range: Determinacy
definition: Relates a value, entity, or claim to its ontic determinacy model — the explicit facet recording whether the value is crisp, vague, fuzzy, probabilistic, or disputed. Domain-free (universal, like hasGranularity). NOT functional: in a multi-source merge sources may state different determinacy models, and those claims coexist rather than force the reasoner to collapse distinct models. Distinct from gmeow:confidence (epistemic certainty) and from gmeow:determinacyModel (the frame-level default for a ReferenceFrame).

wasTerminatedIn
type: ObjectProperty
domain: Endurant
range: Event
comment: Identifies the gufo:Event in which the gufo:Endurant was brought to an end. For example, the Space Shuttle Challenger (OV-099) (a gufo:FunctionalComplex) was destroyed during the launch of its tenth flight (a gufo:Event). Benevides et al. (2019) only discussed termination of objects; gufo:wasCreatedIn is extended to endurants in general. This means that a gufo:Relator (such as a marriage) can be declared terminated. Further, in that work "terminatedBy" required the event to be "triggered" by a situation in which the terminated object is present. We relax this requirement here, such that the object may be created and terminated in the scope of the identified gufo:Event. A. B. Benevides, J. R. Bourguet, G. Guizzardi, R. Penãloza, and J. P. A.

range: Granularity Level
definition: Relates a value, place, period, coordinate or measurement to its own resolution level — the explicit 'no silent precision' facet, queryable independently of any disclosure control.

has perceived condition
type: ObjectProperty

definition: The shape descriptor of a CoordinateMatrix (e.g. '4×1' for a colourspace tuple, '256×1' for a spectral vector, '640×480×3' for a thermal image). Enables the solver layer to parse matrixValue correctly without inferring shape from the literal content (Principle 12).

coordinate matrix frame
type: ObjectProperty
type: FunctionalProperty
sub property of: has reference frame
domain: Coordinate Matrix
range: Reference Frame
definition: The reference frame in which this CoordinateMatrix is expressed. Functional: a matrix is expressed in exactly one frame; frame transformation is a solver concern (Principle 12). Sub-property of gmeow:hasReferenceFrame so the frame-inheritance property chain (isResultOf ∘ hasReferenceFrame ⊑ hasReferenceFrame) applies automatically.

partitions
type: ObjectProperty
sub property of: categorizes
domain: Class
  intersection of: Type
  intersection of: Class
    complement of: AbstractIndividualType
  intersection of: Class
    complement of: ConcreteIndividualType
comment: Identifies a gufo:Type whose instances are classified by exactly one instance of the partitioning higher-order type. For example, "AnimalSpecies" gufo:partitions "Animal". Instances of "AnimalSpecies" such as "Lion", "Hiena" must be disjoint subclasses of "Animal". OWL 2 punning should be used to capture the two facets of "Lion" and "Hiena" in this example: (i) as instances of "AnimalSpecies", and (ii) as subclasses of "Animal". Note that the partitioned type (in the example "Animal") may or may not be declared to be a disjoint union of the explicitly enumerated subclasses (such as "Lion", "Hiena"). This is because other instances of the higher-order type ("AnimalSpecies") may exist that are not explicitly enumerated in the ontology. The partitioned type is termed the "base type" in the "powertype pattern" see Carvalho et al (2017), the higher-order type is often called the "powertype". For further details and formalization of "partitioning", see Carvalho et al (2017) which combines UFO with MLT (a multi-level modeling theory). V. A. Carvalho, J. P. A. Almeida, C. M. Fonseca, and G. Guizzardi, “Multi-level ontology-based conceptual modeling,” Data & Knowledge Engineering, vol. 109, p. 3–24, 2017. <http://dx.doi.org/10.1016/j.datak.2017.03.002>

    complement of: AbstractIndividualType
  intersection of: Class
    complement of: ConcreteIndividualType
range: Type
comment: Identifies a gufo:Type whose instances may be classified by instances of the categorizing higher-order type. For example, "ShipType" gufo:categorizes "Ship". Instances of "ShipType" such as "Supercarrier" and "Cargoship" should be declared subclasses of "Ship". OWL 2 punning should be used to capture the two facets of "Supercarrier" and "Cargoship" in this example: (i) as instances of "ShipType", and (ii) as subclasses of "Ship". The categorized type is termed the "base type" in the "powertype pattern" see Carvalho et al (2017), the higher-order type is often called the "powertype". gufo:categorizes is the general (unspecific) form of categorization. See gufo:partitions for a more specific form, in which instances of the categorized type are classified by exactly one instance of the higher-order type. The domain is gufo:Type excluding gufo:AbstractIndividualType as well as gufo:ConcreteIndividualTypes because those types are first-order types (their instances are individuals). Only instances of gufo:Type representing higher-order types can categorize a base type. For further details and formalization of "categorization", see Carvalho et al (2017) which combines UFO with MLT (a multi-level modeling theory). V. A. Carvalho, J. P. A. Almeida, C. M. Fonseca, and G. Guizzardi, “Multi-level ontology-based conceptual modeling,” Data & Knowledge Engineering, vol. 109, p. 3–24, 2017. <http://dx.doi.org/10.1016/j.datak.2017.03.002>

isProperPartOf
type: ObjectProperty
type: TransitiveProperty
domain: Thing
range: Thing
comment: Identifies a whole of which the entity is a proper part. gufo:isProperPartOf is the most generic parthood relation in this implementation. Use the various sub-properties provided in order to represent specific types of parthood. Proper parthood (and each of its sub-properties) is asymmetric and irreflexive. Nevertheless, these characteristics are not declared in this implementation since that would violate rules of OWL 2 DL that guarantee decidability of reasoning. Instead, we have focused only on declaring transitivity where applicable. Note that gufo:isProperPartOf (as the most general notion of parthood) is transitive, although the various sub-properties may not be transitive.

romanization
type: DatatypeProperty
domain: Appellation
range: Literal
definition: A Latin-script transliteration of THIS SAME appellation in another script (e.g. "Yamada Tarō" for "山田太郎"; pinyin for a Chinese name). Strictly a transliteration of one name — it NEVER bridges two distinct co-equal names (a Mandarin name is not the romanization of a Latin one).
scope note: Name the system that produced the romanization with gmeow:transliterationScheme (languages module) — Hepburn vs Kunrei for Japanese, Pinyin vs Wade-Giles for Mandarin — so the romanization records HOW it was derived; each scheme is catalogued as an FnO function in the projection layer.

Language is ALWAYS a first-class gmeow:Language (registry-INDEPENDENT, self-minted IRI) — never a bare BCP-47 literal; codes (e.g. "ja", "zh") live on the Language via gmeow:languageCode, so a code-less conlang or AI-minted language names co-equally. FUNCTIONAL — exactly one language per appellation: co-equal multilingual names are modelled as SEPARATE co-equal gmeow:Appellation instances (one per language), never by multi-tagging a single name (that is what keeps naming anti-colonial and symmetric). Drives locale-relative, symmetric display selection — never a ranking of one name above another. The script the form is written in is gmeow:nameScript (bridging to a first-class gmeow:WritingSystem).

version fingerprint
type: DatatypeProperty
domain: Entity
range: Literal
definition: A content fingerprint of the versioned entity — a hash, SWHID, content digest, or semantic identifier. Broader than gmeow:contentDigest (which is byte-exact and domain gmeow:Source): versionFingerprint covers semantic fingerprints where exact bytes are not the identity criterion (e.g. a normalized form, a canonicalized serialization). Non-functional: a single entity may carry several fingerprints under different algorithms or schemes.

Optional; ABSENT is read as unequivocal. Orthogonal to gmeow:confidence (our certainty about the standpoint's stance) and gmeow:accordingTo (whose frame). Refutation is what lets GMEOW distinguish a standpoint's explicit denial from its silence — the neutral-stance ambiguity flat models cannot resolve.

displayable
type: DatatypeProperty
range: boolean
definition: Whether a name or identity facet may be shown in interfaces and reports. The ONLY display control in the model — across naming (gmeow:Appellation) and identity (gmeow:IdentityFacet: gender/orientation), deliberately no preferred/primary marker (display selection is locale-relative and symmetric). It is intentionally domain-free so it applies to both. Superseded names (especially deadnames) and superseded gender/orientation labels set this false; consumers MUST honour false and never surface the string. NOT functional: in a multi-source merge, sources may disagree, and those claims must coexist rather than force a global inconsistency — the cautious value (false) wins at the projection layer. Cardinality is enforced by SHACL on data, not by the logical core.

usage namer
type: ObjectProperty
sub property of: vantage
domain: Name Usage
range: Agent
definition: An agent who uses the appellation for the named entity — the speaker/perspective holder. Non-functional: a usage may be shared by an audience of agents.

vantage
type: ObjectProperty
domain: Observation
range: Entity
definition: The agent or standpoint from which the observation is made — the reified-object-property counterpart of gmeow:accordingTo. Semantically, gmeow:vantage ⊑ gmeow:accordingTo: when an annotated statement is promoted to a reified Observation, its gmeow:accordingTo becomes the gmeow:vantage of the relator. The agent in the vantage role — an observer, a sensor, a perceiver — IS a standpoint (Principle 9): no frame is privileged, and every vantage is a co-equal facet from which the claim is held. Range is gmeow:Entity (encompassing both gmeow:Agent and gmeow:Standpoint) because a vantage may be a bare agent (person, organization, software agent, sensor) or a gmeow:Standpoint individual when the frame needs its own identity. Non-functional: joint observations (a reading co-authored by two agencies) are valid.
scope note: gmeow:vantage ⊑ gmeow:accordingTo: the reified relator edge is semantically subsumed by the annotation-property axis. This is NOT asserted as rdfs:subPropertyOf because gmeow:accordingTo is an owl:AnnotationProperty (keeping the OWL 2 DL downcast clean, Principle 3) while vantage is an owl:ObjectProperty. The subsumption is documented here and realised in the projection layer, not axiomatised in the reasoned core.

definition: The language a language-proficiency concerns. Functional — constitutive.

has stream
type: ObjectProperty
inverse of: stream of

type: ObjectProperty
type: FunctionalProperty
domain: Creative Work
range: Creative Work
definition: Relates a concrete edition, issue, or manifestation of a creative work to the stable work it editions. Functional per edition, non-merge semantics: editions remain first-class works with their own identifiers, dates, rights, and provenance.

has coordinates
type: ObjectProperty
domain: Place
range: Geo Coordinates
property chain axiom: has coordinate observation
property chain axiom: coordinate result
definition: Relates a place to its geographic point coordinates. Flat shortcut for the common case; the full relator form is a CoordinateObservation linking the place to a GeoCoordinates result via gmeow:coordinateResult, carrying provenance, reference frame, confidence, and standpoint (Principle 3). Non-simple: derived via property chain from the reified observation path.

endorses
type: ObjectProperty
domain: Agent
range: Agent
definition: A convenience shortcut recording that one agent vouches for another. Deliberately NOT symmetric (endorsement is directional) and NOT transitive (trust must not propagate inside the reasoner — that is the metric the perspectival TrustAssertion bounds). Use gmeow:TrustAssertion for leveled, dated, perspectival trust.

isEventProperPartOf
type: ObjectProperty
type: TransitiveProperty
sub property of: isProperPartOf
domain: Event
range: Event
comment: Identifies a gufo:Event of which the event is part. For example, Cristiano Ronaldo's penalty kick is an event proper part of the 2016 FIFA Club World Cup Final, having ocurred in the 60th minute of that match. That match is itself an event proper part of the 2016 FIFA Club World Cup. The match can be decomposed in different ways. For example, we can identify the participation of each player in the match (instances of gufo:Participation that are proper parts of the match) or decomposed the match using some temporal segmentation (each minute of the match, each of which is a proper part of the match). gufo:isEventProperPartOf is transitive.

membership interval
type: ObjectProperty
domain: Version Membership
range: Time Interval
definition: The time interval over which this version membership / role claim holds. A relator carries its period this way (matching gmeow:usageInterval, gmeow:taggingInterval, gmeow:relationshipInterval) rather than via gmeow:duringInterval, which is reserved for gufo:Situation-based time-scoped relations.

has destruction event
type: ObjectProperty
domain: Entity
range: Event
definition: Links an entity to the event that ended its existence — the general form of death (person), dissolution (organization), destruction (place), or retirement (frame, software). Non-functional: competing standpoint-indexed destruction claims coexist. A Person's death event is ALSO typed gmeow:eventTypeDeath. Suppression (gmeow:displayable false) is a display contract; destruction is an ontic fact — the entity is retained, merely marked as no longer extant.

inverse of: supersedes
domain: Entity
range: Entity

Directional, NOT symmetric. The superseded entity is retained (never deleted) and may carry gmeow:displayable false.

place supersedes
type: ObjectProperty
sub property of: supersedes

definition: The structural kind of a geometry (a gmeow:GeometryType individual). Non-functional: competing source classifications may differ (e.g. polygon vs multipolygon) and must coexist as evidence.

description
type: DatatypeProperty
domain: Entity
range: Literal
definition: A free-text note or description about an entity — the unstructured NOTE field (a biography, a remark, an annotation). Genuinely flat: unlike names, dates or roles, a note has no structure to reify. Distinct from skos:definition, which documents ontology TERMS rather than instances. Language-tag the literal where applicable; non-functional.

constitutes
type: ObjectProperty
domain: ConcreteIndividual

comment: Identifies a gufo:ConcreteIndividual that is constituted (partially) by the constituent individual. For example, the gufo:Collection of persons whose members are John, Paul, George, Ringo constituted the beatles, the gufo:Quantity of marble that constitutes the statue of Venus de Milo, and the gufo:Event of Paul raising his arm in a meeting that constitutes his voting (also a gufo:Event). In case constitution changes in time, see gufo:standsInQualifiedConstitution.

