridge, no axiom coupling).
Narration Usage
The reified seam link — segment × narrated subject × mode, for when HOW the text carries the content matters: flashback, dream, hypothetical, unreliable narration. Mint one per (segment, subject) pair needing mode/vantage/confidence; the 80% case stays flat gmeow:narrates (efficiency doctrine — reify-on-demand, Principle 4). Whose reading of the mode it is rides the statement layer; competing modes for one narration usage are coexisting relators, none privileged (Principle 9).
Narrative Frame Link
A reified relator that binds a source narrative frame, a target narrative frame, and the relation type between them into a single node. The canonical form when the specific frame-to-frame relation must itself be a node (e.g. to attach provenance, confidence, temporal scope, or standpoint); the flat shortcuts are gmeow:hasNarrativeFrameRelation and gmeow:relatesToFrame. Structurally the Tagging/NameUsage idiom wearing a different hat.
Narrative Frame Relation
The relationship of one narrative frame to another — a value vocabulary (individuals, never subclasses) spanning canon, alternate continuity, expanded universe, fanon, crossover, and adaptation. Non-functional: a frame may hold several relations to another frame from different standpoints.
Narrative Position
A frame-relative position in a narrative — the narrative analogue of SpatialCoordinates. Carries its frame (mandatory: a position without a frame is the bare-integer anti-pattern this class exists to forbid), an ordinal (chapter_index 31), a label ('Thirty-Three', 'the Longest Night'), or both. Ranges are expressed as paired positions. Comparison, ordering, and discourse↔story reconciliation are solver-layer computations (Principle 12).
Narrative Reference Frame
A canon, continuity, or narrative realm that serves as a reference frame for in-universe facts (locations, dates, events) and functionally as the standpoint under which in-universe claims hold true. The Harry Potter canon, the Marvel Multiverse (Earth-616, MCU, Ultimate), and the Star Wars Legends/Canon split are all narrative reference frames. Ordinary GMEOW entities (Person, Place, Organization, Event) may carry claims according to this frame; cross-continuity variants are linked by counterpartOf, never merged.
Narrative Role
A character's narratological function — an OPEN value vocabulary (protagonist, antagonist, mentor, foil, narrator, confidant, love interest, trickster, …), Propp/Greimas-informed but never closed: traditions disagree about the role inventory itself (Principle 9). A role is a FUNCTION RELATIVE TO A SCOPE, not an intrinsic property — carried by the RoleInNarrative relator, never by typing the character.
Narrative Scope
The umbrella category of things a narrative role can be relative to — a creative work (protagonist of the trilogy), a narrative reference frame (protagonist of the continuity), or a content segment (protagonist of one chapter). A NAMED class (the IntentionalMoment/RiskFactor precedent) so roleScope carries a generator-visible range and the relator-arity gate sees the end. Never instantiated directly.
Narrative Time Axis
The axis kind of a narrative time frame — a value vocabulary (individuals, never subclasses) of exactly two members: discourse time (syuzhet, the order of telling) and story time (fabula, the order of happening). Both are first-class and neither wins (Principle 9): the discourse order is not an approximation of the story order, and the story order is not the truth of the discourse order.
Narrative Time Frame
A coordinate system for narrative position — the reference frame in which 'where in the story' is expressed. Exactly one axis kind per frame: discourse time (the order of telling — chapter indices, scene ordinals — owned by the telling work, since different editions may re-segment) or story time (the order of happening in-universe — the fabula — owned by a NarrativeReferenceFrame, since continuities can reorder it). The same diegetic event may carry coexisting positions in a discourse frame and a story frame; their disagreement IS the flashback, made queryable rather than contradictory.
Neo-Riemannian Operation
An open value vocabulary of Neo-Riemannian operations. Never subclassed (Principle 9).
Network Address
A network-layer address or locator expressed as a coordinate in a network reference frame — an IP address, MAC address, DNS name, URL, port number, or BGP autonomous-system number. The flat shortcut for the common case is gmeow:accessUrl on a VirtualLocation; promote to NetworkAddress when frame, provenance, confidence, or standpoint matters.
Network Address Type
The kind of a network address (IPv4, IPv6, MAC, DNS, URL, port, BGP-AS). A value, not a subclass: the set is open-ended and they share all of NetworkAddress's structure, so a new kind is a new individual, not a new class (Principle 9).
Norm
A prescription existing by social convention — an obligation, prohibition, permission, or recommendation issued by an agent or standpoint over some conduct. A norm asserts nothing about the world: it records that an issuer prescribes. Whether anything complies is a vantage-indexed ComplianceAssessment; what wins when norms conflict is solver work over the recorded precedence claims (Principle 12). Every modality-bearing norm must name its issuer (SHACL): there is no ought, only ought-according-to (Principles 1, 9). GROUNDING: a gufo:Category at Entity level — the IntentionalMoment precedent — because the rights graft places gmeow:Rule (⊑ gufo:Relator) beneath it while plain standalone norms are object-like social descriptions; committing Norm to gufo:Object OR gufo:Relator would make one branch inconsistent (Object ⟂ Aspect), and a Kind would stack identities under the rights trio (OntoUML MixIden). The social-convention reading lives on the concrete classes: NormativeSystem ⊑ SocialObject, the trio ⊑ Relator.
Normative System
A body of norms with a shared identity — a constitution, a legal code, a code of conduct, a principia document, a rubric set. Member norms attach via gmeow:partOf. A normative system is itself issued (gmeow:systemIssuer), and competing systems coexist without inconsistency: GMEOW records what each prescribes and never adjudicates between them (Principles 1, 9).
Notation Projection Profile
A closed descriptor schema for the lossy projection from frame-relative content to one notation system. Declares representable parameters, incurred losses, and the FnO projection function that performs the render (Principles 4, 11, 12).
Notation System
A structured symbolic system with defined rules for representing information in a specific domain — mathematical notation, musical notation, stenography, phonetic transcription, or cryptographic encoding. Distinguished from a language by lacking independent generative syntax/semantics; parasitic on or encoding for an existing language or domain (Principle 9).
Notation System Usage
A reified, role- and period-scoped use of a notation system by an entity — an observation in the universal claim stack (observation-spine bridge): the gufo:Relator binding {entity} × {notation system} × {role} × {period}, mirroring names' NameUsage and languages' WritingSystemUsage. Lets a language use IPA for phonetic transcription, a musical work use Western staff notation, or a text use Morse code for encoding, each co-equally and standpoint-scoped.
Notation Usage Role
The role a notation system plays in a specific usage — a value, never an Entity subclass. Open-ended: new analytical frameworks may introduce further roles without ontology modification.
Note
A piece of content in a personal or collective knowledge graph — an annotation body, a Zettelkasten card, a comment, or a standalone thought. Grounded as an information object whose authorship is mediated by Participation / wasAttributedTo, whose temporal scope is carried by the four clocks, and whose standpoint is indexed by accordingTo. Reuses isAbout and hasTag / Tagging for topic and tagging; does not mint parallel properties.
Observable Property
A physical, chemical, biological, or environmental property that can be observed or measured by a sensor. A value vocabulary (individuals, never subclasses) so any new property — from temperature to neural activation to social sentiment — is a new individual, not a new class (Principle 9).
Observation
A reified act of observing, measuring, or asserting a feature of interest — the universal claim construct unifying spatial measurement, temporal dating, sensory reading, standpoint claims, identity claims, naming claims, rights claims, and kinship claims. Mediates between an observer (vantage), a feature (observedFeature), and a result (observationResult). Every observation carries at least a vantage and an observedFeature (EL open-world); closed-world cardinality is SHACL's concern.
Observation Method
The method or protocol by which an observation was made — a value vocabulary (individuals, never subclasses). Generalizes gmeow:DatingMethod (temporal module) and subsumes sensor types, survey protocols, laboratory techniques, archaeological procedures, and standpoint assertion methods. A method is constitutive of the observation: changing the method changes the observation's identity (it is a different act).
Observation Type
The kind of observation being made — a value vocabulary (individuals, never subclasses). Distinguishes measurement, sensory reading, standpoint claim, derived inference, and simulation output. The specific sub-discipline (radiocarbon dating, GPS survey, temperature sensing) is gmeow:observationMethod, not gmeow:observationType.
Observational Activity
An activity whose primary purpose is to produce observations — a scientific survey, census, archaeological excavation, clinical trial, code review, audit, or any other structured act of observing, measuring, or asserting. A subclass of gmeow:Activity (and therefore of gmeow:Event) that generates gmeow:Observation individuals as first-class outputs. The event-type value vocabulary (gmeow:eventTypeSurvey, …) marks specific kinds; no subclass taxonomy is introduced (Principle 9).
Occupancy
A measurement of the current number of entities located at or within a location. The location is the observedFeature; the result is a ScalarQuantity. Typically computed by the solver layer from locatedAt relationships and active LocationState instances (P12), but may also be asserted directly from sensor readings or manual counts.
