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.


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.


The polarity of an accessibility assertion — feature (positive), barrier (negative), or limited (partial).


An interpersonal relationship of social acquaintance — agents who have met and know one another (the reified form of hasMet).


Something that occurs over a period of time and acts upon or with entities — creating, transforming, using, or attributing them.


The reified, time-scoped fact that an agent held a contact point (e.g. an email address) over a particular interval.


A parent-child relationship established by adoption.


An entity that can act, bear responsibility, and enter into agreements: a person, an organization, or a software agent.

closeMatch=ladm:LA_Party closeMatch=wd:Q24229398 equivalentClass=foaf:Agent equivalentClass=prov:Agent relatedMatch=sosa:Platform skos:broadMatch=sosa:Sensor


The kind of statistical aggregation applied to a spatial region — a value vocabulary (individuals, never subclasses).


A mutual understanding between two or more agents that creates obligations or rights, reified as a relator connecting its parties.


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.


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'.


A written work published in a periodical, blog, or scholarly venue.


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'.


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.


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).


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.


The policy or framework under which an attestation was issued — a value vocabulary (individuals, never subclasses). Open-ended; specific policies are minted as needed.


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.


The outcome of an email authentication check (RFC 8601 Authentication-Results) — a method (DKIM, SPF, DMARC, ARC), a verdict, and the verifying server.


A coordinate axis or dimension of a reference frame (e.g. X, Y, Z, latitude, longitude, elevation, time).


A parent-child relationship by biological descent.


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.


A block of transactions on a distributed ledger or blockchain.


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.


A blockchain network identified by a chain identifier (e.g. CAIP-2 chainId).


A MIME part of a message's body, with a media type and content.


A concrete published edition or release of a book — an out-of-universe information object and rights-bearing publication artifact. Distinct from the in-universe narrative frame it contributes to; linked via gmeow:sourceFor.


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.


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).


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).


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).


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.


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).


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.


The origin of a celestial coordinate system (topocentric, geocentric, barycentric, heliocentric, etc.). A value vocabulary aligned to IVOA refposition.


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.


A reference to a specific place within a source (a page, entry, image, or record locator).


A policy conflict-resolution strategy — the ODRL conflict values perm / prohibit / invalid.


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.


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.


The boolean operator of a logical constraint — odrl:and / odrl:or / odrl:xone (exactly one) / odrl:andSequence (ordered conjunction).


The comparison operator of an atomic constraint — the ODRL operator vocabulary (eq, neq, lt, lteq, gt, gteq, isPartOf, isA, isAnyOf, …).


A means of reaching an agent: an email address, telephone number, or postal address.


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.


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).


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).


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.


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.


A reified couple relationship (marriage, civil union, or partnership) between two persons; bears marriage, divorce and related events.


An information artifact resulting from creative or intellectual effort — a document, article, dataset, media object, or web page.


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.


An educational or occupational credential held by an agent — a degree, certification, or license.


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.


A cryptographic signature over a message or its headers, asserting origin and integrity.


A DomainKeys Identified Mail signature (RFC 6376) over selected headers and the body.


A collection of data published as a unit.


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.


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.


A bounded textual or digital document — a file, record, or report.


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.)


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).


A contact point reachable via the Simple Mail Transfer Protocol (SMTP).


An RFC 5322 email message, with headers, participants, a thread, body parts and mailbox residence.


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.


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.


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.

closeMatch=crm:E5_Event closeMatch=lode:Event closeMatch=schema:Event closeMatch=sem:Event relatedMatch=bbc:NewsEvent relatedMatch=ical:Vevent relatedMatch=prov:Activity relatedMatch=wd:Q1656682


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.


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).


A kinship group of persons related by descent, marriage, or adoption.


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.


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.


A parent-child relationship through fostering.


The structural type of a reference frame (e.g. geodetic, Cartesian, polar, grid, narrative).


The physical, virtual, or conceptual domain of a reference frame (e.g. terrestrial, indoor, celestial, virtual, measurement, currency, temporal, colourspace, linguistic).


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.


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.


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.


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.


A geographic point expressed as latitude, longitude, and optional elevation.


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.


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).


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.).


The grammatical aspect of an event mention in text — a VALUE vocabulary for ISO-TimeML interoperability (perfective / progressive / perfective-progressive / none).