standsInQualifiedConstitution
type: ObjectProperty
sub property of: standsIn
domain: Endurant
range: TemporaryConstitutionSituation
comment: Identifies a gufo:TemporaryConstitutionSituation in which an endurant stands temporarily (as a constituent). The identified gufo:TemporaryConstitutionSituation is further related with an endurant (the whole) through the gufo:concernsConstitutedEndurant object property. This forms a pattern to represent temporary constitution, in which the relationships between constituents and constituted endurant vary in different situations. Consider, for example, a group of people (understood as a gufo:FixedCollection) constituting a band (understood as a gufo:FunctionalComplex). In this case, any change in the membership of the group (e.g., the replacement of one person) creates a different group of people. Therefore, the band's constitution can change in time, and the pattern using gufo:TemporaryConstitutionSituation is applicable.

definition: Disclosure control: marks a value/relator so that at projection time it is generalized to no finer than the named gmeow:GranularityLevel — a coarser ancestor is emitted instead of the precise value (e.g. an enclosing city rather than exact coordinates), never by deletion. The generalization sibling of gmeow:displayable false (withhold); together they are the single 'withhold or coarsen under a trigger' mechanism of CONSTITUTION P10. Domain-free, like gmeow:displayable. The coarse value is obtained by walking gmeow:generalizesVia (default gmeow:partOf); any geometry/geomask computation stays in the solver layer (P12). When both apply, displayable false (withhold) wins over coarsen.

historicallyDependsOn
type: ObjectProperty
type: TransitiveProperty
domain: ConcreteIndividual
range: ConcreteIndividual
comment: Identifies a gufo:ConcreteIndividual on which the concrete individual depends historically. For example, a person is historically dependent on his/her ancestors. When used between events, historical dependence encompasses causation (when the event is caused by the other), but also other cases where there is dependence but not causation (when the event brings about a situation that is either insufficient or more than sufficient to trigger the historically dependent event). For example, Real Madrid's goal in the 60th minute of the 2016 FIFA Club World Cup Final is historically dependent on (and in this case caused by) a penalty kick by Cristiano Ronaldo. The penalty kick itself is historically dependent on (but not caused by) a penalty (the occurrence of the penalty is necessary but not sufficient to cause the penalty kick as authorization of the referee is required). Historical dependence is transitive. Hence, in the example above, Real Madrid's goal is historically dependent on the penalty.

broughtAbout
type: ObjectProperty
domain: Event
range: Situation
comment: Identifies a gufo:Situation that is brought about by the gufo:Event. Guizzardi et al. (2013) included a notion of "brings-about" that related events to a single ("maximal") situation, embodying all the effects of the event at the time it ends. This implementation of gufo:broughtAbout diverges from "brings-about" in that work because gufo:broughtAbout can be used to relate events to more than one gufo:Situation. Each gufo:Situation identified through gufo:broughtAbout should be understood as an (improper) part of the maximal situation.

  on class: Object
comment: A gufo:Event that depends on a single object. Participations can be used to partition an event into portions, each of which depend exclusively on a single object. Consider a business meeting with multiple participants, including John and Mary. John's participation in the meeting encompasses all events that are part of the meeting and that depend solely on him. Likewise, Mary's participation encompasses all events that are part of the meeting and that depend solely on her. Similarly, in Brutus’ stabbing of Caesar, we may identify the participations of Brutus, of Caesar, and of the dagger.

contributedToTrigger
type: ObjectProperty
domain: Situation
range: Event
comment: Identifies a gufo:Event that the gufo:Situation contributed to trigger. Guizzardi et al. (2013) defined a notion of "triggers" to relate the situation satisfying all the sufficient and necessary conditions with the triggered event. This implementation differs from "triggers" as defined in that work because gufo:contributedToTrigger can be used to relate more than one gufo:Situation to a gufo:Event. Each gufo:Situation identified through gufo:contributedToTrigger should be understood as an (improper) part of the situation that triggered the event.

according to
type: AnnotationProperty
definition: The standpoint / frame within which the annotated statement is asserted true — *according to whom*. DISTINCT from gmeow:wasAttributedTo (which source RECORDED the claim) and gmeow:confidence (how sure we are); a claim may carry all three with no inferential bridge among them. Its value is a gmeow:Agent (a polity, community, or organization IRI) or a gmeow:Standpoint individual (a frame that needs its own identity). When a statement is promoted to a reified gmeow:Observation, gmeow:accordingTo becomes the gmeow:vantage of the relator (vantage ⊑ accordingTo — documented, not axiomatised, because accordingTo is an AnnotationProperty and vantage is an ObjectProperty). Standpoint-TIME — when the frame held this position — rides gmeow:validFrom / gmeow:validUntil on the same statement in the light case, or a reified gmeow:StandpointTenure when the adoption / withdrawal is itself the fact of interest. The range is intentionally open. An unindexed statement is held according to gmeow:universalStandpoint (the uncontested global facts).

wasCreatedIn
type: ObjectProperty
domain: Endurant
range: Event
comment: Identifies the gufo:Event which brought the gufo:Endurant into existence. For example, a musical piece is created in an act of composition (or in an event that is part of it), a piece of legislation is created in a complex legislative process. Benevides et al. (2019) only discussed creation of objects; gufo:wasCreatedIn is extended to endurants in general. Further, in that work "createdBy" required the event to "bring about" a situation in which the created object is present. We relax this requirement here, such that the object may be created and terminated in the scope of the identified gufo:Event. A. B. Benevides, J. R. Bourguet, G. Guizzardi, R. Penãloza, and J. P. A. Almeida, “Representing a reference foundational ontology of events in SROIQ,” Applied ontology, vol. 14, iss. 3, p. 293–334, 2019. <http://dx.doi.org/10.3233/AO-190214>

definition: 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.

overlay place
type: ObjectProperty
type: FunctionalProperty
domain: Regulatory Overlay
range: Place
definition: The place over which this regulatory overlay applies. Functional: an overlay concerns exactly one place (constitutive of the situation's identity). The place carries the geographic geometry; the overlay carries the regulation and temporal scope.

Name Purpose
type: Class
type: NamedIndividual
type: AbstractIndividualType
subclass of: QualityValue
definition: 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.

subclass of: Information Object
definition: A reified component of a structured appellation — a given name, a surname, a patronymic, a nobiliary particle, an Arabic nisba, a filename extension.

isObjectProperPartOf
type: ObjectProperty
type: TransitiveProperty
sub property of: isProperPartOf
domain: Object
range: Object
comment: Identifies a gufo:Object of which the object is a part. This is a general parthood relation between objects. Use the various sub-properties provided in order to represent specific types of parthood, each of which has specialized semantics (and different formal properties in this implementation, in particular, transitivity (Guizzardi, 2005, section 5.6).

Temporal Measurement
type: Class
type: NamedIndividual
type: SubKind
subclass of: Relator
subclass of: Measurement
subclass of: Restriction
  on property: observed feature
  some values from: Entity
subclass of: Restriction
  on property: vantage
  some values from: Agent
definition: 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.

type: NamedIndividual
type: SubKind
subclass of: Creative Work
definition: A bounded textual or digital document — a file, record, or report.

Standpoint Tenure
type: Class
type: NamedIndividual
type: SituationType
subclass of: Time-Scoped Relation
subclass of: Restriction
  on property: standpoint claim
  some values from: Standpoint Claim
subclass of: Restriction
  on property: tenure standpoint
  some values from: Standpoint
definition: 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.

Atomic Constraint
type: Class
type: NamedIndividual
type: Kind
subclass of: Constraint

type: AbstractIndividualType
subclass of: QualityValue
definition: 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).

Copyright Status
type: Class
type: NamedIndividual
type: AbstractIndividualType
subclass of: QualityValue
definition: 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.

version member
type: ObjectProperty
type: FunctionalProperty
sub property of: observed feature
domain: Version Membership
range: Entity
definition: The concrete entity that participates in a version set via this membership — a software release, a book edition, an email variant, a dataset snapshot. Functional per relator: one member per VersionMembership.

is result of
type: ObjectProperty
inverse of: observation result
domain: Entity
range: Observation
definition: Relates an entity (typically an observation result such as a quantity, coordinate set, or quality value) back to the Observation that produced it — the explicit provenance axis of the value×unit/frame×determinacy×provenance bundle (#77). Domain is gmeow:Entity (universal, matching the range of observationResult) so any result type can carry provenance. Non-functional: a result entity may be produced by multiple observations (e.g. a consensus value derived from several readings), and those claims coexist rather than collapse.

observation result
type: ObjectProperty
domain: Observation
range: Entity
definition: The entity-valued result of an observation — a coordinate set, an instant, a quality value, a quantity, or another entity. For literal scalar readings (e.g. 22.5°C), the observationResult entity carries the literal via a datatype property (e.g. qudt:quantityValue or a module-specific scalar property). Non-functional: a single observation may yield several results in different frames or granularities, and competing result claims coexist rather than collapse.

Copyright
type: Class
type: NamedIndividual
type: Kind
subclass of: Relator
subclass of: Restriction
  on property: copyright holder
  some values from: Agent
subclass of: Restriction
  on property: copyright work
  some values from: Information Object
definition: 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.

RoleMixin
type: Class
subclass of: AntiRigidType
subclass of: NonSortal
comment: A gufo:EndurantType that is both non-sortal and anti-rigid. It is defined by relational instantiation conditions. Role mixins are relationally dependent types, capturing relational properties shared by instances of different kinds. For example, "Customer" may be considered a gufo:RoleMixin as a superclass of the roles "CorporateCustomer" (specializing the gufo:Kind "BusinessOrganization") and "PersonalCustomer" (specializing the gufo:Kind "Person").

Repository
type: Class
type: NamedIndividual
type: Kind
subclass of: Information Object
definition: A version-control repository holding the source code of a software project.

Granularity Level
type: Class
type: NamedIndividual
type: AbstractIndividualType
subclass of: QualityValue
definition: 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.

Conflict Strategy
type: Class
type: NamedIndividual
type: AbstractIndividualType
subclass of: QualityValue
definition: A policy conflict-resolution strategy — the ODRL conflict values perm / prohibit / invalid.

FixedCollection
type: Class
subclass of: Collection
disjoint with: VariableCollection
comment: A gufo:Collection for which no change in membership is possible. Such a collection obeys an extensional principle of identity, i.e., two fixed collections are the same if, and only if, they have the same members. Consider, for example, a group of people understood as a gufo:FixedCollection. In this case, any change in the membership of the group (e.g., the addition of one person) would in fact create a different group of people. In this case, the gufo:FixedCollection may be contrasted with the complexes they constitute. For instance, The Beatles (the band conceived as a gufo:FunctionalComplex) was in a certain circumstance constituted by the collection {John, Paul, George, Pete} and in another one constituted by the collection {John, Paul, George, Ringo}. The replacement of Pete Best by Ringo Star does not alter the identity of the band, but creates a different group of people.

isCollectionMemberOf
type: ObjectProperty
sub property of: isObjectProperPartOf
domain: Object
range: Collection
comment: Identifies a gufo:Collection of which the object is a member. This is the relation between John and a group of persons, and between a cow and its herd. gufo:isCollectionMemberOf is intransitive (Guizzardi, 2005, p. 185). For membership in a gufo:VariableCollection, see gufo:standsInQualifiedParthood.

isSubCollectionOf
type: ObjectProperty
type: TransitiveProperty
sub property of: isObjectProperPartOf
domain: Collection
range: Collection
comment: Identifies a gufo:Collection of which the collection is a sub-collection. All members of the sub-collection are members of the identified super-collection. gufo:isSubCollectionOf is transitive (Guizzardi, 2005, p. 186). For parthood involving one or more varied collections, see gufo:standsInQualifiedParthood.

Standpoint
type: Class
type: NamedIndividual
type: Kind
subclass of: Entity
definition: 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.

Key Scheme
type: Class
type: NamedIndividual
type: AbstractIndividualType
subclass of: QualityValue
definition: 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.

contains place
type: ObjectProperty
domain: Place
range: Place
definition: The inverse of gmeow:containedInPlace — a place that geographically contains another place. Under OWL 2 semantics, transitivity is entailed because containedInPlace is transitive. GMEOW does not assert additional transitive property chains beyond the inverse declaration; transitive closure is a solver concern (Principle 12).

Skill
type: Class
type: NamedIndividual
type: Kind
subclass of: Entity
definition: A competency or ability an agent possesses.

issued at
type: DatatypeProperty
type: FunctionalProperty
domain: Attestation
range: dateTime
definition: The instant an attestation was issued. Functional: the issue time is constitutive of the attestation's identity.

assessed entity
type: ObjectProperty
sub property of: observed feature
domain: Quality Assessment
range: Entity
definition: The entity whose data quality is being assessed — the feature of interest of the quality observation. Sub-property of gmeow:observedFeature so generic consumers can query 'all observations about Alice' without knowing whether the claim is a name, a coordinate, or a quality assessment.

attested subject
type: ObjectProperty
inverse of: has attestation
domain: Attestation
range: Entity
definition: The entity that an attestation is about — the thing being vouched for. Non-functional: an attestation may concern multiple subjects (e.g. a key↔identity binding certifies both a key and an identity), and competing subject claims coexist (Principle 9).

has attestation
type: ObjectProperty
domain: Entity
range: Attestation
definition: Relates an entity to an attestation about it — the inverse of gmeow:attestedSubject. Non-functional: an entity may have many co-existing attestations from different attesters (Principle 9).

statement about
type: ObjectProperty
sub property of: observed feature
domain: Rights Statement
range: Entity
definition: The asset a rights statement governs — the ODRL target. Usually the inverse of gmeow:hasRightsStatement; asserted on the relator so the statement is self-contained.