Occupation
A kind of work or profession, such as those classified by ESCO, SOC, or O*NET. Classifications are carried as open code values (gmeow:occupationClassification), never as OWL subclasses (Principle 9).
Offering
A commercial offer to provide some item — a product, a service, an engagement — by an agent. Projects to schema:Offer. The item is named by gmeow:itemOffered; the provider by gmeow:offeringProvider.
Online Account
An account an agent holds with an online service — a social profile, code-forge account, or decentralized identity.
Online Service
An online service or platform an account is held with — a social network, code forge, email provider, or federated instance. Carries the service's liveness (gmeow:serviceStatus / gmeow:serviceShutdownDate) so historical services (Yahoo 360, Google+) remain first-class with their shutdown recorded.
Opacity Reason
Why a frame is opaque to a given reader (spec §7.6) — a missing capability or damage. An open value vocabulary; opacity is vantage-relative, so the reason is a fact about a reader-frame pair, not about the bytes.
Opaque Frame
A sealed or undecodable region of a GTS segment, surfaced by the reader as a first-class object rather than dropped (spec §7.6): an encrypted frame the reader holds no key for, a frame using a codec the reader lacks, or a damaged frame. Opacity is VANTAGE-RELATIVE epistemic state, not a property of the bytes — the same frame is transparent to a recipient holding the key (standpoint/privacy, Principle 9). The frame's bytes remain present, hash-linked, and chain-verifiable.
Opening Hours Specification
A reified opening-hours window — a day (or set of days), an opening time and a closing time. Projects to schema:OpeningHoursSpecification. Reification keeps each window's day/open/close paired correctly when several coexist.
Order
A purchase order or sales order — an agreement between a buyer and a seller for the supply of goods or services at a stated price. A subclass of Agreement.
Order Status
The status of an order — a VALUE, never a subclass. Open vocabulary.
Organization
A structured group of agents — a company, institution, association, or governmental body — able to act as a single agent.
Organization Name
An appellation borne by an organization — a legal name, a trading / 'doing-business-as' name, or a former name.
Organization Type
The kind of an organization — a VALUE, never an Organization subclass. The set is open; a kind not among the seed individuals is a FRESH gmeow:OrganizationType individual carrying rdfs:label, not a new class.
Orientation
The rotational component of a pose, expressed as co-equal optional facets: quaternion (x, y, z, w), Euler angles (yaw, pitch, roll plus order), or compass angles (heading, bearing). No single representation is privileged; multiple representations may coexist for the same pose. Aligns by reference to IEEE 1872-2015 pos:OrientationMeasure.
Ornament Profile
A named convention for ornamentation — a gamaka family, a baroque agrément, a jazz turn — bound to segments or voices. Completes the raga/maqam model by separating structural pitch membership from expressive execution (Principles 9, 11).
Ornament Profile Kind
The kind of ornament profile — gamaka family, baroque agrément, raga ornament, jazz turn, etc. An open value vocabulary of individuals; never subclassed (Principle 9).
PGP Signature
An OpenPGP signature (RFC 4880/9580, PGP-MIME RFC 3156) over a message, bound to a PGP key.
Package
A distributable software package — a named, versioned unit of software published through a package ecosystem (npm, PyPI, Cargo, Maven, etc.). The package descriptor, not the concrete distribution artifact.
Parent-Child Relationship
A reified parent-child relationship, typed by its nature (biological, adoptive, step, or foster).
Participant Role
The role an entity plays in an event — a VALUE, never a participation subproperty. The set is open; a role not among the seeds is a FRESH gmeow:ParticipantRole individual with rdfs:label. Carried by gmeow:participationRole on a gmeow:Participation.
Participation
A reified participation of an entity in an event, in a role, over a period, on some evidence — the same relator idiom as gmeow:NameUsage. Mint one Participation per (event, participant, role) tuple when role / period / confidence / evidence must be recorded; the 80% case uses the flat gmeow:hasParticipant. Perspectival and co-equal: a disputed role is several standpoint-indexed Participations that coexist, none privileged; a withdrawn one is kept with gmeow:displayable false, never deleted.
Patent
An abstract intellectual work describing an invention — the inventive concept as claimed, independent of any granted or filed document. A specialization of gmeow:Work.
Payment
A payment event — a financial transaction whose purpose is to discharge an obligation or transfer value. A thin subclass of FinancialTransaction distinguished by the paymentMethod facet.
Payment Method
The method or instrument used to make a payment — a VALUE, never a subclass. Open vocabulary.
Performance Decision
A reified relator recording one documented traversal of a mobile form during a performance — the performance event, the traversal constraint, and the chosen sequence of fragments. Competing traversals of the same work coexist as distinct PerformanceDecisions (Principle 9).
Performance Participation
A reified participation in a musical event — a performance, recording session, take, overdub, rehearsal, or transmission. Adds music-specific details (instrument type, specific instrument item, configuration, part, technique) to the universal gmeow:Participation relator. Playing bass on take 3 is event involvement expressed here, not a third relator (Principles 4, 9).
Period Type
The kind of a named period (geologic eon, era, period, epoch, age; historical dynasty, era; fiscal year). A value, never a subclass.
Permission
A rule that grants the ability to exercise a gmeow:RightsAction over the governed asset (odrl:Permission). Its required duties ride gmeow:hasDuty.
Person
An individual human being, living or deceased.
Person Name
A structured, typed name borne by a person — birth name, married name, chosen name, alias, religious name — with ordered, typed name parts, an optional honorific, a script/language, and a purpose (gmeow:namePurpose). A person bears many co-equal PersonNames (across life stages and across languages/scripts); their validity period is carried with gmeow:validFrom/validUntil on the bearing statement or by a gmeow:NameUsage.
Persona
A reified expression policy of one agent — the relator binding {bearer} × {register(s)} × {expressed norms} × {activation context}. PRIMARY and PRIVATE are two Personas of one agent; 'Dr. Chen at the clinic' and 'Mom at home' are two of another. No primaryPersona exists or ever will (Principle 9): personas are co-equal, context-activated, and withdrawn by suppression, never deletion (Principle 10). Register-switching is not deception — divergence of held and projected standpoints is the deception module's territory, a documented boundary with no axiom coupling.
Physical Carrier Type
The archaeological or cultural-heritage classification of a physical object that bears inscriptions, marks, or signs — a value vocabulary (individuals, never subclasses). Open-ended: new carrier kinds are minted as needed without ontology modification.
Physical Object
An entity that is a material thing occupying space and time — a device, instrument, vehicle, building, or natural body. Distinct from Agent (which acts and bears responsibility) and InformationObject (which carries information content). The sortal for pose-bearing, sensor-hosting, and spatially-located things that are not agents.
Pitch Anchor
A binding between one degree of a TuningSystem and a physical frequency in an explicit acoustic frame (e.g., A440 vs Baroque A415). Hz is never asserted directly on a PitchValue; it is reached only through fnPitchToFrequency(value, anchor) (Principles 11, 12).
Pitch Collection
A set or multiset of PitchValues derived from a source (a spectrum, a tuning system, an analysis, or a projection). A projection of canonical frame-relative content, not the canonical object itself (Principle 4).
Pitch Collection Kind
The kind of a pitch collection, drawn from an open value vocabulary of individuals (scale, mode, maqam, jins, raga, thaat, pathet, mode of limited transposition, pitch-class set, row/series, spectrum collection). Never subclassed (Principle 9).
Pitch Collection Membership
A reified relator binding a pitch collection, a member pitch value, the role that pitch plays, and an optional context/standpoint. The canonical way to assert that a pitch belongs to a collection with a specific function; contested memberships are co-equal relators carrying distinct gmeow:accordingTo annotations (Principles 2, 9).
Pitch Expression
A common superclass for pitch-related quantities that are expressed relative to a TuningSystem. PitchValue and PitchInterval are its subkinds; using a named class avoids anonymous union classes as property domains in generated schemas (Principle 4).
Pitch Interval
A frame-relative directed interval between two pitch values, expressed as an exact ratio or in cents. Intervals are not subclasses of PitchValue; they are a distinct kind of frame-relative quantity (Principle 9).
Pitch Spelling
A reified relator binding a frame-relative pitch value, a pitch spelling system, and a spelled name string. Note names (C♯4, sargam Ga, Johnston +7) are projections, not canonical pitch values; enharmonic ambiguity is modelled as two co-equal spellings of the same pitch (Principles 4, 9, 11).
Pitch Spelling System
A named system for spelling frame-relative pitches as note names or symbols — e.g. Common Music Notation staff letters, sargam solfege, Johnston accidentals. A local vocabulary in the music slice; aligned to external notation standards by reference in mappings (Principles 4, 5, 16).