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.


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.


A collection of agents treated as a unit without the formal structure of an organization.


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.


The domain of an honorific (academic, clerical, noble, military, judicial, social).


Whether an honorific is rendered before (prefix) or after (suffix) the name.


A reified, SELF-ASSERTED claim about an aspect of a person's identity — an observation in the universal claim stack (#69): 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.


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.


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.


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.


A reified standing relationship between agents (acquaintance, collaboration, …), able to bear its own time interval, confidence, and source evidence.


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).


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.


A reified kinship relationship between persons, modelled as an observation (a claim-from-a-vantage) in the universal stack (#69). 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.


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).


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).


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.


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).


The sensory/transmission channel of a language (spoken, signed, written, whistled, tactile, machine, multimodal). A value carried by gmeow:languageModality.


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.


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.


The vitality status of a language (living, historical, extinct, dormant, revived, emerging, proposed, constructed-active). A value carried by gmeow:languageStatus.


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.


An event emitted by a smart contract or recorded on a ledger — a log entry, oracle callback, or bridge message.


The finality state of a ledger transaction or block — a value vocabulary (individuals, never subclasses).


A transaction recorded on a distributed ledger or blockchain — the information-object representation of the payload, not the on-chain bytes themselves.


The dimension an atomic constraint tests — an OPEN value vocabulary mirroring the ODRL leftOperand vocabulary (dateTime, spatial, count, purpose, recipient, industry, …).


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.

closeMatch=cc:License closeMatch=dcterms:LicenseDocument closeMatch=odrl:Offer closeMatch=premis:License closeMatch=spdx:License closeMatch=spdx:ListedLicense closeMatch=wd:Q79719


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.


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.


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.


The state of a moving entity at a specific point or period in time, including its location, velocity, and pose (position + orientation).


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.


A named container of messages within an account — a folder, JMAP mailbox, or Gmail label.


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).


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).


An alias for gmeow:Quantity — the measured-value perspective on the same value×unit/frame×determinacy×provenance bundle (#77). Equivalent to gmeow:Quantity and gmeow:ScalarQuantity. Provided for consumers who prefer the 'measured value' terminology common in metrology and sensor standards.


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.


The reified relationship by which an agent is a member of an organization, optionally playing a role over a period of time.


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).


A communication sent from one agent to others — the parent of email and other message kinds.


A single RFC 5322 header field (name and value) of a message.


A flag/keyword applied to a message (IMAP flag or JMAP keyword) such as seen, flagged, answered, draft, forwarded, or junk.


A reified occurrence of an email address in a particular message header or envelope context.


The role an address occurrence plays in a message header or envelope.


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.


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.


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.


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.


The social register of a name-usage (formal, intimate, professional, casual). A value vocabulary carried by gmeow:usageRegister on a gmeow:NameUsage.


A reified, context-dependent use of an appellation — an observation in the universal claim stack (#69): 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.


A named stretch of time with defined bounds — a geologic era, historical dynasty, artistic period, fiscal year, or any other culturally salient temporal division.


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.


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.


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.


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.


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).


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.

closeMatch=crm:E13_Attribute_Assignment closeMatch=prov:Entity closeMatch=sosa:Observation skos:broadMatch=sosa:Sampling


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).


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.


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.


A kind of work or profession, such as those classified by ESCO or SOC.


An account an agent holds with an online service — a social profile, code-forge account, or decentralized identity.


A structured group of agents — a company, institution, association, or governmental body — able to act as a single agent.


An appellation borne by an organization — a legal name, a trading / 'doing-business-as' name, or a former name.


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.


An OpenPGP signature (RFC 4880/9580, PGP-MIME RFC 3156) over a message, bound to a PGP key.


A reified parent-child relationship, typed by its nature (biological, adoptive, step, or foster).


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.


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.


A granted or filed patent describing an invention.


The kind of a named period (geologic eon, era, period, epoch, age; historical dynasty, era; fiscal year). A value, never a subclass.


A rule that grants the ability to exercise a gmeow:RightsAction over the governed asset (odrl:Permission). Its required duties ride gmeow:hasDuty.


An individual human being, living or deceased.

closeMatch=gxv:Person equivalentClass=foaf:Person equivalentClass=gedcom:Individual equivalentClass=schema:Person exactMatch=wd:Q5


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.