TemporaryInstantiationSituation
type: Class
subclass of: Situation
subclass of: Restriction
  on property: concernsNonRigidType
  qualified cardinality: 1
  on class: NonRigidType
subclass of: Restriction
  on property:
    inverse of: standsInQualifiedInstantiation
  qualified cardinality: 1
  on class: Endurant
disjoint with: TemporaryParthoodSituation
disjoint with: TemporaryRelationshipSituation
comment: A gufo:Situation in which a gufo:Endurant temporarily instantiates a gufo:NonRigidType. A gufo:TemporaryInstantiationSituation can account for the time period in which a particular instantiation holds. Examples include: the situation in which Obama instantiates the role of president, which began in 20/01/2009 and lasted until 20/01/2017; the situation in which Coatria instantiates the role of EU Member, which began in 01/07/2013 (and is still on-going); and the situation in which Steve Jobs instantiates the child phase, which began in 24/02/1955 and lasted until 24/02/1965. This solution is inspired in the qualified relation pattern (http://patterns.dataincubator.org/book/qualified-relation.html).

Organization Name
type: Class
type: NamedIndividual
type: SubKind
subclass of: Appellation
definition: An appellation borne by an organization — a legal name, a trading / 'doing-business-as' name, or a former name.

Text Direction
type: Class
type: NamedIndividual
type: AbstractIndividualType
subclass of: QualityValue
definition: The writing direction of a writing system (ltr, rtl, vertical, boustrophedon, non-linear, contextual). A value carried by gmeow:textDirection.

Group
type: Class
type: NamedIndividual
type: Kind
subclass of: Collection
subclass of: Entity
definition: A collection of agents treated as a unit without the formal structure of an organization.

Observation
type: Class
type: NamedIndividual
type: Kind
subclass of: Relator
subclass of: Restriction
  on property: observed feature
  some values from: Thing
subclass of: Restriction
  on property: vantage
  some values from: Entity
definition: 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.

rcc8 po
type: ObjectProperty
type: SymmetricProperty
domain: Location
range: Location
definition: RCC-8: Partial Overlap (PO) — regions overlap but neither is part of the other.

Time Scale
type: Class
type: NamedIndividual
type: Kind
subclass of: Object
subclass of: Entity
definition: The atomic progression of time — TAI, TT, UTC, GPS, UT1, TDB, etc. A time scale is independent of any calendar or geographic reference position.

tagging tag
type: ObjectProperty
type: FunctionalProperty
domain: Tagging
range: Tag
definition: The tag applied in a tagging act. Functional per relator: one tag per Tagging.

hasBeginPoint
type: ObjectProperty
domain: ConcreteIndividual
range: Instant
comment: Identifies the begin point for a gufo:ConcreteIndividual, in the case in which time instants are reified. In the case of endurants, this identifies the time point when the endurant comes into existence. In the case of events, this identifies the time point when the event starts to take place. In the case of situation, this identifies the time point when the situation begins to hold. If time instants are not reified, use gufo:hasBeginPointInXSDDate or gufo:hasBeginPointInXSDDateTimeStamp.

hasBeginPointInXSDDate
type: DatatypeProperty
type: FunctionalProperty
domain: ConcreteIndividual
range: date
comment: Determines the begin point for a gufo:ConcreteIndividual, using a xsd:date literal. In the case of endurants, gufo:asBeginPointInXSDDate determines the time point when the endurant comes into existence. In the case of events, this data property determines the time point when the event starts to take place. In the case of situation, it determines the time point when the situation begins to hold. Use gufo:hasBeginPoint instead when temporal entities are reified.

hasBeginPointInXSDDateTimeStamp
type: DatatypeProperty
type: FunctionalProperty
domain: ConcreteIndividual
range: dateTimeStamp
comment: Determines the begin point for a gufo:ConcreteIndividual, using a xsd:dateTimeStamp literal. In the case of endurants, gufo:hasBeginPointInXSDDateTimeStamp determines the time point when the endurant comes into existence. In the case of events, this data property determines the time point when the event starts to take place. In the case of situation, it determines the time point when the situation begins to hold. Use gufo:hasBeginPoint instead when temporal entities are reified.

Accessibility Polarity
type: Class
type: NamedIndividual
type: AbstractIndividualType
subclass of: QualityValue
definition: The polarity of an accessibility assertion — feature (positive), barrier (negative), or limited (partial).

Geo Coordinates
type: Class
type: NamedIndividual
type: Kind
subclass of: Entity
definition: A geographic point expressed as latitude, longitude, and optional elevation.

Grammatical Tense
type: Class
type: NamedIndividual
type: AbstractIndividualType
subclass of: QualityValue
definition: 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.

Message Header
type: Class
type: NamedIndividual
type: Kind
subclass of: Information Object
definition: A single RFC 5322 header field (name and value) of a message.

contract address
type: DatatypeProperty
type: FunctionalProperty
domain: Smart Contract
range: Literal
definition: The address at which a smart contract is deployed.

Person Name
type: Class
type: NamedIndividual
type: SubKind
subclass of: Appellation
definition: 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.

Trademark
type: Class
type: NamedIndividual
type: Kind
subclass of: Relator
subclass of: Restriction
  on property: trademark holder
  some values from: Agent
subclass of: Restriction
  on property: trademark mark
  some values from: Mark
definition: 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.

Romantic Orientation Value
type: Class
type: NamedIndividual
type: AbstractIndividualType
subclass of: QualityValue
definition: 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.

Language
type: Class
type: NamedIndividual
type: Kind
subclass of: Information Object
definition: 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.

Attestation Artifact
type: Class
type: NamedIndividual
type: Kind
subclass of: Information Object
subclass of: Restriction
  on property: artifact media type
  some values from: Literal
definition: 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.

hasEndPointInXSDDateTimeStamp
type: DatatypeProperty
type: FunctionalProperty
domain: ConcreteIndividual
range: dateTimeStamp
comment: Determines the end point for a gufo:ConcreteIndividual using a xsd:dateTimeStamp literal. In the case of endurants, gufo:hasEndPointInXSDDateTimeStamp determines the time point when the endurant ceases to exist. In the case of events, this data property determines the time point when the event ends. In the case of situation, it determines the time point when the situation ceases to hold. Use gufo:hasEndPoint instead when temporal entities are reified.

hasEndPoint
type: ObjectProperty
domain: ConcreteIndividual
range: Instant
comment: Identifies the end point for a gufo:ConcreteIndividual, in the case in which time instants are reified. In the case of endurants, this identifies the time point when the endurant ceases to exist. In the case of events, this identifies the time point when the event ends. In the case of situation, this identifies the time point when the situation ceases to hold.

hasEndPointInXSDDate
type: DatatypeProperty
type: FunctionalProperty
domain: ConcreteIndividual
range: date
comment: Determines the end point for a gufo:ConcreteIndividual using a xsd:date literal. In the case of endurants, gufo:hasEndPointInXSDDate determines the time point when the endurant ceases to exist. In the case of events, this data property determines the time point when the event ends. In the case of situation, it determines the time point when the situation ceases to hold. Use gufo:hasEndPoint instead when temporal entities are reified.

Accessibility Assertion
type: Class
type: NamedIndividual
type: Kind
subclass of: Relator
subclass of: Restriction
  on property: assertion facet
  some values from: Accessibility Facet
subclass of: Restriction
  on property: assertion polarity
  some values from: Accessibility Polarity
subclass of: Restriction
  on property: assertion subject
  some values from: Entity
definition: 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.

sexual orientation value
type: ObjectProperty
type: FunctionalProperty
domain: Sexual Orientation
range: Sexual Orientation Value
definition: The gmeow:SexualOrientationValue a sexual-orientation facet asserts (functional per facet). A predefined individual or a fresh one with rdfs:label; the single path to the value.

ExtrinsicMode
type: Class
subclass of: ExtrinsicAspect
subclass of: Restriction
  on property: externallyDependsOn
  some values from: ConcreteIndividual
subclass of: Restriction
  on property: inheresIn
  qualified cardinality: 1
  on class: ConcreteIndividual
disjoint with: Relator
comment: A gufo:ExtrinsicAspect that inheres in a concrete individual and depends on others for its existence. A gufo:ExtrinsicMode can be understood as a reified one-sided relationship, such as John's admiration for Mary. Corresponds to "Extrinsic Moment" in Fonseca et al (2019). Encompasses what "Externally Dependent Mode", "Qua Individual" and "Relator" in Guizzardi (2005).

externallyDependsOn
type: ObjectProperty
type: IrreflexiveProperty
domain: ExtrinsicMode
range: Endurant
comment: Identifies a gufo:Endurant on which the gufo:ExtrinsicMode depends. For example, John's duty to return the book he borrowed from Mary (a gufo:ExtrinsicMode) depends externally on Mary. The identifed gufo:Endurant should be external to the bearer of the extrinsic mode (see Guizzardi, 2005, p. 239). In other words, the identified endurant should not be a part or an intrisic aspect of the bearer of the extrinsic mode.

inheresIn
type: ObjectProperty
type: FunctionalProperty
type: AsymmetricProperty
type: IrreflexiveProperty
domain: Aspect
range: ConcreteIndividual
comment: Identifies the gufo:ConcreteIndividual in which the gufo:Aspect inheres. Inherence is a sort of existential dependence. The identified concrete individual is the "bearer" of the aspect. For example, the color of an object inheres in the object and the average speed of a flight inheres in the flight.

Endurant
type: Class
subclass of: ConcreteIndividual
disjoint union of: Aspect
disjoint union of: Object
comment: A gufo:ConcreteIndividual that endures in time and may change qualitatively while keeping its identity. Examples include: ordinary objects of everyday experience, such as a person, a house, and a car; reified relationships, such as a marriage, a rental contract, and a person's love for another; and existentially-dependent aspects of objects, such as a car's weight, a person's language skills, and a house's color. Also termed "continuant" in the philosophical literature.

Measurement
type: Class
type: NamedIndividual
type: SubKind
subclass of: Observation
definition: 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.

Sensory Modality
type: Class
type: NamedIndividual
type: AbstractIndividualType
subclass of: QualityValue
definition: 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).

Identity Facet
type: Class
type: NamedIndividual
type: SubKind
subclass of: Relator
subclass of: Observation
subclass of: Restriction
  on property: facet subject
  some values from: Person
subclass of: Restriction
  on property: facet vantage
  some values from: Agent
definition: 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.

Entity Existence
type: Class
type: NamedIndividual
type: SituationType
subclass of: Time-Scoped Relation
subclass of: Restriction
  on property: existence entity
  some values from: Entity
definition: 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.

Place Name
type: Class
type: NamedIndividual
type: SubKind
subclass of: Appellation
definition: 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.

Participant Role
type: Class
type: NamedIndividual
type: AbstractIndividualType
subclass of: QualityValue
definition: 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.

concernsConstitutedEndurant
type: ObjectProperty
domain: TemporaryConstitutionSituation
range: Endurant
comment: Identifies the constituted gufo:Endurant in the gufo:TemporaryConstitutionSituation.

Event
type: Class
subclass of: ConcreteIndividual
comment: A gufo:ConcreteIndividual that 'occurs' or 'happens' in time. They may be instantaneous or long-running. Events are those "things that happen to or are performed by" (Casati and Varzi, 2015) endurants. Examples include actions and processes, such as a business meeting, a communicative act, a soccer match, a goal kick, the clicking of a mouse button; as well as natural occurrences such as an earthquake, the fall of the meteor that caused the extinction of the dinosaurs. Also termed "happening", "occurrence", "perdurant" or "occurrent" in the philosophical literature. Casati, R. & Varzi, A. (2015). Events. In E.N. Zalta (Ed.), The Stanford Encyclopedia of Philosophy (Winter 2015 ed.). 19 Metaphysics Research Lab, Stanford University. https://plato.stanford.edu/archives/win2015/entries/events/

Period Type
type: Class
type: NamedIndividual
type: AbstractIndividualType
subclass of: QualityValue
definition: The kind of a named period (geologic eon, era, period, epoch, age; historical dynasty, era; fiscal year). A value, never a subclass.

Celestial Object Type
type: Class
type: NamedIndividual
type: AbstractIndividualType
subclass of: QualityValue
definition: 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.

Storage Location
type: Class
type: NamedIndividual
type: SubKind
subclass of: Location
definition: 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.

membership authority
type: ObjectProperty
sub property of: vantage
domain: Version Membership
range: Agent
definition: The agent or standpoint that asserts this version membership and its role — a project maintainer, a package registry, a publisher, a curator, or a self-asserting individual. NON-FUNCTIONAL: competing authority claims coexist without privilege (Principle 9). When the claim is promoted from a flat statement annotation, gmeow:accordingTo becomes the membershipAuthority of the relator.

Agreement Name
type: Class
type: NamedIndividual
type: SubKind
subclass of: Appellation
definition: 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.

Holocene Epoch

Standpoint Claim
type: Class
type: NamedIndividual
type: SubKind
subclass of: Observation
definition: 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).

day level
type: NamedIndividual
type: Granularity Level

Cadastral Reference
type: Class
type: NamedIndividual
type: Kind
subclass of: Information Object
definition: 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.

existence entity
type: ObjectProperty
type: FunctionalProperty
domain: Entity Existence
range: Entity
definition: The entity whose existence is recorded by this EntityExistence. Functional: an EntityExistence concerns exactly one entity (constitutive of the situation's identity).