Pitch Trajectory
Continuous pitch as content — an ordered set of control points (musical-time × PitchValue) plus an interpolation kind. Models glissandi, gamaka ornaments, UPIC curves, and other continuously varying pitch (stress case 6). Interpolation is solver-evaluated, never reasoner-asserted (Principle 12).
Pitch Trajectory Control Point
One ordered (musical-time, PitchValue) pair belonging to a PitchTrajectory.
Pitch Trajectory Interpolation Kind
The interpolation mode of a PitchTrajectory — linear in cents, exponential, or stochastic-by-reference. A value vocabulary of individuals; never subclassed (Principle 9).
Pitch Value
A frame-relative musical pitch — an exact rational ratio or a cents offset expressed relative to an explicit TuningSystem. Pitch letters (C4, F#) are projections, not canonical values (Principle 11).
Place
A geographic location at any granularity — a country, region, city, thoroughfare, site, building, floor, or room. The specific kind is given by gmeow:placeType (a value), not a subclass, so any level can be a first-class place with its own coordinates and external identifiers.
Place Name
An appellation (toponym) borne by a geographic place via gmeow:hasPlaceName — possibly endonym/exonym (gmeow:namePurpose), multilingual, or historical (held over a period via a gmeow:NameUsage / inferred gmeow:PlaceNaming). The structured, first-class replacement for the retired flat gmeow:alternateName literal, used for gazetteer matching and co-equal multilingual/historical naming.
Place Naming
A DEFINED specialization of gmeow:NameUsage whose named entity is a gmeow:Place — a time/audience/register-scoped use of a toponym. Defined, NOT asserted: any NameUsage that names a Place is inferred to be a PlaceNaming (≡ gmeow:NameUsage ⊓ ∃gmeow:usageNamed.gmeow:Place), so place-naming reuses the NameUsage relator instead of minting a parallel relator (Principle 6, greenfield/no-redundancy). The reified counterpart of CIDOC-CRM's time-spanned crm:E48 Place Name / crm:E41 Appellation. Competing and historical place names coexist as co-equal PlaceNamings with no primary; superseded ones set gmeow:displayable false (Principle 10). The toponymic authority is gmeow:usageAuthority; the name's language is gmeow:nameLanguage on the bound gmeow:PlaceName (reached via gmeow:usageAppellation).
Place Type
The kind of a geographic place (country, region, city, building, room, …). Modelled as a value, not a Place subclass: the set of kinds is open-ended (GeoNames lists ~600 feature codes) and they share all of Place's structure, so a new kind is a new individual, not a new class.
Playing Technique
A technique used to play or activate a musical instrument — arco, pizzicato, prepared piano, etc. An open value vocabulary of individuals; never subclassed (Principle 9).
Pose
A frame-relative position and orientation of an object — a 6-DOF pose. A pose consists of a position (spatial coordinates in a reference frame) and an orientation (quaternion, Euler angles, heading/bearing, or a homogeneous transform matrix). Aligns by reference to IEEE 1872-2015 pos:QuantitativePose and structurally to OGC GeoPose 1.0.
Post
A seat or position that exists independently of who currently holds it — the CFO chair is not the person now in it. A Post bundles a gmeow:Role within a specific gmeow:Organization, enabling 'vacant post' and 'succession in a post' queries.
Postal Address
A contact point reachable by physical mail at a postal address. It is expressed in the postal/administrative topological reference frame (gmeow:referenceFramePostalAddress); its components below are the coordinate values along that frame's axes — the as-written surface form. The resolved, identifier-bearing geographic places are reached via gmeow:addressPlace and gmeow:containedInPlace.
Posting
A reified relator connecting a journal entry to a ledger account with a monetary amount and a posting direction (debit or credit). The atomic unit of double-entry bookkeeping.
Posting Direction
The direction of a posting in double-entry bookkeeping — a VALUE, never a subclass. Only debit and credit are seeded; the vocabulary is closed in practice but modelled as open for consistency.
Precedence Tenure
The reified, time-scoped fact that one norm took precedence over another within a normative system over an interval — 'Tier 2 overrode X until v3.5' made sayable. The StandpointTenure idiom (Principle 10): carries its interval via gmeow:duringInterval (temporal module); a withdrawn precedence is kept with gmeow:displayable false, never deleted. Use only when adoption / revision of the precedence is itself worth modelling; the common case is flat gmeow:overrides.
Privacy Notice
A human- or machine-readable privacy notice informing data subjects about the processing of their personal data — the information-object counterpart of a dpv:PrivacyNotice / schema:PrivacyPolicy. It may be attached to a RightsStatement or to the entity whose data is governed.
Procedure
A prescriptive specification — a template, recipe, protocol, blueprint, workflow definition, or pipeline spec. The plan side of the plan ⟂ execution de-conflation: an InformationObject that describes how to do something, distinct from any Execution that enacts it. The kind of procedure is a gmeow:procedureType value, never a subclass.
Procedure Step
An atomic step within a Procedure. Carries inputs, outputs, and parameters. May itself reference a subprocess Procedure via gmeow:stepEnactsProcedure. The kind of step is a gmeow:StepType value, never a subclass.
Procedure Type
The kind of a procedure — a VALUE, never a Procedure subclass. The set is open; a kind not among the seed individuals is a FRESH gmeow:ProcedureType individual carrying rdfs:label, not a new class.
Professional Relationship
An interpersonal relationship arising from work — colleagues, collaborators, a client and a provider (the reified form of hasWorkedWith).
Proficiency Level
An attained proficiency level on a gmeow:ProficiencyScale (CEFR A1–C2; Dreyfus novice→expert; NIH beginner→expert; assessed; native; heritage). Carried by gmeow:proficiencyLevel and gmeow:skillProficiencyLevel; gmeow:levelScale ties it to its scale. ILR (0–5) and ACTFL levels are added as further individuals.
Proficiency Modality
The channel a proficiency rates (speaking, listening, reading, writing, signing, comprehension, overall). A value carried by gmeow:proficiencyModality.
Proficiency Scale
A framework for rating proficiency in any competency domain — language, skill, or knowledge (CEFR, ILR, ACTFL, Dreyfus, NIH, Bloom's, SOLO, assessed, self-reported). A domain-neutral value vocabulary carried by gmeow:proficiencyScale, gmeow:skillProficiencyScale, gmeow:knowledgeProficiencyScale, and gmeow:levelScale. Minted in kernel so expertise, languages, and cognition reuse it without a cross-slice dependency cycle (Principle 6).
Profile
A closed descriptor schema for an open-but-structured facet. A Profile self-describes the properties that constitute the facet and the open value vocabularies from which their values are drawn, enabling extensibility-by-construction.
Profile Page
A web page whose principal subject is an agent — a person's or organization's profile/about page. A DEFINED class: any gmeow:WebPage whose gmeow:pagePrincipalSubject is a gmeow:Agent IS a ProfilePage (≡ gmeow:WebPage ⊓ ∃gmeow:pagePrincipalSubject.gmeow:Agent), so no manual typing is needed. Projects to schema:ProfilePage.
Programming Language
A formal language for expressing executable computation (Python, Rust, SQL-as-implemented). The first-class target of gmeow:writtenInLanguage, by which a software project declares the languages it is written in.
Prohibition
A rule that forbids the exercise of a gmeow:RightsAction over the governed asset (odrl:Prohibition).
Project
A social object representing an endeavour — an activity with purpose, participants, and duration, independent of any product, repository, or codebase. A project persists, bears identity and PIDs, and participants come and go; it is realised through events (milestones, releases, sprints), not identical to them. Modelled as an endurant (social object), not a perdurant (process).
Projection Context
The consumer or audience for which a fact is eligible to be projected — an open value vocabulary of individuals (never subclasses). Names downstream targets such as internal archives, agent memory, Wikidata, Wikipedia, or public websites. The *who* layer of disclosure control, orthogonal to sensitivity, determinacy, confidence, and granularity (Principle 9). Eligibility decisions (k-anonymity, source-independence checks) are solver-layer computations (P12); the vocabulary is the ontology deliverable.
Projection Function
An FnO function that renders canonical frame-relative content to a notation system (Principle 12).
Projection Loss
A kind of information loss incurred when canonical content is projected to a notation system. An open value vocabulary of individuals; never subclassed (Principle 9).
Prompt
A concrete prompt presented to a model in an invocation — content-addressable (gmeow:contentDigest), role-tagged (gmeow:promptRole), optionally instantiating a template (gmeow:filledFrom). Prompts are provenance: a claim is only auditable when the instruction that elicited it is recorded. The system-prompt-as-persona seam (a prompt enacting a gmeow:Persona with its registers and style guide) is the norms extension's machinery, used from instance data.
Prompt Role
An open value vocabulary of conversational prompt roles.
Prompt Template
A reusable, versioned prompt with unfilled variables — the published artifact (EvidenceSpan audit machinery ships the claim-extraction template as data, not code). Concrete prompts link back via gmeow:filledFrom.