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.


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.


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.


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).


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.


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.


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.


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.


An interpersonal relationship arising from work — colleagues, collaborators, a client and a provider (the reified form of hasWorkedWith).


An attained proficiency level on a scale (CEFR A1–C2; native; heritage). A value carried by gmeow:proficiencyLevel; gmeow:levelScale ties it to its scale. ILR (0–5) and ACTFL levels are added as further individuals.


The skill channel a language proficiency rates (speaking, listening, reading, writing, signing, comprehension, overall). A value carried by gmeow:proficiencyModality.


A framework for rating language proficiency (CEFR, ILR, ACTFL, self-reported). A value carried by gmeow:proficiencyScale and gmeow:levelScale.


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.


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.


A rule that forbids the exercise of a gmeow:RightsAction over the governed asset (odrl:Prohibition).


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.


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.


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).


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).


A universal scalar numeric value bundled with unit/frame, determinacy, and provenance — the synthesis of FRAME-GEN + DET-GEN + OBS (#77). 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.


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.)


A reference system (such as a coordinate system, datum, grid, or platform space) relative to which locations, coordinates, or measurements are expressed.

closeMatch=fibo-fnd-acc-cur:Currency closeMatch=knowrob:FrameOfReference closeMatch=lvont:Language closeMatch=qudt:Unit closeMatch=time:TRS


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.


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).


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).


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.


A version-control repository holding the source code of a software project.


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.


A reified, machine-readable statement of the rights situation of an entity — an observation in the universal claim stack (#69). 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.


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.


A function or position an agent plays in some context, such as a job title or organizational role.


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).


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.


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.


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.


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).


An S/MIME signature (RFC 8551) over a message, bound to an X.509 certificate.


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.


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.


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).


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).


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).


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).


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).


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).


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.


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).


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 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.


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.


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.


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).


A competency or ability an agent possesses.


A deployed program on a blockchain or distributed ledger, identified by a contract address.


A software process or autonomous program that acts on behalf of a person or organization.


An appellation borne by a software project — a product name, project name, or package name. Carries its own gmeow:nameLanguage and gmeow:nameScript so co-equal multilingual names (e.g. localized product names) are separate first-class objects.


A software project: a body of source code developed and released as a unit, with repositories, releases, and contributors.


A source from which evidence is drawn: a record, certificate, register, archive entry, or publication.


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.


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.


A set of coordinate values representing a position in a specific coordinate reference frame.


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).


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.


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).

closeMatch=crminf:I5_Inference_Making closeMatch=iao:assertion closeMatch=oa:Annotation closeMatch=sosa:Observation


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): gmeow:unequivocal, gmeow:probable, gmeow:conceivable, gmeow:refuted. Absence of a value is read as unequivocal.


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.


A parent-child relationship through marriage to a biological/adoptive parent.


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.


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).


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.


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.


A condensed account derived from a source information object (often machine-generated), linked to its source by gmeow:wasDerivedFrom.


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.


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.


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.


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).


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.


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.


The writing direction of a writing system (ltr, rtl, vertical, boustrophedon, non-linear, contextual). A value carried by gmeow:textDirection.


The text content extracted from a source object (e.g. a PDF attachment), linked to its source by gmeow:wasDerivedFrom.


A conversation: a set of messages related by reply/reference chains.


A bounded stretch of time, optionally open-ended, delimited by a start and/or end instant.


The atomic progression of time — TAI, TT, UTC, GPS, UT1, TDB, etc. A time scale is independent of any calendar or geographic reference position.


A reified relationship that holds only over a particular time interval — the base for residence, tenure, and membership-over-time situations.


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.


The registration status of a trademark — a VALUE: unregistered (™), registered (®), pending, expired, or cancelled. Open vocabulary.


A continuous path of motion representing the space-time history of a moving entity.


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).


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).


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.


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.


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.


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).


The outcome status of a verification result — a value vocabulary (individuals, never subclasses).


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 (#69). 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.


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.


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.


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.


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.


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).


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.


The structural kind of a writing system (alphabet, abjad, abugida, syllabary, logographic, featural, ideographic, pictographic, non-linear, mixed). A value carried by gmeow:writingSystemType.


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.