Gender Expression Style
type: Class
type: NamedIndividual
type: AbstractIndividualType
subclass of: QualityValue
definition: 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.

definition: 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.

Biological Sequence Location
type: Class
type: NamedIndividual
type: SubKind
subclass of: Location
definition: 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.

Name Register
type: Class
type: NamedIndividual
type: AbstractIndividualType
subclass of: QualityValue
definition: The social register of a name-usage (formal, intimate, professional, casual). A value vocabulary carried by gmeow:usageRegister on a gmeow:NameUsage.

Scalar Quantity
type: Class
type: NamedIndividual
type: Kind
subclass of: Object
subclass of: Entity
definition: 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.

Version Set
type: Class
type: NamedIndividual
type: Kind
subclass of: Information Object
definition: 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.

Spatial Measurement
type: Class
type: NamedIndividual
type: SubKind
subclass of: Measurement
subclass of: Restriction
  on property: observed feature
  some values from: Entity
subclass of: Restriction
  on property: vantage
  some values from: Agent
definition: 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).

Information Object
type: Class
type: NamedIndividual
type: Category
subclass of: Object
subclass of: Entity
disjoint with: Physical Object
definition: 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.

Orientation
type: Class
type: NamedIndividual
type: Kind
subclass of: Object
subclass of: Entity
definition: 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.

Temporal Frame
type: Class
type: NamedIndividual
type: SubKind
subclass of: Object
subclass of: Reference Frame
definition: 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).

type: ObjectProperty
type: SymmetricProperty
domain: Location
range: Location
definition: RCC-8: Equal (EQ) — regions are identical.

ExtrinsicAspect
type: Class
subclass of: Aspect
disjoint with: IntrinsicAspect
disjoint union of: ExtrinsicMode
disjoint union of: Relator
comment: A gufo:Aspect that depends on one or more concrete individuals. Extrinsic (or "relational") aspects are reified relationships, e.g., John and Mary's marriage, Mary's employment contract at Nasa, or parts of those relationships, e.g., John's obligations towards Mary in the scope of the marriage, Mary's reciprocal claims, Mary's obligations towards John, John's reciprocal claims. Extrinsic aspects can also be reified one-sided relationships, e.g., John's admiration for Obama (which depends on Obama but does not characterize him). Corresponds to "Extrinsic Moment" in Fonseca et al (2019). Encompasses "Externally Depedent Mode", "Qua Individual" and "Relator" in Guizzardi (2005).

Coordinate Observation
type: Class
type: NamedIndividual
type: SubKind
subclass of: Spatial Measurement
subclass of: Restriction
  on property: observed feature
  some values from: Place
subclass of: Restriction
  on property: vantage
  some values from: Agent
definition: 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).

Language Modality
type: Class
type: NamedIndividual
type: AbstractIndividualType
subclass of: QualityValue
definition: The sensory/transmission channel of a language (spoken, signed, written, whistled, tactile, machine, multimodal). A value carried by gmeow:languageModality.

Filename
type: Class
type: NamedIndividual
type: SubKind
subclass of: Appellation
definition: 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.

Quantity
type: Class
type: NamedIndividual
type: Kind
equivalent class: Scalar Quantity
subclass of: Object
subclass of: Entity
definition: 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.

Software Agent
type: Class
type: NamedIndividual
type: Kind
subclass of: Agent
definition: A software process or autonomous program that acts on behalf of a person or organization.

Appellation
type: Class
type: NamedIndividual
type: Kind
subclass of: LexicalEntry
subclass of: Information Object
definition: 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'.

relationship party
type: ObjectProperty
domain: Interpersonal Relationship
range: Agent
definition: An agent who is one of the parties to an interpersonal relationship. Non-functional: a relationship typically binds two parties (and is left open for group ties).

rcc8 tppi
type: ObjectProperty
sub property of: has part
domain: Location
range: Location
definition: RCC-8: Tangential Proper Part Inverse (TPPi) — inverse of TPP.

Network Address Type
type: Class
type: NamedIndividual
type: AbstractIndividualType
subclass of: QualityValue
definition: 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).

Regulatory Overlay Type
type: Class
type: NamedIndividual
type: AbstractIndividualType
subclass of: QualityValue
definition: 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).

TemporaryConstitutionSituation
type: Class
subclass of: Situation
subclass of: Restriction
  on property: concernsConstitutedEndurant
  qualified cardinality: 1
  on class: Object
subclass of: Restriction
  on property:
    inverse of: standsInQualifiedConstitution
  qualified cardinality: 1
  on class: Object
disjoint with: TemporaryInstantiationSituation
disjoint with: TemporaryRelationshipSituation
comment: A gufo:Situation in which a gufo:Endurant temporarly constitutes another gufo:Endurant. When constitution of an object may change in time, it may be qualified by the period in time in which the relation applies. Examples include: the situation in which the Beatles is constituted by the group composed of {John,Paul,Ringo,George}; and the situation in which the statue of Venus de Milo was constituted by its original quantity of marble (including its arms). This is a reification of constitution (in a solution that is similar to the qualified relation pattern http://patterns.dataincubator.org/book/qualified-relation.html)

Narrative Reference Frame
type: Class
type: NamedIndividual
type: SubKind
subclass of: Reference Frame
definition: 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.

rcc8 ntppi
type: ObjectProperty
sub property of: has part
domain: Location
range: Location
definition: RCC-8: Non-Tangential Proper Part Inverse (NTPPi) — inverse of NTPP.

Programming Language
type: Class
type: NamedIndividual

jurisdiction polity
type: ObjectProperty
type: FunctionalProperty
domain: Jurisdiction Tenure
range: Agent
definition: The governing polity (state, administrative body, or organization) that held jurisdiction over the place during this tenure. Functional: a single tenure has exactly one governing polity.

type: Class
type: NamedIndividual
type: Kind
subclass of: Information Object
subclass of: Restriction
  on property: block hash
  some values from: Literal
subclass of: Restriction

definition: A block of transactions on a distributed ledger or blockchain.

Connection
type: Class
type: NamedIndividual
type: Kind
subclass of: Relator
definition: 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.

Prohibition
type: Class
type: NamedIndividual
type: Kind
subclass of: Rule
definition: A rule that forbids the exercise of a gmeow:RightsAction over the governed asset (odrl:Prohibition).

Contact Point
type: Class

subclass of: Object
subclass of: Entity
definition: A means of reaching an agent: an email address, telephone number, or postal address.

Rule
type: Class
type: NamedIndividual
type: Category
subclass of: Relator
subclass of: Restriction
  on property: rule action
  some values from: Rights Action
definition: 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).

Rights Action
type: Class
type: NamedIndividual
type: AbstractIndividualType
subclass of: QualityValue
definition: 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.

Creative Work
type: Class
type: NamedIndividual
type: Kind
subclass of: Information Object
definition: An information artifact resulting from creative or intellectual effort — a document, article, dataset, media object, or web page.

measured date
type: ObjectProperty
type: FunctionalProperty
domain: Temporal Measurement
range: Instant
definition: The absolute date instant yielded by a temporal measurement. Semantically plays the observationResult role for TemporalMeasurement, but is NOT asserted as rdfs:subPropertyOf gmeow:observationResult because gmeow:Instant (gufo:AbstractIndividual) is not a subclass of gmeow:Entity (gufo:Endurant), the range of gmeow:observationResult. Projection-layer alignment to time:hasTime lives in the mapping DSL.

Rights Statement
type: Class
type: NamedIndividual
type: SubKind
subclass of: Relator
subclass of: Observation
subclass of: Restriction
  on property: statement about
  some values from: Entity
definition: 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.

Honorific
type: Class
type: NamedIndividual
type: AbstractIndividualType
subclass of: QualityValue
definition: 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.

tagging tagger
type: ObjectProperty
domain: Tagging

Sexual Orientation
type: Class
type: NamedIndividual
type: SubKind
subclass of: Identity Facet

  on property: sexual orientation value
  some values from: Sexual Orientation Value
definition: 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.

point / exact coordinate level
type: NamedIndividual
type: Granularity Level

ComparativeRelationshipType
type: Class
subclass of: RelationshipType
disjoint with: MaterialRelationshipType
comment: A gufo:RelationshipType derived from intrinsic aspects of the related entities. For example, "heavierThan", "olderThan". For a gufo:ComparativeRelationshipType it is recommended to identify the types of intrinsic aspects from which it is derived (see gufo:isDerivedFrom). For example "heavierThan" is derived from the "Weight" quality type. Note that, in the case of relationships that may change in different circumstances or times, the use of a qualified relation pattern enables indicating the period of time in which the relationship holds. See gufo:TemporaryRelationshipSituation. Corresponds to "comparative formal relation" in Guizzardi (2005) and "Comparative Relation" in Fonseca et al. (2019).

isDerivedFrom
type: ObjectProperty
domain: Class
  union of: ComparativeRelationshipType
  union of: MaterialRelationshipType
range: EndurantType
comment: Identifies a gufo:EndurantType from which the material or comparative relation can be derived. The identified gufo:EndurantType should be a subclass of gufo:Aspect, more specifically a subclass of gufo:ExtrinsicAspect in the case of a gufo:MaterialRelationshipType, and a subclass of gufo:IntrinsicAspect in the case of a gufo:ComparativeRelationshipType. For example, "marriedWith" can be derived from "Marriage", "heavierThan" can be derived from "Weight". See Fonseca et al. (2019).

Honorific Position
type: Class
type: NamedIndividual
type: AbstractIndividualType
subclass of: QualityValue
definition: Whether an honorific is rendered before (prefix) or after (suffix) the name.

environment at location
type: ObjectProperty
type: FunctionalProperty
domain: Sensory Environment
range: Location
definition: The location whose ambient conditions this SensoryEnvironment describes. Functional: a SensoryEnvironment concerns exactly one location (constitutive of its identity).

Constraint
type: Class
type: NamedIndividual
type: Category
subclass of: Relator
definition: 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.

Axis
type: Class
type: NamedIndividual
type: Kind
subclass of: Object
subclass of: Entity
definition: A coordinate axis or dimension of a reference frame (e.g. X, Y, Z, latitude, longitude, elevation, time).

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

Geometry
type: Class
type: NamedIndividual

subclass of: Object
subclass of: Entity
definition: 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).

License Family
type: Class
type: NamedIndividual
type: AbstractIndividualType
subclass of: QualityValue
definition: 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.

Observation Method
type: Class
type: NamedIndividual
type: AbstractIndividualType
subclass of: QualityValue
definition: 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).

Role
type: Class
subclass of: AntiRigidType
subclass of: Sortal
comment: A gufo:EndurantType that both sortal and anti-rigid. It is defined by relational instantiation conditions. Roles are relationally dependent types, capturing relational properties shared by instances of a given kind. For example, "Student" may be considered a gufo:Role as a subclass of the gufo:Kind "Person", instantiated by all persons enrolled in a school.

EndurantType
type: Class
subclass of: ConcreteIndividualType
disjoint with: EventType
disjoint with: SituationType
disjoint union of: NonRigidType
disjoint union of: RigidType
disjoint union of: NonSortal
disjoint union of: Sortal
comment: A gufo:Type whose instances are endurants. Instances of gufo:EndurantType are subclasses of gufo:Endurant. Examples include the object kind "Person", the phase "Child", the relator kind "Marriage". See Guizzardi et al. (2018) for details concerning the taxonomy of endurant types included here.

type: Class
type: NamedIndividual
type: Kind
subclass of: Entity
definition: 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.)

concernsRelationshipType
type: ObjectProperty

  on property: attested subject
  some values from: Entity
subclass of: Restriction
  on property: attester
  some values from: Agent
subclass of: Restriction
  on property: issued at
  some values from: dateTime
definition: 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).

Place Type
type: Class
type: NamedIndividual
type: AbstractIndividualType
subclass of: QualityValue
definition: 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.

assertion facet
type: ObjectProperty
type: FunctionalProperty
domain: Accessibility Assertion
range: Accessibility Facet
definition: The accessibility facet being asserted. Functional per relator: one facet per AccessibilityAssertion.

Land Tenure Type
type: Class
type: NamedIndividual
type: AbstractIndividualType
subclass of: QualityValue
definition: 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).

overlay authority
type: ObjectProperty
type: FunctionalProperty
domain: Regulatory Overlay
range: Agent
definition: The authority (government body, international organization, regulatory agency, or indigenous council) that imposed this regulatory overlay. Functional: a single overlay has exactly one imposing authority.

domain: QualityValueAttributionSituation
range: QualityValue
comment: concernsQualityValue
comment: Identifies the gufo:QualityValue (i.e., the reified quality value) associated with the endurant that stands in the gufo:QualityValueAttributionSituation.

concernsQualityValue
type: DatatypeProperty
domain: QualityValueAttributionSituation
comment: Determines a quality value associated with the gufo:ConcreteIndividual that stands in the gufo:QualityValueAttributionSituation. Use gufo:concernsReifiedQualityValue instead when quality values are refied. It is recommended that subproperties of gufo:concernsQualityValue are created, possibly identifying the datatype to be used. For example, "concernsTemperatureValue" could be defined as a sub-property of gufo:concernsQualityValue with range xsd:double.

Postal Address
type: Class
type: NamedIndividual
type: SubKind
subclass of: Contact Point
definition: 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.