Pronoun Set
A set of third-person pronouns a person goes by, in the five English forms (subject, object, possessive determiner, possessive pronoun, reflexive). Sex/gender INDEPENDENT and contextual. A known set is one of the gmeow:PronounSet value individuals; any other set is expressed by filling the five form properties on a fresh PronounSet instance.
Proposition
A truth-apt content — a described state of affairs that can be held true or false, the object of a doxastic attitude (gmeow:believes, gmeow:knowsThat). Existing by social convention like every description, it is a gmeow:SocialObject. A Proposition asserts nothing by itself: that an agent holds it, and with what modality, is a vantage-indexed claim (Principle 9). It is the doxastic sibling of gmeow:Goal (teleology): a belief and a goal may share the SAME proposition but differ in direction of fit — a belief has mind-to-world fit (it aims to be true to the world), a goal has world-to-mind fit (it aims to make the world true to it).
Proximity Measurement
A measurement of distance, dissimilarity, or proximity between two entities, expressed as a scalar quantity in a reference frame that declares its metric kind. The observedFeature is the entity measured from; gmeow:proximityTo names the target entity; gmeow:observationResult points to the scalar value. Computed by the solver (Principle 12), not asserted in the OWL core.
Push
The event of pushing one or more commits to a remote repository — an activity with a target repository or ref, a pusher, and a timestamp. The event type is gmeow:eventTypePush.
Quality Assessment
A reified assessment of the quality of an entity or dataset, expressed as an observation about one or more quality dimensions. The result is typically a scalar quantity (accuracy in metres, completeness as a percentage, etc.) or a categorical conformance statement, carrying unit, reference frame, determinacy, and provenance in the same bundle as every other GMEOW measurement (Principle 11).
Quality Dimension
An ISO 19157 data-quality dimension or lineage category — an open value vocabulary of individuals (never subclasses). New dimensions (e.g. a domain-specific 'semantic consistency' or 'usability') are added by minting fresh individuals, not by creating new classes (Principle 9).
Quantity
A universal scalar numeric value bundled with unit/frame, determinacy, and provenance — the synthesis of FRAME-GEN + DET-GEN + OBS (ScalarQuantity alias precedent). Equivalent to gmeow:ScalarQuantity; the domain-neutral name for the same construct. Used for temperatures, distances, counts, probabilities, masses, prices, and any other quantitative observation result. The value lives in gmeow:quantityValue; the unit/frame in gmeow:hasUnit / gmeow:hasReferenceFrame; the determinacy in gmeow:hasDeterminacy; the provenance in gmeow:isResultOf.
Question
Erotetic content individuated by its ANSWERHOOD CONDITION — the set of propositions counting as direct answers — not by a truth-condition. Existing by social convention like every description, it is a gmeow:SocialObject. A Question is neither true nor false (unlike a gmeow:Proposition) nor satisfied (unlike a gmeow:Goal): it is RESOLVED by an accepted answer. It is the erotetic sibling of gmeow:Proposition (assertoric) and gmeow:Goal (optative): the three share the gmeow:SocialObject genus and differ only in their mode of content — truth-condition, satisfaction-condition, answerhood-condition.
Question Type
The erotetic kind of a question — a closed value vocabulary spanning polar (yes/no), alternative (which-of-a-named-set), wh (who/what/where/when), why (explanation-seeking), and how (procedure-seeking): gmeow:typePolar, gmeow:typeAlternative, gmeow:typeWh, gmeow:typeWhy, gmeow:typeHow. Its members are individuals, never subclasses, and more than one may co-apply to a single question.
Reading Order
A standpoint that supplies a subjective ordering for consuming segments of a work — publication order, internal chronology, author-recommended order, or fandom order. Never canonical ontology truth; claims are annotated gmeow:accordingTo a ReadingOrder.
Realization Mode
The mode in which a musical Expression realizes its Work — a VALUE vocabulary (individuals, never subclasses). The oral-tradition guarantee requires that no shape ever mandate a notated realization.
Recording
A concrete audio manifestation of a musical work or expression — a take, master, released track, or any other fixed sound recording. Co-equal sibling of gmeow:ScoreEdition and other manifestations (Principle 9).
Recurrence Rule
A rule by which a gmeow:EventSeries repeats — weekly, every-first-Monday, annually. Carries an RFC 5545 RRULE string via gmeow:recurrenceRuleText. (= ISO-TimeML TIMEX3 type=SET with freq/quant, iCalendar RRULE, schema:Schedule, TEO periodic time interval.)
Ref
A version-control reference — the generic superclass of Branch and any other named pointer into the commit graph.
Reference Frame
A reference system (such as a coordinate system, datum, grid, or platform space) relative to which locations, coordinates, or measurements are expressed.
Reference Position
The spatial locus, observatory, timezone, or planetary body relative to which a time is expressed — e.g. an observatory longitude for local sidereal time, an IANA timezone for civil time, or a planet for planetary calendars.
Region Selector
The encoding descriptor for an image region — carries the selector type (a gmeow:SelectorType value) and the raw selector value (SVG path, pixel coordinates, mask data, RLE string, etc.). The canonical superset of W3C Web Annotation selectors, IIIF selectors, and domain-specific mask formats.
Register
A social or expressive register — the formality, intimacy, or audience-posture of an expression act (the register/persona design). The OPEN umbrella vocabulary that name registers specialize and that persona expression (norms slice) reuses: the same agent, the same norms, expressed formally in public and intimately in private. Registers are first-class value individuals with their own IRIs, labels, and definitions — never a subclass tree, never a 'primary' (Principle 9). Lives in the names core slice because register-of-address was already core here and the dependency direction (extensions reference core, never the reverse) requires the umbrella below its consumers.
Regulatory Overlay
The reified, time-scoped fact that a specific regulation applies over a place — imposed by an authority. Covers zoning, protected areas, restricted airspace, sanctions, tax/electoral districts, postal zones, civil-time zones, and similar legally-defined spatial overlays. Distinct from JurisdictionTenure (governance/sovereignty): an overlay is about a specific regulatory regime applied over a geographic area. Links to RightsStatement for the deontic rules (permissions, prohibitions, duties) that hold within it. Contested overlays coexist as multiple standpoint-indexed instances, never collapsing to a single winner (Principle 9).
Regulatory Overlay Type
The kind of a regulatory overlay (zoning, protected area, restricted airspace, sanctions, tax district, electoral district, postal zone, civil-time zone, …). A value, not a subclass: the set is open-ended and they share all of RegulatoryOverlay's structure, so a new kind is a new individual, not a new class (Principle 9).
Relay Hop
One hop in a message's delivery path, recorded by a Received header: a relaying server, the host it received from, a server timestamp, and the protocol used.
Release
A software release — an event that produces a versioned software product, typically associated with a tag, a DOI, and one or more distribution artifacts. The event facet of the five-facet model; a release is an occurrence, not the product itself.
Reminder
A reminder associated with an event — a trigger (offset or absolute time) and an action (display, email, audio).
Reminder Action
The action to take when a reminder fires — a VALUE vocabulary aligned to iCalendar ACTION, never a subclass.
Repository
A version-control repository — the location/hosting facet of a software project. Holds source code history, branches, tags, and refs. Distinct from the project (endeavour), the product (work), the codebase (content), and the history (events). Aligned to Software Heritage Origin and ForgeFed Repository by reference.
Repository Type
The version-control system of a repository — a VALUE vocabulary (individuals, never subclasses). The set is open; a new VCS is a fresh individual, not a new class.
Retrieval Event
One retrieval against a vector index: the query, the index queried, and the chunks returned — the answer to 'why did the model see this passage?'. An agent-memory recall is a RetrievalEvent too (the core MemoryItem doctrine's read operation). Per-chunk relevance rides gmeow:retrievalScore statement annotations on each gmeow:retrievedChunk triple.
Review
A code review or peer review of a merge request or commit — an InformationObject carrying review text, approval state, and requested changes. The reviewing activity itself is a gmeow:Event with gmeow:Participations.
Rights Action
The kind of action a rights rule regulates — a VALUE, never a rule subclass. The set is open (ODRL's action vocabulary + CC REL); an action not among the seed individuals is a FRESH gmeow:RightsAction individual carrying rdfs:label. Pointed at by gmeow:ruleAction.
Rights Statement
A reified, machine-readable statement of the rights situation of an entity — an observation in the universal claim stack (observation-spine bridge). Who may do what with it, under what licence, with what copyright, attributed to whom, over what term. The canonical superset of an ODRL Policy / Set: it bears gmeow:Permission, gmeow:Prohibition and gmeow:Duty rules and points at the asset it governs via gmeow:statementAbout (the observedFeature). Promote a flat gmeow:hasLicense / gmeow:hasCopyright to a RightsStatement only when the deontic rules are needed.