Narrative Frame Relation
type: Class
type: NamedIndividual
type: AbstractIndividualType
subclass of: QualityValue
definition: 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.

Tag Scheme
type: Class
type: NamedIndividual
type: Kind
subclass of: Information Object
definition: 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.

Quality Dimension
type: Class
type: NamedIndividual
type: AbstractIndividualType
subclass of: QualityValue
definition: 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).

Constraint Logic
type: Class

Storage Medium
type: Class
type: NamedIndividual
type: AbstractIndividualType
subclass of: QualityValue
definition: 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).

has spatial measurement
type: ObjectProperty
inverse of: spatial measurement of
domain: Entity
range: Spatial Measurement
definition: Links an entity to a spatial measurement describing its coordinates, geometry, pose, or spatial extent. Flat form for the common case; promote to full reified SpatialMeasurement when vantage, confidence, temporal scope, or standpoint matter.

ConcreteIndividualType
type: Class
subclass of: Type
disjoint with: RelationshipType
comment: A gufo:Type whose instances are concrete individuals. Instances of gufo:ConcreteIndividualType are subclasses of gufo:ConcreteIndividual. Examples include the gufo:Kind "Person", the gufo:Category "Physical Object", the gufo:EventType "Business Meeting".

participation participant
type: ObjectProperty
domain: Participation
range: Entity
definition: The entity that took part in the event in this participation. Range is gmeow:Entity (not only Agent) to admit non-agent participants — a document signed, a place visited. Non-functional: a joint role may be borne by several participants.

  qualified cardinality: 1
  on class: Endurant
subclass of: Restriction
  on property:
    inverse of: standsInQualifiedParthood
  qualified cardinality: 1
  on class: Endurant
disjoint with: TemporaryRelationshipSituation
comment: A gufo:Situation in which a gufo:Endurant is temporarily a part of another gufo:Endurant. A gufo:TemporaryParthoodSituation should only be used for mutable parts. It may be qualified by the period in time in which the relation applies. Examples include: the situation in which the United Kingdom is a member of the European Union; the situation in which Messi is a a member of the Barcelona FC squad; the situation in which an engine is part of a car; and the situation in which a transplanted heart is part of a person. Note that, since every instance of gufo:Quantity or gufo:FixedCollection only has essential parts, the gufo:TemporaryParthoodSituation should not be used to represent these parthood relations. This solution is inspired in the qualified relation pattern (http://patterns.dataincubator.org/book/qualified-relation.html).

Mailbox

standsInQualifiedParthood
type: ObjectProperty
sub property of: standsIn
domain: Endurant
range: TemporaryParthoodSituation
comment: Identifies a gufo:TemporaryParthoodSituation in which the endurant stands (as a temporary part). The identified gufo:TemporaryParthoodSituation is further related with an endurant (the whole) through the gufo:concernsTemporaryWhole object property. This forms a pattern to represent temporary parthood, in which the relationships between parts and wholes vary in different situations. In particular, this pattern is useful in case parts may be separated from their wholes, attached to other wholes, replaced.

standsIn
type: ObjectProperty
domain: Thing
range: Situation
comment: Identifies a gufo:Situation in which the entity stands. This implementation includes sub-properties of gufo:standsIn to identify situations concerning the attribution of (mutable) values to qualities, variable relationships, the instantiation of non-contingent types, temporary parthood and temporary constitution.

version set
type: ObjectProperty
type: FunctionalProperty
domain: Version Membership
range: Version Set
definition: The version set / lineage to which this membership belongs. Functional per relator: one set per VersionMembership.

Spatial Aggregation
type: Class
type: NamedIndividual
type: SubKind
subclass of: Measurement
definition: 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.

Celestial Reference Origin
type: Class
type: NamedIndividual
type: AbstractIndividualType
subclass of: QualityValue
definition: The origin of a celestial coordinate system (topocentric, geocentric, barycentric, heliocentric, etc.). A value vocabulary aligned to IVOA refposition.

Language Status
type: Class
type: NamedIndividual
type: AbstractIndividualType
subclass of: QualityValue
definition: The vitality status of a language (living, historical, extinct, dormant, revived, emerging, proposed, constructed-active). A value carried by gmeow:languageStatus.

Attachment
type: Class
type: NamedIndividual
type: SubKind
subclass of: Body Part
definition: 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.

coordinate result
type: ObjectProperty
sub property of: observation result
domain: Coordinate Observation
range: Geo Coordinates
definition: The GeoCoordinates result of a coordinate observation — a point expressed as latitude, longitude, and optional elevation. The reference frame in which the coordinates are expressed is carried on the observation via gmeow:hasReferenceFrame and propagates to the result via the existing isResultOf ∘ hasReferenceFrame chain.

Message
type: Class
type: NamedIndividual
type: Kind
subclass of: Information Object
definition: A communication sent from one agent to others — the parent of email and other message kinds.

Metric Kind
type: Class
type: NamedIndividual
type: AbstractIndividualType
subclass of: QualityValue
definition: 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.

log index
type: DatatypeProperty
type: FunctionalProperty
domain: Ledger Event
range: integer
definition: The index of a ledger event within its containing block or transaction.

Jurisdiction Tenure
type: Class
type: NamedIndividual
type: SituationType
subclass of: Time-Scoped Relation
subclass of: Restriction
  on property: jurisdiction place
  some values from: Place
subclass of: Restriction
  on property: jurisdiction polity
  some values from: Agent
definition: 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).

assertion subject
type: ObjectProperty
type: FunctionalProperty
domain: Accessibility Assertion
range: Entity
definition: The location or connection being assessed. Functional per relator: one subject per AccessibilityAssertion.

usage appellation
type: ObjectProperty
type: FunctionalProperty

domain: Name Usage
range: Appellation
definition: The appellation used to call the named entity in a name-usage.

Kind
type: Class
subclass of: RigidType
subclass of: Sortal
disjoint with: SubKind
comment: A gufo:EndurantType that is both sortal and rigid. It provides a uniform principle of identity for its instances. Every gufo:Endurant instantiates one and only one gufo:Kind. Examples include kinds of ordinary objects of everyday experience, such as: "Person", "House", "Car"; kinds of relators, such as "Marriage", "RentalContract"; kinds of existentially-dependent aspects of objects, such as "Weight", "Belief", "Vulnerability".

Containment Tenure
type: Class
type: NamedIndividual
type: SituationType
subclass of: Time-Scoped Relation
subclass of: Restriction
  on property: containment child
  some values from: Place
subclass of: Restriction
  on property: containment parent
  some values from: Place
definition: 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.

participation event
type: ObjectProperty
type: FunctionalProperty
domain: Participation
range: Event
definition: The event a participation is part of (functional — one event per participation).

Dating Method
type: Class
type: NamedIndividual
type: AbstractIndividualType
subclass of: QualityValue
subclass of: Observation Method
definition: 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.

Temporal Precision
type: Class
type: NamedIndividual
type: AbstractIndividualType
subclass of: QualityValue
definition: 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.

Relator
type: Class
subclass of: ExtrinsicAspect
subclass of: Restriction
  on property: mediates
  min qualified cardinality: 2
  on class: Endurant
comment: A gufo:ExtrinsicAspect that connects (involves, mediates) two or more concrete individuals. Relators are reified relationships composed of reciprocal extrinsic modes. Examples of relators include John and Mary's marriage (composed of John's obligations towards Mary in the scope of the marriage, Mary's reciprocal claims, Mary's obligations towards John, John's reciprocal claims), Mary's employment contract at Nasa, a covalent bond between two atoms.

mediates
type: ObjectProperty
type: AsymmetricProperty
type: IrreflexiveProperty
domain: Relator
range: Endurant
comment: Identifies the endurants mediated by a gufo:Relator. For example, John and Mary's marriage mediates John and Mary.

Version Scale
type: Class
type: NamedIndividual
type: AbstractIndividualType
subclass of: QualityValue
definition: 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.

License
type: Class
type: NamedIndividual
type: SubKind
subclass of: Agreement
subclass of: Restriction
  on property: licensed work
  some values from: Information Object
subclass of: Restriction
  on property: licensor
  some values from: Agent
definition: 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.

sub-organization of
type: ObjectProperty
type: TransitiveProperty
sub property of: part of
domain: Organization
range: Organization
definition: Relates an organization to a larger organization it is part of — a department or division within a company, a team within a department. Transitive (a team is part of the company through its division). A specialization of the universal gmeow:partOf spine. A department is thus a first-class gmeow:Organization, and a gmeow:Membership may target it directly. The 'department' field is the sub-organization a person's membership is in.

Cryptographic Key
type: Class
type: NamedIndividual
type: Kind
subclass of: Information Object
definition: 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.

Smart Contract
type: Class
type: NamedIndividual
type: Kind
subclass of: Entity
subclass of: Restriction
  on property: contract address
  some values from: Literal
definition: A deployed program on a blockchain or distributed ledger, identified by a contract address.

Body Part
type: Class
type: NamedIndividual
type: Kind
subclass of: Information Object
definition: A MIME part of a message's body, with a media type and content.

Left Operand
type: Class
type: NamedIndividual
type: AbstractIndividualType
subclass of: QualityValue
definition: The dimension an atomic constraint tests — an OPEN value vocabulary mirroring the ODRL leftOperand vocabulary (dateTime, spatial, count, purpose, recipient, industry, …).

year level
type: NamedIndividual
type: Granularity Level
coarser than: month level

Source
type: Class
type: NamedIndividual
type: Kind
subclass of: Information Object
definition: A source from which evidence is drawn: a record, certificate, register, archive entry, or publication.

concernsNonRigidType
type: ObjectProperty
type: FunctionalProperty
domain: TemporaryInstantiationSituation
range: NonRigidType
comment: Identifies the gufo:NonRigidType that is instantiated by the endurant that stands in a gufo:TemporaryInstantiationSituation.

tenure standpoint
type: ObjectProperty
type: FunctionalProperty
domain: Standpoint Tenure
range: Standpoint
definition: The standpoint whose position a standpoint-tenure records. When a StandpointTenure generates a StandpointClaim observation, the tenureStandpoint becomes the vantage of the claim.

tenure party
type: ObjectProperty
type: FunctionalProperty
domain: Land Tenure
range: Agent
definition: The party (person, corporation, indigenous community, or other agent) that holds the rights recorded by this LandTenure. Functional: a single tenure has exactly one party. Joint ownership is modelled as multiple co-equal LandTenure instances, none privileged (Principle 9).

Coordinate Matrix
type: Class
type: NamedIndividual
type: Kind
subclass of: Object
subclass of: Entity
definition: 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).

Named Period
type: Class
type: NamedIndividual
type: Kind
subclass of: Object
subclass of: Entity
definition: A named stretch of time with defined bounds — a geologic era, historical dynasty, artistic period, fiscal year, or any other culturally salient temporal division.

certifier
type: ObjectProperty
type: FunctionalProperty
domain: Certification
range: Agent
definition: The agent that made a certification.

Tag
type: Class
type: NamedIndividual
type: Kind
subclass of: Information Object
definition: 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.

certified key
type: ObjectProperty
type: FunctionalProperty
domain: Certification
range: Cryptographic Key
definition: The cryptographic key a certification vouches for.

Proficiency Scale
type: Class
type: NamedIndividual
type: AbstractIndividualType
subclass of: QualityValue
definition: A framework for rating language proficiency (CEFR, ILR, ACTFL, self-reported). A value carried by gmeow:proficiencyScale and gmeow:levelScale.

Geocode
type: Class
type: NamedIndividual
type: Kind
subclass of: Entity
definition: 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.

Sortal
type: Class
subclass of: EndurantType
comment: A gufo:EndurantType which carries (or supplies) a principle of identity for its instances (see Guizzardi, 2005, chapter 4).

Web Page
type: Class
type: NamedIndividual
type: SubKind
subclass of: Creative Work
definition: A page on the web identified by a URL.

Software Name
type: Class
type: NamedIndividual
type: SubKind
subclass of: Appellation
definition: 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.

Logical Constraint
type: Class
type: NamedIndividual
type: Kind
subclass of: Constraint
subclass of: Restriction
  on property: constraint logic
  some values from: Constraint Logic
subclass of: Restriction
  on property: logic constraint member
  some values from: Constraint
definition: 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.

Trademark Status
type: Class
type: NamedIndividual
type: AbstractIndividualType
subclass of: QualityValue
definition: The registration status of a trademark — a VALUE: unregistered (™), registered (®), pending, expired, or cancelled. Open vocabulary.

Signature Scheme
type: Class
type: NamedIndividual
type: AbstractIndividualType
subclass of: QualityValue
definition: 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).

logic constraint member
type: ObjectProperty
domain: Logical Constraint
range: Constraint
definition: A member constraint combined by a logical constraint (odrl:operand). Non-functional: a logical constraint combines two or more.

Narrative Frame Link
type: Class
type: NamedIndividual
type: Kind
subclass of: Relator
definition: 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.

Route Kind
type: Class
type: NamedIndividual
type: AbstractIndividualType
subclass of: QualityValue
definition: 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.

assertion polarity
type: ObjectProperty
type: FunctionalProperty
domain: Accessibility Assertion
range: Accessibility Polarity
definition: Whether the assertion is a positive feature, a negative barrier, or a limited/partial status. Functional per relator: one polarity per AccessibilityAssertion.

containment child
type: ObjectProperty
type: FunctionalProperty
domain: Containment Tenure
range: Place
definition: The contained (child) place in this containment tenure. Functional: a tenure concerns exactly one child place.

Life Event
type: Class
type: NamedIndividual
type: EventType
subclass of: Event
definition: 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.

MaterialRelationshipType
type: Class
subclass of: RelationshipType
comment: A gufo:RelationshipType derived from extrinsic aspects of the related entities. For example, "marriedWith", "employedBy", "enrolledIn", "admires". For a gufo:MaterialRelationshipType it is recommended to identify the type of extrinsic aspect from which the material relationship type is derived (see gufo:isDerivedFrom). For example "marriedWith" can be derived from the "Marriage" relator type, "employedBy" can be derived from the "Employment" relator type. Encompasses "Material Relation" in Guizzardi (2005) and corresponds to "Material Relation" in Fonseca et al. (2019).

Pronoun Set
type: Class
type: NamedIndividual
type: Kind
subclass of: Information Object
definition: 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.

Verification Activity
type: Class
type: NamedIndividual
type: EventType
subclass of: Activity
definition: 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.

Agent
type: Class
type: NamedIndividual
type: Category
subclass of: FunctionalComplex
subclass of: Entity
disjoint with: Physical Object
definition: An entity that can act, bear responsibility, and enter into agreements: a person, an organization, or a software agent.

Pose
type: Class
type: NamedIndividual
type: Kind
subclass of: Object
subclass of: Entity
definition: 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.

Land Tenure
type: Class
type: NamedIndividual
type: SituationType
subclass of: Time-Scoped Relation
subclass of: Restriction
  on property: tenure party
  some values from: Agent
subclass of: Restriction
  on property: tenure place
  some values from: Place
definition: 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).

Occupancy
type: Class
type: NamedIndividual
type: SubKind
subclass of: Measurement
definition: 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.

left operand
type: ObjectProperty
type: FunctionalProperty
domain: Atomic Constraint
range: Left Operand
definition: The dimension an atomic constraint tests — one of the gmeow:LeftOperand values (odrl:leftOperand). Functional.

Sensory Environment
type: Class
type: NamedIndividual
type: Kind
subclass of: Object
subclass of: Entity
subclass of: Restriction
  on property: environment at location
  some values from: Location
definition: 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).

Observation Type
type: Class
type: NamedIndividual
type: AbstractIndividualType
subclass of: QualityValue
definition: 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.

hasReifiedQualityValue
type: ObjectProperty
domain: ConcreteIndividual
range: QualityValue
comment: Identifies an instance of gufo:QualityValue to reflect the perception or conception of a quality in a certain value space. Use this property only for quality values that are to be reified in the A-box and associated with a gufo:ConcreteIndividual. Otherwise, use the gufo:hasQualityValue data property and a literal to determine the quality value. The full representation pattern for quality values involves first identifying a gufo:Quality that inheres in a concrete individual and then associating it with a reified quality value. For example, let us consider the color of Yves Klein's "Blue Monochrome" painting made in 1961 (MoMA's object with number 618.1967). In the full pattern, an instance of gufo:Quality that inheres in the physical object (the color of that painting) is associated with a gufo:QualityValue (say the triplet <0, 47, 167> for that painting) through gufo:hasReifiedQualityValue. The full pattern is recommended when different quality spaces are expected to be used for the same quality. For example, the color of that painting could also be associated with a quadruple <100, 72, 0, 35> representing the same color in a CMYK space. When the full pattern is not required, gufo:hasReifiedQualityValue can also be used to directly associate a concrete individual (without identifying the quality) with a quality value.

hasQualityValue
type: DatatypeProperty
domain: ConcreteIndividual
comment: Determines a quality value associated with the concrete individual. Use gufo:hasReifiedQualityValue instead when quality values are reified. It is recommended that subproperties of gufo:hasQualityValue are created, possibly identifying the datatype to be used. For example, "hasTemperatureValue" could be defined as a sub-property of gufo:hasQualityValue whose domain is "Temperature" (specializing gufo:Quality) and whose range is xsd:double.

isSubQuantityOf
type: ObjectProperty
type: TransitiveProperty
sub property of: isObjectProperPartOf
domain: Quantity
range: Quantity
comment: Identifies a gufo:Quantity of which the quantity is a part. For example, the quantity of water in a wine glass is a sub-quantity of the wine in that glass. gufo:isSubQuantityOf is transitive (Guizzardi, 2005, p. 184). Sub-quantities are always essential parts of their wholes. Thus, gufo:standsInQualifiedParthood is not applicable for sub-quantities.

Mental Reference Frame
type: Class
type: NamedIndividual
type: SubKind
subclass of: Reference Frame
subclass of: Restriction
  on property: is hosted by
  some values from: Entity
definition: 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).

Sensory Perception
type: Class
type: NamedIndividual
type: SubKind
subclass of: Standpoint Claim
subclass of: Restriction
  on property: perception environment
  some values from: Sensory Environment
definition: 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).

Virtual Location
type: Class
type: NamedIndividual
type: SubKind
subclass of: Location
definition: 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.

is hosted by
type: ObjectProperty
domain: Reference Frame
range: Entity
definition: Relates a reference frame to the entity that hosts it — the entity whose existence bounds the frame's existence. A local grid is hosted by its building; a robot base frame by its robot; a mental reference frame by its perceiver (person, animal, or AI agent). When the host ceases to exist, the hosted frame deactivates (destruction event or existenceInterval end). Non-functional: contested authorship or multi-agent shared frames may have multiple host claims that coexist (Principle 9).

Individual
type: Class
disjoint with: Type
disjoint union of: AbstractIndividual
disjoint union of: ConcreteIndividual
comment: An entity that (unlike a gufo:Type) cannot be instantiated. Individuals may be either concrete (e.g., the Earth, Mick Jagger, Brazil, the 1985 Mexico City Earthquake) or abstract (e.g., the number two, the proposition that 'three is a prime number'). Also known as "particular" in the philosophical literature.

Certification
type: Class
type: NamedIndividual
type: Kind
subclass of: Relator
subclass of: Restriction
  on property: certified identity
  some values from: Agent
subclass of: Restriction
  on property: certified key
  some values from: Cryptographic Key
subclass of: Restriction
  on property: certifier
  some values from: Agent
definition: 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.

Constraint Operator
type: Class
type: NamedIndividual
type: AbstractIndividualType
subclass of: QualityValue
definition: The comparison operator of an atomic constraint — the ODRL operator vocabulary (eq, neq, lt, lteq, gt, gteq, isPartOf, isA, isAnyOf, …).

Honorific Class
type: Class
type: NamedIndividual
type: AbstractIndividualType
subclass of: QualityValue
definition: The domain of an honorific (academic, clerical, noble, military, judicial, social).

facet vantage
type: ObjectProperty
sub property of: vantage
domain: Observation
range: Agent
definition: The agent asserting an identity facet — the vantage of the claim. When gmeow:selfAsserted is true, the facetVantage is the person themselves (Principle 9: self-assertion is top authority).

Thread
type: Class
type: NamedIndividual
type: Kind
subclass of: Information Object
definition: A conversation: a set of messages related by reply/reference chains.

Import Activity
type: Class
type: NamedIndividual
type: EventType
subclass of: Activity
definition: 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.

Writing System
type: Class
type: NamedIndividual
type: Kind
subclass of: Information Object
definition: 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.

Event Type
type: Class
type: NamedIndividual
type: AbstractIndividualType
subclass of: QualityValue
definition: 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).

expression value
type: ObjectProperty
type: FunctionalProperty
domain: Gender Expression
range: Gender Expression Style
definition: The gmeow:GenderExpressionStyle value a gender-expression facet asserts (functional per facet). A predefined individual or a fresh one with rdfs:label; the single path to the value.

Membership
type: Class
type: NamedIndividual
type: Kind
subclass of: Relator
definition: The reified relationship by which an agent is a member of an organization, optionally playing a role over a period of time.

Cenozoic start age
type: NamedIndividual

TemporaryRelationshipSituation
type: Class
subclass of: Situation
subclass of: Restriction
  on property: concernsRelatedEndurant
  some values from: Endurant
subclass of: Restriction
  on property: concernsRelationshipType
  qualified cardinality: 1
  on class: RelationshipType
subclass of: Restriction
  on property:
    inverse of: standsInQualifiedRelationship
  qualified cardinality: 1
  on class: Endurant
comment: A gufo:Situation in which a gufo:Endurant temporarily stands in a relation with another gufo:Endurant (or other endurants in the case of n-ary relationships). Reification of a gufo:TemporaryRelationshipSituation allows qualification of the relationship with the period in time in which it applies. Examples include: the situation in which Einstein works at the Swiss Patent Office in Bern; the situation in which Elon Musk studies at the University of Pennsylvania; the situation in which John Lennon is married to Yoko Ono; and the situation in which Facebook has a lower market value than Amazon. For material relationships, prefer the use of gufo:Relator. This is a reification of the relationship (in a solution that is similar to the qualified relation pattern http://patterns.dataincubator.org/book/qualified-relation.html).

Online Account
type: Class
type: NamedIndividual
type: Kind
subclass of: Information Object
definition: An account an agent holds with an online service — a social profile, code-forge account, or decentralized identity.

Celestial Coordinates
type: Class
type: NamedIndividual
type: Kind
subclass of: Object
subclass of: Entity
definition: 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.

Standpoint Modality
type: Class
type: NamedIndividual
type: AbstractIndividualType
subclass of: QualityValue
definition: 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.

Entity
type: Class
type: NamedIndividual
type: Category
subclass of: Endurant
definition: 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.

Sensitivity Level
type: Class
type: NamedIndividual
type: AbstractIndividualType
subclass of: QualityValue
definition: 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).

Verification Result
type: Class
type: NamedIndividual
type: Kind
subclass of: Information Object
subclass of: Restriction
  on property: has verification status
  some values from: Verification Status
definition: 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).

jurisdiction place
type: ObjectProperty
type: FunctionalProperty
domain: Jurisdiction Tenure
range: Place
definition: The place whose governance is recorded by this JurisdictionTenure. Functional: a tenure concerns exactly one place (constitutive of the situation's identity).

AbstractIndividual
type: Class
subclass of: Individual
disjoint with: ConcreteIndividual
comment: A gufo:Individual that does not exist in space-time in the same way as a gufo:ConcreteIndividual does. A gufo:AbstractIndividual has no spatiotemporal qualities in its own right. Hence, it does not make sense to ask how much space it now occupies (Gideon, 2018) and when it was created or destroyed. Examples include the number ten, the null set, and the proposition that 'Obama was the president of the United States'. Rosen, Gideon, "Abstract Objects", The Stanford Encyclopedia of Philosophy (Winter 2018 Edition), Edward N. Zalta (ed.), <https://plato.stanford.edu/archives/win2018/entries/abstract-objects/>

Organization
type: Class
type: NamedIndividual
type: Kind
subclass of: Agent
definition: A structured group of agents — a company, institution, association, or governmental body — able to act as a single agent.

Place
type: Class
type: NamedIndividual
type: SubKind
subclass of: Location
definition: 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.

Gender
type: Class
type: NamedIndividual
type: AbstractIndividualType
subclass of: QualityValue
definition: 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.

Email Address
type: Class
type: NamedIndividual
type: SubKind
subclass of: Contact Point
definition: A contact point reachable via the Simple Mail Transfer Protocol (SMTP).

Sequence Coordinates
type: Class
type: NamedIndividual
type: Kind
subclass of: Object
subclass of: Entity
definition: 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).

Ledger Transaction
type: Class
type: NamedIndividual
type: Kind
subclass of: Information Object
subclass of: Restriction
  on property: transaction hash
  some values from: Literal
definition: A transaction recorded on a distributed ledger or blockchain — the information-object representation of the payload, not the on-chain bytes themselves.

Sex Assigned at Birth
type: Class
type: NamedIndividual
type: AbstractIndividualType
subclass of: QualityValue
definition: 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.

Verification Status
type: Class
type: NamedIndividual
type: AbstractIndividualType
subclass of: QualityValue
definition: The outcome status of a verification result — a value vocabulary (individuals, never subclasses).

Version Role
type: Class
type: NamedIndividual
type: AbstractIndividualType
subclass of: QualityValue
definition: 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.

Geometry Type
type: Class
type: NamedIndividual
type: AbstractIndividualType
subclass of: QualityValue
definition: 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.).

Gender Expression
type: Class
type: NamedIndividual
type: SubKind
subclass of: Identity Facet
subclass of: Restriction
  on property: expression value
  some values from: Gender Expression Style
definition: 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.

IntrinsicAspect
type: Class
subclass of: Aspect
subclass of: Restriction
  on property: inheresIn
  qualified cardinality: 1
  on class: ConcreteIndividual
disjoint union of: IntrinsicMode
disjoint union of: Quality
comment: A gufo:Aspect that depends on a single concrete individual in which it inheres. Examples include intrinsic physical aspects, such as the Moon's mass, Lassie's fur color; the fragility of John Lennon's glasses; mental dispositions, such as Bob's math skills, his belief that the number one is odd. A gufo:IntrinsicAspect is classified as a gufo:Quality (e.g., an apple's weight, the height of the Statue of Liberty) if it is measurable by a certain value space, or as a gufo:IntrinsicMode (e.g. Bob's belief that the Eiffel Tower is in Paris) otherwise. Corresponds to "Intrinsic Moment" in Guizzardi (2005). Different from Guizzardi (2005), here we consider that aspects can inhere in concrete individuals in general, and not only in endurants.