Rights Type
A kind of intellectual-property right — an OPEN value vocabulary (copyright, trademark, patent, industrial design, trade secret, related rights, moral rights, database right, plant breeders' rights), linked to Wikidata / WIPO.
Risk Factor
The umbrella category of things a mitigation can be set against — causal links (a bowtie barrier on the chain) and hazards (a control at the source). Exists as a NAMED class so gmeow:mitigationCounters carries a generator-visible range instead of an anonymous union (the IntentionalMoment precedent) and so the relator-arity gate can see the mediation end. Never instantiated directly.
Role
A function or position an agent plays in some context, such as a job title or organizational role. A gufo:RoleMixin played within a gmeow:Membership, never a subclass of the agent who plays it (Principle 9 — roles are values, not kinds of person).
Role In Narrative
The reified, interpretive fact that a character bears a narratological role RELATIVE TO A SCOPE — protagonist of the trilogy, of one book, of one chapter are different claims. Vantage-indexed through the statement layer; ensemble works carry coexisting protagonist relators and NO primaryProtagonist exists or ever will (Principle 9). Flat shortcut gmeow:hasNarrativeRole for the 80% single-work case.
Romantic Orientation
A person's SELF-ASSERTED romantic orientation — the pattern of their romantic attraction — as a reified facet pointing (via gmeow:romanticOrientationValue) to an open gmeow:RomanticOrientationValue. A SEPARATE axis from sexual orientation (split-attraction model); the two are mutually independent (e.g. asexual yet biromantic).
Romantic Orientation Value
A pattern of romantic attraction — a VALUE pointed at by gmeow:romanticOrientationValue, never a subclass. Kept separate from sexual orientation (split-attraction). Open: a fresh individual with rdfs:label when none is seeded.
Route
A traversable path through a graph of connected entities — a named, typed sequence of linked nodes with a defined start and end. Models transport lines, network paths, citation chains, social paths, and dependency chains. The actual path geometry, ordering, and cost are computed by the solver layer (Principle 12), not asserted as triples.
Route Kind
The kind of a route — transit line, flight path, walking path, citation chain, network path, social path, dependency chain. An open value vocabulary (individuals, never subclasses) per Principle 9.
RSVP Status
The RSVP response status as asserted by an invitee — a VALUE vocabulary, distinct from InvitationStatus so that organizer and invitee claims can coexist (Principle 9).
Rubric
A norm for judging — a reified evaluation framework whose criteria, poles, scales, and anchors are first-class content. Being a Norm, a rubric names its issuer (no anonymous evaluation standards), may be overridden, and carries authority within its issuing system. Applying a rubric is solver work; the results come back as vantage-indexed Assessments (Principle 12). Member criteria attach via gmeow:hasCriterion (⊑ gmeow:hasPart).
Rule
The abstract base of a deontic rule in a rights statement — it binds a regulated gmeow:RightsAction to an optional target asset and assignee. Specialised by gmeow:Permission, gmeow:Prohibition and gmeow:Duty (the ODRL rule trio).
SLSA Level
The SLSA supply-chain level for build provenance — a VALUE vocabulary (individuals, never subclasses). Levels 1–4 correspond to the SLSA specification's incremental integrity guarantees.
S/MIME Signature
An S/MIME signature (RFC 8551) over a message, bound to an X.509 certificate.
Scalar Quantity
A scalar numeric value with a unit, determinacy model, and granularity — the entity-valued wrapper for literal observation results (temperatures, distances, counts, probabilities). Keeps gmeow:observationResult uniformly entity-valued: the scalar literal lives here, not on the observation directly.
Scene Graph Edge
A reified spatial or semantic relationship between two image regions — a gufo:Relator mediating a subject region, an object region, a relation type, and a confidence. The canonical form for scene-graph assertions; aligns by reference to Visual Genome and OVSR relation strings.
Scene Relation Type
The spatial or semantic relation in a scene-graph edge — a VALUE vocabulary (individuals, never subclasses). leftOf, rightOf, above, below, inside, touching, near, farFrom, sameAs, partOf, holding, wearing, riding, eating, playing are examples; the set is open. Aligns by reference to Visual Genome and OVSR relation strings.
Schedule Exception
An exception to a recurring event schedule — a cancellation or rescheduling of a specific generated occurrence. A relator mediating the schedule, the original date, and optionally a replacement event. Retained with displayable false rather than deleted (Principle 10).
Schenker Level
An open value vocabulary of Schenkerian structural levels. Never subclassed (Principle 9).
Score Anchor
A pinned score range with its meaning and exemplars — 'range 0.8–1.0 means the text embodies the covenant, as in THIS passage'. Anchors are the rubric's calibration content; interpolation between anchors is solver work (Principle 12).
Score Edition
A concrete notated manifestation of a musical work or expression — a printed score, engraving, MusicXML file, MEI document, or any other symbolic edition. Co-equal sibling of gmeow:Recording (Principle 9).
Score Scale
A numeric scale for assessments — minimum, maximum, optional step. Scale arithmetic (normalization, conversion between scales) is solver work (Principle 12).
Script Language Attribution
A standpoint-scoped claim assigning a language, writing system, or notation system to an inscription. Handles disputed, uncertain, and undeciphered cases: an undeciphered inscription may carry an attribution to a NotationSystem with low confidence and determinacy = disputed, while competing palaeographic classifications coexist as separate attributions (Principle 9). Follows the universal Observation + Relator pattern.
Script Role
The role a writing system plays within a language's mixed orthography (primary, logographic content, syllabic grammar, loanword, transliteration, liturgical, historical, decorative). A value carried by gmeow:scriptRole.
Segment Kind
The granularity or functional role of a MusicalSegment, drawn from an open value vocabulary of individuals. Never subclassed (Principle 9).
Segment Transformation
A reified relator binding a source MusicalSegment, a target MusicalSegment, a transformation type, and an optional parameter. The AI-analysis backbone: assertions may come from composer text or from an analysis standpoint via the statement layer (Principles 2, 9, 14).
Selector
A pinpoint reference into a cited creative work — a page number, text position, text quote, or generic locator. Replaces the retired gmeow:Citation (which collided with scholarly citation). A specialization of gmeow:EvidenceSpan: a citation selector is an anchored target within a cited work. Coordinated with EvidenceSpan audit machinery's EvidenceSpan mechanism and reused by annotation target span's annotation target span.
Selector Type
The encoding kind of a region selector — a VALUE vocabulary (individuals, never subclasses). SVG path, pixel rectangle, fractional rectangle, polygon, RLE mask, COCO mask, DICOM-SEG mask, and Web Annotation fragment are examples; the set is open.
Seniority Level
The seniority or rank of an employment — a VALUE, never an Employment subclass. The set is open; a level not among the seeds is a FRESH gmeow:SeniorityLevel individual carrying rdfs:label. Pointed at by gmeow:employmentSeniority. Orthogonal to employment type and role.
Sensitivity Level
A privacy-sensitivity classification for a value — an open, ordered value vocabulary (public ≺ internal ≺ confidential ≺ restricted ≺ sensitive personal). The explicit facet that drives disclosure-control decisions: a value marked sensitive personal may be coarsened or withheld at projection time under a consent guard. Orthogonal to determinacy, confidence, and granularity (Principle 9). The sensitivity-to-coarsen trigger is a solver concern (P12).
Sensor
An agent that produces observations by responding to a stimulus — a physical device, a software process, or a biological perceiver. The observer in a sensory observation; the vantage of a SensoryObservation may be a Sensor, a person, or an organization. Co-equal: no sensor is privileged as the 'primary' observer (Principle 9).
Sensor Platform
A physical entity that hosts one or more sensors — a weather station, a satellite, a buoy, a drone, a vehicle, or a building-mounted instrument. The platform is situated at a place and carries sensors that observe properties of the environment. Distinct from the Sensor itself (the observing agent) and from the Place (the location).
Sensory Environment
Ambient perceivable conditions at a specific location and time — the ensemble of physical properties that can be measured by instruments or perceived by observers. A SensoryEnvironment is reified as a first-class entity (not merely a property bag) so that measurements and perceptions about it can carry provenance, confidence, temporal scope, and standpoint indexing. Measured conditions are expressed as CoordinateMatrix values in measurement reference frames; perceived conditions are standpoint-indexed values in MentalReferenceFrames (Principle 9: co-equal facets, no privileged representation).
Sensory Modality
The sensory channel or domain through which an environment property is measured or perceived — a value vocabulary (individuals, never subclasses). Distinguishes visual, auditory, olfactory, gustatory, tactile, thermal, air-quality, and other environmental sensing channels. A single environment or observation may span multiple modalities (Principle 9: co-equal, non-functional).
Sensory Observation
An observation produced by a sensor or sensory apparatus reading a physical property of the environment. Specialises Observation with sensor-specific properties (sensory property, sensor platform, sampling feature).