Frame Realm
type: Class
type: NamedIndividual
type: AbstractIndividualType
subclass of: QualityValue
definition: The physical, virtual, or conceptual domain of a reference frame (e.g. terrestrial, indoor, celestial, virtual, measurement, currency, temporal, colourspace, linguistic).

log entry index
type: DatatypeProperty
type: FunctionalProperty
domain: Transparency Log Entry
range: integer
definition: The sequential index of the entry within its transparency log.

trustee
type: ObjectProperty
type: FunctionalProperty
domain: Trust Assertion
range: Agent
definition: The agent that is trusted by the trustor in a trust-assertion.

Name Usage
type: Class
type: NamedIndividual
type: SubKind
subclass of: Relator
subclass of: Observation
subclass of: Restriction
  on property: usage appellation
  some values from: Appellation
subclass of: Restriction
  on property: usage named
  some values from: Entity
definition: 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.

Email Message
type: Class
type: NamedIndividual
type: SubKind
subclass of: Message
definition: An RFC 5322 email message, with headers, participants, a thread, body parts and mailbox residence.

Sexual Orientation Value
type: Class
type: NamedIndividual
type: AbstractIndividualType
subclass of: QualityValue
definition: 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.

Spatial Coordinates
type: Class
type: NamedIndividual
type: Kind
subclass of: Object
subclass of: Entity
definition: A set of coordinate values representing a position in a specific coordinate reference frame.

Language Proficiency
type: Class
type: NamedIndividual
type: Kind
subclass of: Relator
definition: 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.

QualityValueAttributionSituation
type: Class
subclass of: Situation
subclass of: Class
  union of: Restriction
    on property: concernsReifiedQualityValue
    qualified cardinality: 1
    on class: QualityValue
  union of: Restriction
    on property: concernsQualityValue
    cardinality: 1
subclass of: Restriction
  on property: concernsQualityType
  qualified cardinality: 1
  on class: EndurantType
subclass of: Restriction
  on property:
    inverse of: standsInQualifiedAttribution
  qualified cardinality: 1
  on class: Endurant
disjoint with: TemporaryConstitutionSituation
disjoint with: TemporaryInstantiationSituation
disjoint with: TemporaryParthoodSituation
disjoint with: TemporaryRelationshipSituation
comment: A gufo:Situation in which a quality value is temporarily attributed to a gufo:Endurant. A gufo:QualityValueAttributionSituation should be used only for mutable qualities, i.e. those whose value can vary in time. Examples include: the situation in which the value of a bitcoin in Euros is 6.526,12, which lasted from 10/12/2019 to 11/12/2019; the situation in which the weight of Mike Tyson was 100 kg; and the situation in which the color of Einstein' hair was grey. This is a reification of the quality value attribution (in a solution that is similar to the qualified relation pattern http://patterns.dataincubator.org/book/qualified-relation.html )

Transparency Log Entry
type: Class
type: NamedIndividual
type: Kind
subclass of: Information Object
subclass of: Restriction
  on property: log entry index
  some values from: integer
subclass of: Restriction
  on property: log entry URL
  some values from: Literal
definition: 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).

relationship parent
type: ObjectProperty
type: FunctionalProperty
sub property of: observed feature
domain: Parent-Child Relationship
range: Person
definition: The parent in a reified parent-child relationship.

Capacity
type: Class
type: NamedIndividual
type: SubKind
subclass of: Measurement
definition: 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).

event location
type: ObjectProperty
domain: Event
range: Location
property chain axiom: contained in location
definition: A location at which an event occurred — a geographic gmeow:Place, a gmeow:VirtualLocation, or any other gmeow:Location (the full superset). Non-functional: an event may span several locations, and competing standpoint-indexed locations coexist.

has ancestor
type: ObjectProperty
type: TransitiveProperty
inverse of: has descendant
domain: Person
range: Person
definition: Relates a person to an ancestor — a parent, a parent's parent, and so on. Transitive: an ancestor of an ancestor is an ancestor. gmeow:hasParent (hence gmeow:hasMother / hasFather) is a sub-property, so ancestry is DERIVED from parentage by the reasoner and is never asserted directly.

FunctionalComplex
type: Class
subclass of: Object
comment: isComponentOf
comment: A complex gufo:Object whose parts (components) play different roles in its composition. For example, a person could be considered a gufo:FunctionalComplex with the various organs (heart, brain, lungs, etc.) playing different roles. Another example is a scrum team, which is composed by people playing the roles of scrum master, product owner, developer, etc. To explicitly capture temporary components, use gufo:TemporaryParthoodSituation.

isComponentOf
type: ObjectProperty
sub property of: isObjectProperPartOf
domain: Object
range: FunctionalComplex
comment: Identifies a gufo:FunctionalComplex of which the object is a component. For example, the habitation module is a component of the International Space Station, and so are each of the solar panels; Obama's brain is a component of his body, and so is his heart; the engine is a component of the HMS Queen Elizabeth (R08). gufo:isComponentOf is not transitive in the general case. Particular sub-properties may be transitive (Guizzardi, 2005, p. 183). When a component may change its relation to be whole, see gufo:standsInQualifiedParthood.

Location State
type: Class
type: NamedIndividual
type: Kind
subclass of: Object
subclass of: Entity
definition: The state of a moving entity at a specific point or period in time, including its location, velocity, and pose (position + orientation).

Time Interval
type: Class
type: NamedIndividual
type: AbstractIndividualType
subclass of: AbstractIndividual
definition: A bounded stretch of time, optionally open-ended, delimited by a start and/or end instant.

Network Address
type: Class
type: NamedIndividual
type: Kind
subclass of: Entity
definition: 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.

Rights Type
type: Class
type: NamedIndividual
type: AbstractIndividualType
subclass of: QualityValue
definition: 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.

Kin Relationship
type: Class
type: NamedIndividual
type: SubKind
subclass of: Relator
subclass of: Observation
definition: 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.

Time-Scoped Relation
type: Class
type: NamedIndividual
type: SituationType
subclass of: Situation
definition: A reified relationship that holds only over a particular time interval — the base for residence, tenure, and membership-over-time situations.

Role
type: Class
type: NamedIndividual
type: RoleMixin
subclass of: FunctionalComplex
definition: A function or position an agent plays in some context, such as a job title or organizational role.

Stream
type: Class
type: NamedIndividual
type: Kind
subclass of: Object
subclass of: Entity
subclass of: Restriction
  on property: stream of
  some values from: Entity
definition: 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.

perception environment
type: ObjectProperty
type: FunctionalProperty
sub property of: observed feature
domain: Observation
range: Sensory Environment
definition: The SensoryEnvironment that a SensoryPerception is about — the observedFeature of the claim. Domain is gmeow:Observation so it applies to any observation subclass; the shape narrows to SensoryPerception instances.

Occupation
type: Class
type: NamedIndividual
type: Kind
subclass of: Entity
definition: A kind of work or profession, such as those classified by ESCO or SOC.

Duty
type: Class
type: NamedIndividual
type: Kind
subclass of: Rule
definition: 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).

relationship child
type: ObjectProperty
type: FunctionalProperty
sub property of: observed feature
domain: Parent-Child Relationship
range: Person
definition: The child in a reified parent-child relationship.

Writing System Type
type: Class
type: NamedIndividual
type: AbstractIndividualType
subclass of: QualityValue
definition: The structural kind of a writing system (alphabet, abjad, abugida, syllabary, logographic, featural, ideographic, pictographic, non-linear, mixed). A value carried by gmeow:writingSystemType.

transaction hash
type: DatatypeProperty
type: FunctionalProperty
domain: Ledger Transaction
range: Literal
definition: The hash of a ledger transaction.

EventType
type: Class
subclass of: ConcreteIndividualType
disjoint with: SituationType
comment: A gufo:Type whose instances are events. Instances of gufo:EventType are subclasses of gufo:Event. Examples include "Business Meeting", "Birth", "Musical Performance".

Proficiency Modality
type: Class
type: NamedIndividual
type: AbstractIndividualType
subclass of: QualityValue
definition: The skill channel a language proficiency rates (speaking, listening, reading, writing, signing, comprehension, overall). A value carried by gmeow:proficiencyModality.

Participation
type: Class
type: NamedIndividual
type: Kind
subclass of: Relator
subclass of: Restriction
  on property: participation event
  some values from: Event
subclass of: Restriction
  on property: participation participant
  some values from: Entity
definition: 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.

containment parent
type: ObjectProperty
type: FunctionalProperty
domain: Containment Tenure
range: Place
definition: The containing (parent) place in this containment tenure. Functional: a single tenure has exactly one parent place.

Regulatory Overlay
type: Class
type: NamedIndividual
type: SituationType
subclass of: Time-Scoped Relation
subclass of: Restriction
  on property: overlay authority
  some values from: Agent
subclass of: Restriction
  on property: overlay place
  some values from: Place
definition: 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).

Trust Assertion
type: Class
type: NamedIndividual
type: Kind
subclass of: Relator
subclass of: Restriction
  on property: trustee
  some values from: Agent
subclass of: Restriction
  on property: trustor
  some values from: Agent
definition: 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.

rcc8 dc
type: ObjectProperty
type: SymmetricProperty
domain: Location
range: Location
definition: RCC-8: Disconnected (DC) — regions are disjoint and do not share any point.

participant address
type: ObjectProperty
type: FunctionalProperty
domain: Message Participant
range: Email Address
definition: The normalized email address that appears in this participant occurrence.

Blockchain Network
type: Class
type: NamedIndividual
type: Kind
subclass of: Entity
subclass of: Restriction
  on property: chain id
  some values from: Literal
definition: A blockchain network identified by a chain identifier (e.g. CAIP-2 chainId).

facet subject
type: ObjectProperty
sub property of: observed feature
domain: Observation
range: Person
definition: The person an identity facet (gender identity, gender expression, sexual/romantic orientation) is about — the observedFeature of the claim. Domain is gmeow:Observation so it applies to any observation subclass; the shape narrows to IdentityFacet instances.

Attestation Policy
type: Class
type: NamedIndividual
type: AbstractIndividualType
subclass of: QualityValue
definition: The policy or framework under which an attestation was issued — a value vocabulary (individuals, never subclasses). Open-ended; specific policies are minted as needed.

Person
type: Class
type: NamedIndividual
type: Kind
subclass of: Agent
definition: An individual human being, living or deceased.

AntiRigidType
type: Class
subclass of: NonRigidType
disjoint with: SemiRigidType
comment: A gufo:NonRigidType that applies contingently to all its instances (see Guizzardi, 2005, chapter 4). Examples include the gufo:Phase "Child", the gufo:PhaseMixin "InfantAnimal", the gufo:Role "Student", and the gufo:RoleMixin "Customer".

has verification status
type: ObjectProperty
domain: Verification Result
range: Verification Status
definition: The categorical outcome of a verification result. Non-functional: a single result may carry multiple status interpretations (e.g. 'verified but expired').

Tagging
type: Class
type: NamedIndividual
type: Kind
subclass of: Relator
subclass of: Restriction
  on property: tagging tag
  some values from: Tag
subclass of: Restriction
  on property: tagging tagged
  some values from: Entity
subclass of: Restriction
  on property: tagging tagger
  some values from: Agent
definition: 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.

Frame Kind
type: Class
type: NamedIndividual
type: AbstractIndividualType
subclass of: QualityValue
definition: The structural type of a reference frame (e.g. geodetic, Cartesian, polar, grid, narrative).

Sequence Feature
type: Class
type: NamedIndividual
type: Kind
subclass of: Object
subclass of: Entity
definition: 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.

Parent-Child Relationship
type: Class
type: NamedIndividual
type: SubKind
subclass of: Kin Relationship
subclass of: Restriction
  on property: relationship child
  some values from: Person
subclass of: Restriction
  on property: relationship parent
  some values from: Person
definition: A reified parent-child relationship, typed by its nature (biological, adoptive, step, or foster).

Route
type: Class
type: NamedIndividual
type: Kind
subclass of: Entity
definition: 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.

Quantity
type: Class
subclass of: Object
comment: A complex gufo:Object that is a maximally-connected portion of stuff. A gufo:Quantity has a fixed constitution, and thus, removing or adding a sub-quantity would result in a different quantity. Examples include the portion of wine in a wine tank, a lump of clay, the gold that constitutes a wedding ring. Also termed "quantity of matter", "objectified portion of matter", "piece" in the philosophical literature.

SemiRigidType
type: Class
subclass of: NonRigidType
comment: A gufo:NonRigidType that applies necessarily to some of its instances and contingently to some others (see Guizzardi, 2005, chapter 4).

Quality
type: Class
subclass of: IntrinsicAspect
comment: A gufo:IntrinsicAspect that is measurable by some value spaces. A quality may be used to compare individuals, on the basis of the value it takes in a certain quality space (for instance, a position within the RGB spectrum). Examples include the weight of a person, the name of organization, the color of a car, and the duration of a concert.

Sequence Feature Type
type: Class
type: NamedIndividual
type: AbstractIndividualType
subclass of: QualityValue
definition: 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).

IntrinsicMode
type: Class
subclass of: IntrinsicAspect
disjoint with: Quality
comment: A gufo:IntrinsicAspect that is not measurable. For example, Bob's belief that the Eiffel Tower is in Paris, his math skills, his headache. Corresponds to "Mode" in Guizzardi (2005).

Transliteration Scheme
type: Class
type: NamedIndividual
type: AbstractIndividualType
subclass of: QualityValue
definition: 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).

Proficiency Level
type: Class
type: NamedIndividual
type: AbstractIndividualType
subclass of: QualityValue
definition: 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.

Quality Assessment
type: Class
type: NamedIndividual
type: SubKind
subclass of: Observation
subclass of: Restriction
  on property: assessed entity
  some values from: Entity
definition: 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).