Sensory Perception
A standpoint-indexed perceived value about a SensoryEnvironment — a subjective claim made by a perceiver (vantage) about ambient conditions (observedFeature), yielding a result in a MentalReferenceFrame. A SensoryPerception is a StandpointClaim specialised to the sensory domain: the vantage is the perceiver, the observedFeature is the SensoryEnvironment, and the observationResult is the perceived value (a ScalarQuantity, categorical individual, or structured percept descriptor). Competing perceptions coexist without collapse (Principle 9); superseded perceptions are suppressed, never deleted (Principle 10).
Sensory Quantity
The scalar numeric result of a sensory observation — a value with unit, determinacy, and granularity. Equivalent to gmeow:ScalarQuantity (following the ScalarQuantity alias precedent); the name 'SensoryQuantity' is the domain-specific label for the same construct in the sensor/observation stack.
Sequence Coordinates
Frame-relative coordinates on a biological sequence: a start position, an end position, and a strand orientation, all expressed relative to an explicit reference assembly (Principle 11).
Sequence Feature
A feature or annotation on a biological sequence — a range with start, end, strand, and type, expressed in a reference assembly frame. The first-class entity that carries the coordinates and type; linked to a BiologicalSequenceLocation via gmeow:hasSequenceFeature.
Sequence Feature Type
The kind of a sequence feature (gene, exon, intron, CDS, SNP, chromosome, etc.). A value, not a subclass: the set is open-ended (Sequence Ontology lists ~2000 types) and they share all of SequenceFeature's structure, so a new kind is a new individual, not a new class (Principle 9).
Serial Installment
A single issue, episode, or chapter of a serial creative work — a comic issue, TV episode, magazine issue, or serial chapter. An out-of-universe publication artifact distinct from the narrative frame it sources. A specialization of gmeow:Manifestation.
Serial Work
An ongoing authored work released over installments — a web serial, comic series, or magazine. A specialization of gmeow:Work.
Service
A system that provides one or more functions — a web API, hosted application, or online service. A specialization of gmeow:Work in the schema.org / creative-work sense (schema:Service).
Service Offering
A service an agent provides — consulting, support, hosting (project homepage and language). Distinct from gmeow:Service (the documents-slice creative-work sense); this is the commercial service. Its kind is an open gmeow:ServiceType value; projects to schema:Service.
Service Status
The liveness status of an online service — a VALUE vocabulary (live, shut-down, …); open set.
Service Type
The kind of a service offering — a VALUE vocabulary (individuals, never subclasses); open set (consulting, hosting, support, …).
Set Class Label
An open value vocabulary of pitch-class set labels (Forte names and successors). Never subclassed (Principle 9).
Severity Level
The graded severity of a cascade or hazard — an OPEN, ordered value vocabulary (catastrophic ≻ severe ≻ moderate ≻ minor; deployments add grades — negligible, critical, FMEA 1–10 bands — without schema change, Principle 9), the kernel GranularityLevel pattern (fourth use). gmeow:moreSevereThan is transitive ON LEVELS ONLY. Terminology anchored to ISO 31000 / IEC 60812 in docs, never axioms; what a grade DEMANDS in response is the norms extension's business, plugged in via Mitigation.
Sex Assigned at Birth
A recorded sex-assigned-at-birth value pointed at by gmeow:sexAssignedAtBirth — a VALUE, never a subclass. Deliberately coarse and inclusive (incl. intersex); finer sex-characteristic detail is an optional free-text gmeow:intersexVariation note, not a clinical taxonomy.
Sexual Orientation
A person's SELF-ASSERTED sexual orientation — the pattern of their sexual attraction — as a reified facet pointing (via gmeow:sexualOrientationValue) to an open gmeow:SexualOrientationValue. A SEPARATE axis from romantic orientation (split-attraction model) and from gender identity/expression; nothing infers one from another.
Sexual Orientation Value
A pattern of sexual attraction — a VALUE pointed at by gmeow:sexualOrientationValue, never a subclass. Open: an orientation not seeded here is a fresh individual with rdfs:label.
Signature Scheme
The cryptographic signature scheme used — a value vocabulary (individuals, never subclasses). Distinct from gmeow:KeyScheme: a key scheme names the key format (OpenPGP, X.509), while a signature scheme names the algorithm (RSA-SHA256, Ed25519).
Site Type
The purpose of an organization's site — headquarters, branch, registered office, etc. A value, not a subclass.
Skill
A competency or ability an agent possesses — a knowledge, ability, or expertise that can be applied to perform a task. Occupation-independent; aligned to esco:Skill by reference.
Skill Proficiency
A reified, leveled proficiency of an agent in a skill — the gufo:Relator binding {agent} × {skill} × {level on a scale} × {interval}, mirroring languages' gmeow:LanguageProficiency. Mint one per (agent, skill) so per-skill levels coexist; the flat gmeow:hasSkill relation states that an agent has a skill, this relator adds the level and the scale.
Smart Contract
A deployed program on a blockchain or distributed ledger, identified by a contract address.
Social Object
An entity that exists by virtue of social convention, collective acceptance, or sustained narrative practice — a myth, an urban legend, an agreement, a standpoint, or a socially-constituted institution. Distinct from PhysicalObject (material) and overlapping with InformationObject (a myth is both social and informational). No disjointness with InformationObject is asserted so that socially-sustained narratives may carry information content without identity clash.
Software Agent
A software process or autonomous program that acts on behalf of a person or organization.
Software Name
An appellation borne by a software project or product — a project name, product name, codename, or package name. Carries its own gmeow:nameLanguage and gmeow:nameScript so co-equal multilingual names are separate first-class objects.
Software Product
A software work as an intellectual creation — the design, functionality, and behaviour of a program, library, or application, independent of any particular source repository, release event, or concrete artifact. The product facet of the five-facet model; distinct from the project (endeavour), the codebase (content), the repository (location), and the history (events). A specialization of gmeow:Work (the WEMI spine).
Software Project
A project whose endeavour is the collaborative development of software. The social object facet only — distinct from the software product, the source codebase, the version-control repository, and the commit history. Re-parented from gmeow:Work to gmeow:Project (Principle 6: greenfield de-conflation).
Source Directory
A content-addressed subdirectory within a source tree — a named container of files and nested directories. A specialization of gmeow:SourceTree for nested structure.
Source File
A content-addressed source file — a named blob of text or binary content within a source tree. Aligned to Software Heritage Content and git blob objects by reference.
Source Independence
The independence of a source from the subject it covers — a value vocabulary (individuals, never subclasses). Distinguishes sources that are editorially independent from those originated or controlled by the subject. This axis is about notability eligibility, not factual truth (Principle 1).
Source Node
A content-addressed node in a source graph — the common kind for all objects that participate in a versioned source tree (files, directories, and recursive tree structures). Aligned to the git object model and Software Heritage object graph by reference.
Source Role
The anti-rigid role of being a source — borne by a gmeow:CreativeWork when it is used as evidence for a claim. A thing is only contingently a source; the same work may be evidence for one claim, the subject of another, and a work in its own right. Source-hood is primarily relator-mediated (via CitationAct), but SourceRole provides a named handle when needed.
Source Tier
The bibliographic tier of a source — primary, secondary, or tertiary — a value vocabulary (individuals, never subclasses). This is the standard source-tier axis applied to notability assessment (cf. WP:GNG).
Source Tree
A content-addressed directory tree of source code — the recursive Merkle structure that represents a snapshot of a project's files and subdirectories at a point in time. Aligned to Software Heritage Directory and git tree objects by reference.
Spatial Aggregation
A measurement that aggregates entities located within a spatial region, yielding a scalar result such as a count, density, or average. The aggregation region is the observedFeature; the result is a ScalarQuantity. The actual computation is performed by the solver layer (Principle 12), not materialised as asserted triples in the OWL core.
Spatial Bin
A place that serves as a spatial bin in an aggregation grid — a generated region used to partition space for statistical summarisation. Its geometry defines the bin boundary; its aggregation result is a SpatialAggregation.
Spatial Coordinates
A set of coordinate values representing a position in a specific coordinate reference frame.
Spatial Measurement
A measurement that assigns a spatial property — coordinates, geometry, pose, or spatial extent — to a feature of interest. The parent of CoordinateObservation and other spatial measurement specialisations. Realises the spatial side of Principle 3 (Observation ≡ Measurement ≡ Standpoint).
Spectrum
A first-class information object representing a partial list or recording-region spectrum. Spectra are the source material from which pitch collections may be derived by a solver (fnSpectrumToPitchCollection) — the canonical content of spectralism (Principle 12).
Standpoint
A named perspective / frame within which claims are held true — a state's official position, a community's usage, an editorial or historiographic point of view. Minted only when the frame needs its own identity and labels; often a bare gmeow:Agent (a polity, an organization) suffices as the value of gmeow:accordingTo instead. Standpoints form a poset under gmeow:sharpens, topped by gmeow:universalStandpoint.
Standpoint Claim
An observation made from a specific standpoint or frame — an assertion, denial, or qualified position that a proposition holds. Realises the standpoint side of Principle 3 (Observation ≡ Measurement ≡ Standpoint). The vantage is the standpoint; the observedFeature is the proposition or fact being claimed; the observationResult is the modality (unequivocal, probable, conceivable, refuted).
Standpoint Modality
The belief value a standpoint assigns a proposition — a closed value vocabulary spanning the Standpoint-Logic □/◊ and the CRMinf belief value (true/false/probable/possible), plus the Frankfurt bullshit modality: gmeow:unequivocal, gmeow:probable, gmeow:conceivable, gmeow:refuted, gmeow:bullshit. Absence of a value is read as unequivocal.
Standpoint Tenure
The reified, time-scoped fact that a standpoint held a particular position over an interval — recognition granted in 2008 and withdrawn in 2030 is an opened-then-closed tenure, never a deletion (Principle 10). Use only when the adoption / withdrawal of the position is itself worth modelling; the common case is a bare gmeow:accordingTo annotation. Carries its standpoint-time interval via gmeow:duringInterval (temporal module). A StandpointTenure generates a gmeow:standpointClaim observation. The tenure is the time-scoped fact; the claim is the observation of that fact. The tenureStandpoint maps to the claim's vantage; the tenurePosition maps to the claim's observedFeature.
Step Parent-Child
A parent-child relationship through marriage to a biological/adoptive parent.
Step Type
The kind of a procedure step — a VALUE, never a ProcedureStep subclass. The set is open; a kind not among the seed individuals is a FRESH gmeow:StepType individual carrying rdfs:label, not a new class.
Storage Location
A locus where digital objects reside — a cloud-storage folder, an object-store bucket, a filesystem path, a content-addressed store, or a physical disk. Its medium is a value (gmeow:storageMedium); a physical device may sit at a geographic gmeow:physicalPlace.
Storage Medium
The kind of medium a storage location uses (cloud service, local filesystem, object store, content-addressed store, physical disk, removable media). A value, not a StorageLocation subclass: the kinds share the same structure (path, service, holder, physical place).
Strand Orientation
The strand direction of a feature on a double-stranded biological sequence (forward / Watson, reverse / Crick, or both). A value, not a subclass: the set is closed and they share the same structure.
Stream
A time-ordered sequence of observations or samples produced by a sensor or platform over a time interval. The ordering of samples is implicit via their individual timestamps, not asserted as a list structure (Principle 12). A stream is the canonical source from which a continuous trajectory may be derived by the solver layer.
Style Guide
The voice payload of a persona or register — prose whose REGISTER IS THE CONTENT. The prose-voice doctrine (gap analysis): voice documents attach byte-perfect via gmeow:exemplifiedBy (content-digested Documents carrying gmeow:hasAboutness gmeow:aboutnessEnacts — the document does not describe the voice, it IS the voice), never shredded into pseudo-quantified style triples. Style dimensions, when stated, are prose.
Summary
A condensed account derived from a source information object (often machine-generated), linked to its source by gmeow:wasDerivedFrom. A lossy projection of its source: the source remains canonical and the summary is the reduced view.
Support Polarity
The closed three-value polarity of an evidence span toward its claim.
Symbolic System
A system of symbols, signs, or conventions used for communication, representation, or expression. Broad umbrella covering notation systems, gesture systems, emoji conventions, platform conventions, and other non-linguistic symbol systems. NOT a language by default; a standpointed claim may classify a symbolic system as a language (Principle 9).
Symbolic System Kind
The domain or kind of a symbolic or notation system — a value, never an Entity subclass. The seed list is an anchor, not a fence; new domains may introduce further kinds without ontology modification.
Tag
An open, user-minted tag — an information object whose identity is its IRI and whose surface form is carried by rdfs:label. Synonyms are multiple labels; homonyms are different IRIs. Coreference is done in data, never by collapsing into one. A tag is NOT a type (it carries no inferential weight over rdf:type) and NOT a property bag — no datatype value property is asserted on it. Part of the universal tagging building block that keeps folksonomy, aboutness and typing as three orthogonal axes.
Tag Scheme
A namespaced set of tags — a project vocabulary, a personal tag bucket, or a controlled vocabulary. Multi-tenant: many schemes coexist, and a tag may belong to zero or more schemes (gmeow:tagInScheme). The counterpart of skos:ConceptScheme and schema:DefinedTermSet.
Tagging
A reified tagging act — a gufo:Relator mediating a tagged resource, a tag, a tagger, and optionally a scheme and time interval. Bears provenance (gmeow:wasAttributedTo), confidence (gmeow:confidence), and suppression (gmeow:displayable false for retraction without deletion — Principle 10). Structurally the NameUsage/IdentityFacet idiom wearing a different hat, inheriting time-scoping, confidence-weighting, and retract-without-delete for free. The canonical form when the act of tagging must itself be a node; the flat shortcut is gmeow:hasTag.
Task
A to-do or task — an event with a due date, status, priority, and optional recurrence-until-done. A subtype of gmeow:Event so it participates in the full event spine: temporal placement, location, participation, and scheduling. The kind of task is a gmeow:eventType value, never a subclass (Principle 9).
Task Status
The status of a task — a VALUE vocabulary, never a Task subclass.
Teaching
A reified teaching relation — one teacher, one or more learners, and the subject taught, mediated as a gufo:Relator so the roles, period, confidence, and evidence of instruction are first-class (the gmeow:Participation / gmeow:KnowledgeProficiency relator idiom). The being-taught face of learning: a learner's gmeow:LearningEvent of variety gmeow:learningBeingTaught participates in a gmeow:Teaching, which carries who taught it (gmeow:teacher) and what was taught (gmeow:subjectTaught). The teacher must differ from the learner — a closed-world rule enforced by gmeow:TeachingShape (SHACL), not a DL axiom.
Telephone Number
A contact point reachable by telephone.
Tempo Map
A TimeMapping from a musical-time frame to a clock-time frame, expressed piecewise as constant, linear ramp, curve, or measured segments. Tempo is a frame mapping, not a single number, unless it happens to be one (Principle 11).
Tempo Map Kind
The curve shape of a TempoMap or segment — constant, linear ramp, curve, or measured. A value vocabulary of individuals; never subclassed.
Tempo Map Segment
One piece of a piecewise TempoMap — a span together with a tempo-map kind (constant, linear ramp, curve, measured) and the segment-level ratio or expression data needed by the solver (Principle 12).
Temporal Frame
A reference system for expressing time — the temporal counterpart of gmeow:ReferenceFrame. Decomposed into a TimeScale, an optional CalendarSystem, and an optional ReferencePosition. Every crisp instant or interval is asserted relative to a TemporalFrame (Principle 11).
Temporal Measurement
A measured assignment of a date or age to an entity or sample, carrying the method, uncertainty, and determinacy. Now a subclass of gmeow:Measurement (and therefore gmeow:Observation), realising Principle 9: the measurement is a standpoint-indexed claim (vantage + observedFeature + observationResult), not ground truth.
Temporal Precision
The granularity to which an event's time is known — day, month, year, decade, or circa. A value carried by gmeow:temporalPrecision; pairs with gmeow:earliestStart / gmeow:latestEnd to express a fuzzy date without abandoning DL-clean xsd:dateTime base triples.
Text Direction
The writing direction of a writing system (ltr, rtl, vertical, boustrophedon, non-linear, contextual). A value carried by gmeow:textDirection.
Text Extraction
The text content extracted from a source object (e.g. a PDF attachment), linked to its source by gmeow:wasDerivedFrom. A faithful (ideally verbatim) rendering of the source's textual content, distinct from a gmeow:Summary, which condenses and is therefore lossy.
Thread
A conversation: a set of messages related by reply/reference chains.
Timbre Descriptor
A perceived timbre quality applied to a ToneEvent — bright, dark, breathy, gritty, hollow, etc. A value vocabulary of individuals; never subclassed (Principle 9). Contested descriptors are coexisting standpoints, each in its own observation.
Time Interval
A bounded stretch of time, optionally open-ended, delimited by a start and/or end instant.
Time Mapping
A declared mapping between two musical time frames or spans. Tuplets, tempo canons, and tempo maps are kinds of TimeMapping; their arithmetic is solver-evaluated, never reasoner-asserted. MetricModulation and GrooveProfile are modeled as separate constructs (Principles 4, 12).
Time Mapping Kind
The kind of a TimeMapping — tuplet, tempo canon, tempo map, or unsynchronized ad-lib span. A value vocabulary of individuals; never subclassed.
Time Scale
The atomic progression of time — TAI, TT, UTC, GPS, UT1, TDB, etc. A time scale is independent of any calendar or geographic reference position.
Time-Scoped Relation
A reified relationship that holds only over a particular time interval — the base for residence, tenure, and membership-over-time situations.
Time Zone
A time zone identified by an IANA tzid (e.g. America/Toronto). Used by calendars, schedules, and events to express civil time relative to a geographic reference position.
Tone Event
The one structural subkind of MusicalSegment — an atomic sounding unit with pitch content (a PitchValue, a PitchTrajectory, or unpitched), a duration via segmentSpan, and optional parameters such as dynamics and articulation.
Tool Call
One invocation of a tool by an agent: the tool agent (gmeow:usedTool), the requesting model invocation when known (gmeow:calledByInvocation), and the verbatim arguments/result payloads. The agent's actions join the same provenance graph as its claims — an entity the call produced links back via gmeow:wasGeneratedBy (no forward output property, Principle 5), so 'which tool, called by which invocation, with what arguments?' is answerable after the fact. The ModelInvocation idiom one level down.
Trademark
The reified trademark right over a mark — binding the mark, its holder, the registration number and the ™/®/status value. Aligned (by reference) to schema:Brand, the WIPO trademark vocabulary and Wikidata.
Trademark Status
The registration status of a trademark — a VALUE: unregistered (™), registered (®), pending, expired, or cancelled. Open vocabulary.
Trajectory
A continuous path of motion representing the space-time history of a moving entity.
Transaction Status
The status of a financial transaction — a VALUE, never a subclass. Open vocabulary; seeds in Phase B.
Transaction Type
The kind of a financial transaction — a VALUE, never a subclass. Open vocabulary; seeds in Phase B.
Transform Codec
A payload transform from the durable GTS catalog (spec §8): a named, stackable codec separating structure durability (CBOR + the spec, forever) from density and confidentiality (swappable codecs). An OPEN value vocabulary tagged by gmeow:codecClass.
Transformation Type
The kind of segment transformation — transposition, inversion, retrograde, augmentation, diminution, phase shift, reaccentuation, octave displacement, timbre reorchestration, spectral compression, ornamentation, quotation, reduction. A value vocabulary of individuals; never subclassed (Principle 9).
Transliteration Scheme
A named transliteration/romanization/transcription system (Hepburn, Pinyin, ISO 233, IPA, …). A value carried by gmeow:transliterationScheme; the major schemes are catalogued as FnO functions in the projection layer (projections/transforms.fno.ttl).
Transparency Log Entry
An append-only registry evidence record such as a Rekor entry, SCITT receipt, certificate-transparency log entry, or timestamp/notary log entry. Proves inclusion at a point in time, not correctness (Principle 1).
Traversal Constraint
Mobile form as data: a set of fragments, allowed-successor links (mayFollow), selection rules, and termination rules interpreted by a solver. Graph reachability and termination are solver work; no DL chain axiom is ever asserted over mayFollow (Principles 4, 12).
Tree Entry
A named pointer within a source tree — a file or directory entry carrying a name, a file mode, and a reference to a Blob or SourceTree. Corresponds to a single line in a git tree object. Not content-addressed on its own; it acquires identity only as part of the tree that contains it.
Trust Assertion
A reified, perspectival assertion that one agent (the trustor) trusts another (the trustee), optionally as an introducer to a given depth — the OpenPGP owner-trust notion. Its validity window is carried with gmeow:validFrom/validUntil.
Tuning System
A reference frame for musical pitch values — a named system that defines how pitch degrees, frequency ratios, or cents are interpreted. 12-EDO is one TuningSystem individual among many (Principles 9, 11).
Tuning System Kind
The kind of a tuning system, drawn from an open value vocabulary of individuals (equal division, just intonation, well temperament, instrument-relative, etc.). Never subclassed (Principle 9).
Usage Attestation
An evidence node recording that a lexical form, reading, inscription, symbol, construction, or usage was observed in a source or context. Evidence, not truth: an attestation records that something was seen, not that a proposed interpretation is correct (Principle 12). Follows the LanguageState / KinRelationship pattern as an Observation + Relator. Mediates between an attested form, a source, a context, and optionally a time interval.
Utilization
A measurement of the ratio of current occupancy to maximum capacity at a location, typically expressed as a ratio (0–1) or percentage. The location is the observedFeature; the result is a ScalarQuantity. Computed by the solver layer (P12) from capacity and occupancy measurements, not asserted directly in the canonical core.
Vector Index
A built retrieval structure over a corpus's embeddings — the artifact a RetrievalEvent queries. Carries its algorithm (gmeow:indexAlgorithm), parameters (verbatim, for reproducibility), and metric; its build provenance rides the EXISTING gmeow:wasGeneratedBy, tying index contents to the corpus state (contentDigest) at build time.
Verification Activity
An activity that checks a signature, attestation, artifact, or ledger inclusion proof — performed by a verifier agent or software. The outcome is a gmeow:VerificationResult, not a global truth assertion.
Verification Result
An information object recording the outcome of a verification activity — verified, failed, unverified, expired, revoked, policy-failed, finality-pending, etc. A verification result is an observation output, not an axiom of correctness (Principle 12).
Verification Status
The outcome status of a verification result — a value vocabulary (individuals, never subclasses).
Version Membership
A reified, standpoint-scoped claim that a concrete entity belongs to a version set with a particular role and/or scale — an observation in the universal claim stack (observation-spine bridge). Mediates between an entity (versionMember), a version set (versionSet), and an optional role/scale asserted by an authority (membershipAuthority / vantage). Mint one VersionMembership per (entity, versionSet, role, authority) tuple; when a role changes over time, close the old membership's interval or mint a fresh one — never overwrite (Principle 10). Inherits confidence, displayable, and temporal scope from Observation.
Version Role
A role or status that an entity holds within a version set according to an authority — a VALUE, never an Entity subclass. Standpoint-scoped: 'latest' according to a package registry may differ from 'latest' according to a downstream mirror. The seed list is an anchor, not a fence.
Version Scale
The magnitude scale of a version change — a VALUE, never an Entity subclass. Used for SemVer-style classification and analogous schemes in non-software domains.
Version Set
A first-class information object representing a version family or release lineage — the set of all concrete artifacts that are versions of a common stable entity. A VersionSet is an InformationObject (a kind of Entity) so it can carry identifiers, provenance, and authority links. Examples: the lineage of a software project, the edition chain of a book, the variant family of an email thread, the DOI concept record.
Virtual Location
A non-geographic location reachable online — a video-conference room, chat space, metaverse room, website, or social media page. The specific kind is given by gmeow:virtualLocationType (a value), not a subclass. Has network addresses (gmeow:hasNetworkAddress) and an access URL (gmeow:accessUrl) rather than geographic coordinates.
Virtual Location Type
The kind of a virtual location (video conference, chat space, metaverse room, website, social media page, …). A value, not a subclass: the set is open-ended and they share all of VirtualLocation's structure, so a new kind is a new individual, not a new class (Principle 9).
Voice
A continuity strand binding MusicalSegments together; may host its own MusicalTimeFrame, TuningSystem, and MetricStructure. The carrier for polymeter, tempo canons, aleatoric boxes, and per-voice tuning/time frames (Principle 11).
Wallet Scheme
The blockchain or cryptographic scheme of a wallet — a VALUE, never a subclass. Open vocabulary.
Web Page
A page on the web identified by a URL — a concrete published artifact. A specialization of gmeow:Manifestation.
Web Site
A web site — the published collection of web pages served under one identity (a domain, a project site, a personal homepage). A specialization of gmeow:Manifestation; its pages belong to it via gmeow:pageOfSite.
Work
A distinct abstract intellectual or artistic creation, independent of any language, notation, edition, or copy — the story, the composition, the visual conception. The most abstract tier of the WEMI spine; realized through one or more gmeow:Expression. Identity changes when the creative content itself differs.
Writing System
A first-class system for visually or tactilely representing language — a script: Latin, Han (kanji), Hiragana, Katakana, Arabic, Braille, or a bespoke conlang/AI script. Carries gmeow:scriptCode (ISO 15924 when one exists, else a bespoke identifier), a type (gmeow:writingSystemType) and a direction (gmeow:textDirection). Bound to the languages that use it — co-equally and simultaneously — through gmeow:WritingSystemUsage; bespoke and non-linear scripts (Ithkuil) are first-class.
Writing System Type
The structural kind of a writing system (alphabet, abjad, abugida, syllabary, logographic, featural, ideographic, pictographic, non-linear, mixed). A value carried by gmeow:writingSystemType.
Writing System Usage
A reified, role- and period-scoped use of a writing system by a language — the gufo:Relator binding {language} × {writing system} × {role} × {period}, mirroring names' gmeow:NameUsage. Lets Japanese co-mingle Han (logographic content), Hiragana (syllabic grammar), Katakana (loanwords) and Latin (transliteration) co-equally, and models script changes over time (Turkish Arabic→Latin, 1928) via the usage's validity. Mint one usage per (language, writing system, role) tuple.