QualityValue
type: Class
subclass of: AbstractIndividual
comment: A gufo:AbstractIndividual that can be associated with a gufo:Quality reflecting the perception or conception of the quality in a certain value space. Instances of gufo:QualityValue include the rational number 2.5 when used to conceive of the acidity of a portion of wine (in a pH scale), the tuple <38.8897,-77.0089> when used to conceive of the location of a building (in a space formed by latitude and longitude), or the triplet <0,0,0> when used to conceive of the color of a physical object (in a trimensional space formed by red, green and blue color components). Corresponds to "Quale" in Guizzardi (2005). Use this class only for quality values (qualia) that are to be reified in the A-box and associated with a gufo:ConcreteIndividual through the object property gufo:hasReifiedQualityValue. Otherwise, use the gufo:hasQualityValue data property and a literal to determine the quality value.

artifact media type
type: DatatypeProperty
type: FunctionalProperty
domain: Attestation Artifact
range: Literal
definition: The media type of the attestation artifact's serialization (e.g. application/vnd.in-toto+json, application/vc+ld+json).

Event Series
type: Class
type: NamedIndividual
type: Kind
subclass of: Entity
definition: 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.

Aggregation Function
type: Class
type: NamedIndividual
type: AbstractIndividualType
subclass of: QualityValue
definition: The kind of statistical aggregation applied to a spatial region — a value vocabulary (individuals, never subclasses).

NonRigidType
type: Class
subclass of: EndurantType
disjoint with: RigidType
disjoint union of: AntiRigidType
disjoint union of: SemiRigidType
comment: A gufo:EndurantType that does not apply necessarily to at least one of its instances (see Guizzardi, 2005, chapter 4). Examples include anti-rigid types, such as the role "Student" and the phase "Child", and semi-rigid types, such as the mixin "MusicalArtist" (which necessarily characterizes bands, but contingently characterizes people) and the mixin "FemaleAnimal" (which is necessarily characterizes female dogs, but contigently characterizes clownfish).

certified identity
type: ObjectProperty
type: FunctionalProperty
domain: Certification
range: Agent
definition: The agent identity a certification binds the key to.

Relay Hop
type: Class
type: NamedIndividual
type: EventType
subclass of: Event
definition: 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.

Formal Language
type: Class
type: NamedIndividual
type: SubKind
subclass of: Language
definition: 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.

Name Part Type
type: Class
type: NamedIndividual
type: AbstractIndividualType
subclass of: QualityValue
definition: 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.

tagging tagged
type: ObjectProperty
type: FunctionalProperty
domain: Tagging
range: Entity
definition: The entity that is tagged in a tagging act. Functional per relator: one tagged entity per Tagging.

Instant
type: Class
subclass of: AbstractIndividual
comment: An gufo:AbstractIndividual that reifies time instants. It is used as a target of the gufo:hasBeginPoint and gufo:hasEndPoint object properties.

Romantic Orientation
type: Class
type: NamedIndividual
type: SubKind
subclass of: Identity Facet
subclass of: Restriction
  on property: romantic orientation value
  some values from: Romantic Orientation Value
definition: 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).

Citation
type: Class
type: NamedIndividual
type: Kind
subclass of: Information Object
definition: A reference to a specific place within a source (a page, entry, image, or record locator).

chain id
type: DatatypeProperty
type: FunctionalProperty
domain: Blockchain Network
range: Literal
definition: The chain identifier of a blockchain network (e.g. CAIP-2 chainId, eip155:1).

Profile
type: Class
type: NamedIndividual
type: Kind
subclass of: Object
subclass of: Information Object
definition: 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.

standpoint claim
type: ObjectProperty
type: FunctionalProperty
domain: Standpoint Tenure
range: Standpoint Claim
definition: The StandpointClaim observation that a StandpointTenure generates — the reified observation of the tenure's time-scoped fact. The tenure is the time-scoped situation; the claim is the observation of that fact. Functional: a tenure generates exactly one claim.

ConcreteIndividual
type: Class
subclass of: Individual
disjoint union of: Endurant
disjoint union of: Event
disjoint union of: Situation
comment: A gufo:Individual that exists in space-time. Concrete individuals comprise not only object-like entities (a car, a mountain, a person, a marriage, a belief), but also events (a business meeting, a soccer match) and situations (the situation in which a person weighs 80 kilograms, the situation in which a bank account is overdrawn).

Software Project
type: Class
type: NamedIndividual
type: SubKind
subclass of: Creative Work
definition: A software project: a body of source code developed and released as a unit, with repositories, releases, and contributors.

Strand Orientation
type: Class
type: NamedIndividual
type: AbstractIndividualType
subclass of: QualityValue
definition: 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.

Writing System Usage
type: Class
type: NamedIndividual
type: Kind
subclass of: Relator
definition: 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.

trademark mark
type: ObjectProperty
type: FunctionalProperty
domain: Trademark
range: Mark
definition: The mark a trademark protects. Functional.

RelationshipType
type: Class
subclass of: Type
comment: A gufo:Type whose instances are ordered pairs of related entities. Instances of gufo:RelationshipType are object properties in UFO-based ontologies. The object properties "marriedWith" and "enrolledIn" are examples of material relationship types. The object properties "heavierThan", "olderThan" are examples of comparative relationship types. The use of gufo:RelationshipType and its subclasses requires OWL 2 punning. Corresponds to "Relation" in Guizzardi (2005) and Fonseca et al. (2019).

Mailbox Residence
type: Class
type: NamedIndividual
type: SituationType
subclass of: Time-Scoped Relation
definition: 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).

Celestial Location
type: Class
type: NamedIndividual
type: SubKind
subclass of: Location
definition: 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).

Determinacy
type: Class
type: NamedIndividual
type: AbstractIndividualType
subclass of: QualityValue
definition: 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.

Aspect
type: Class
subclass of: Endurant
disjoint with: Object
disjoint union of: ExtrinsicAspect
disjoint union of: IntrinsicAspect
comment: A gufo:Endurant that depends on at least one other concrete individual for its existence. A gufo:Aspect is a characteristic or trait of a concrete individual that is itself conceived as an individual. Examples include: intrinsic physical aspects, such as the Moon's mass, Lassie's fur color; mental dispositions, such as Bob's math skills, his belief that the number one is odd; as well as relational aspects, such as John's love for Mary and the marriage between John and Mary. The specific sort of existential dependence connecting aspects to their bearers is called inherence. Corresponds to "Moment" in Guizzardi (2005). Also termed "property instance", "particularized property", "individual accident", or "(variable) trope" in the philosophical literature.

romantic orientation value
type: ObjectProperty
type: FunctionalProperty
domain: Romantic Orientation
range: Romantic Orientation Value
definition: The gmeow:RomanticOrientationValue a romantic-orientation facet asserts (functional per facet). A predefined individual or a fresh one with rdfs:label; the single path to the value.

Event
type: Class
type: NamedIndividual
type: EventType
subclass of: Event
definition: 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.

constraint logic
type: ObjectProperty
type: FunctionalProperty
domain: Logical Constraint
range: Constraint Logic
definition: The boolean operator combining a logical constraint's members — one of the gmeow:ConstraintLogic values (odrl:and / or / xone / andSequence). Functional.

premises / address point
type: NamedIndividual
type: Place Type

Spatial Bin
type: Class
type: NamedIndividual
type: SubKind
subclass of: Place
definition: 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.

copyright work
type: ObjectProperty
type: FunctionalProperty
domain: Copyright
range: Information Object
definition: The work a copyright protects. Functional: one copyright relator is about one work.

Reference Position
type: Class
type: NamedIndividual
type: Kind
subclass of: Object
subclass of: Entity
definition: 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.

Utilization
type: Class
type: NamedIndividual
type: SubKind
subclass of: Measurement
definition: 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.

Interpersonal Relationship
type: Class
type: NamedIndividual
type: Kind
subclass of: Relator
subclass of: Restriction
  on property: relationship party
  some values from: Agent
definition: A reified standing relationship between agents (acquaintance, collaboration, …), able to bear its own time interval, confidence, and source evidence.

Privacy Notice
type: Class
type: NamedIndividual
type: Kind
subclass of: Information Object
definition: 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.

standsInQualifiedRelationship
type: ObjectProperty
sub property of: standsIn
domain: Endurant
range: TemporaryRelationshipSituation
comment: Identifies a gufo:TemporaryRelationshipSituation in which the endurant stands. The identified gufo:TemporaryRelationshipSituation is then used with the gufo:concernsRelatedEndurant and the gufo:concernsRelationshipType object properties to indicate the related element and the type of relationship that applies. This forms a pattern to represent that relationships that may change in different situations. For example, "heavierThan" may change when the objects involved gain or lose weight. For material relations, prefer the use of gufo:Relator.

rule action
type: ObjectProperty
type: FunctionalProperty
domain: Rule
range: Rights Action
definition: The regulated action of a rule — one of the open gmeow:RightsAction values (odrl:action). Functional: a rule regulates exactly one action; several actions are several rules.

Message Participant
type: Class
type: NamedIndividual
type: Kind
subclass of: Relator
subclass of: Restriction
  on property: participant address
  some values from: Email Address
subclass of: Restriction
  on property: participant message
  some values from: Email Message
subclass of: Restriction
  on property: participant role
  some values from: Message Participant Role
definition: A reified occurrence of an email address in a particular message header or envelope context.

Object
type: Class
subclass of: Endurant
comment: A gufo:Endurant that does not depend on another endurant for its existence (excluding its essential parts and aspects). Examples of objects include ordinary physical entities, such as a dog, a house, a tomato, a car, Alan Turing, but also socially-defined entities such as The Rolling Stones, the European Union, the Brazilian 1988 Constitution. Guizzardi (2005) also included the more abstract notion of "Substantial", which generalizes both objects and amounts of matter. That notion was left out from this implementation, together with the notion of amount of matter. Support for the representation of maximally-self-connected amounts of matter is given by gufo:Quantity.

trustor
type: ObjectProperty
type: FunctionalProperty
domain: Trust Assertion
range: Agent
definition: The agent whose (subjective) trust a trust-assertion expresses — the perspective holder.

SubKind
type: Class
subclass of: RigidType
subclass of: Sortal
comment: A gufo:EndurantType that is both sortal and rigid. It specializes a gufo:Kind carrying the principle of identity supplied by that kind. Every gufo:SubKind should directly or indirectly specialize a gufo:Kind. For example, the gufo:Kind "Lion" may be specialized into the "Lionness" and "Male Lion" subkinds, while the gufo:Kind "Computer" may be specialized into the "Laptop" and "Desktop" subkinds.

Proximity Measurement
type: Class
type: NamedIndividual
type: SubKind
subclass of: Measurement
definition: 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.

was attributed to
type: ObjectProperty
domain: Entity
range: Agent
definition: Ascribes responsibility for an entity to an agent.

Creative Work Title
type: Class
type: NamedIndividual
type: SubKind
subclass of: Appellation
definition: 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.

Message Keyword
type: Class
type: NamedIndividual
type: AbstractIndividualType
subclass of: QualityValue
definition: A flag/keyword applied to a message (IMAP flag or JMAP keyword) such as seen, flagged, answered, draft, forwarded, or junk.

geologic era
type: NamedIndividual
type: Period Type

tenure place
type: ObjectProperty
type: FunctionalProperty
domain: Land Tenure
range: Place
definition: The place (parcel, lot, or spatial unit) over which the rights of this LandTenure apply. Functional: a tenure concerns exactly one place (constitutive of the situation's identity).

Mark
type: Class
type: NamedIndividual
type: Kind
subclass of: Information Object
definition: 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).

Attestation Type
type: Class
type: NamedIndividual
type: AbstractIndividualType
subclass of: QualityValue
definition: 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.

Cryptographic Signature
type: Class
type: NamedIndividual
type: Kind
subclass of: Information Object
definition: A cryptographic signature over a message or its headers, asserting origin and integrity.

Collection
type: Class
subclass of: Object
disjoint union of: FixedCollection
disjoint union of: VariableCollection
comment: A complex gufo:Object whose parts (the members of the collection) have a uniform structure (i.e., members are conceived as playing the same role in the collection). Collections may have a fixed or variable membership, which can be asserted using gufo:FixedCollection and gufo:VariableCollection respectively. Examples include a deck of cards, a pile of bricks, a forest (conceived as a collection of trees), and a group of people. Collections in many cases constitute a functional complex. For example, a pile of bricks may constitute a wall, a group of people may constitute a football team. A gufo:Collection may be decomposed into "smaller" collections. For instance, a group of people may be decomposed into a group of English speakers and a group of Italian speakers. Sub collections may or may not share members among them.

has temporal measurement
type: ObjectProperty
range: Temporal Measurement
definition: Relates an entity (event, artifact, place, sample) to a temporal measurement assigned to it.

Instant
type: Class
type: NamedIndividual
type: AbstractIndividualType
subclass of: AbstractIndividual
definition: 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.

standsInQualifiedInstantiation
type: ObjectProperty
sub property of: standsIn
domain: Endurant
range: TemporaryInstantiationSituation
comment: Identifies a gufo:TemporaryInstantiationSituation in which the endurant stands. The identified gufo:TemporaryInstantiationSituation is further related with a gufo:NonRigidType through the gufo:concernsNonRigidType object property. This forms a pattern to represent the contigent instantiation of a non-rigid type by the endurant, in which case instantiation may vary in different situations.

Couple Relationship
type: Class
type: NamedIndividual
type: SubKind
subclass of: Kin Relationship
definition: A reified couple relationship (marriage, civil union, or partnership) between two persons; bears marriage, divorce and related events.

constraint operator
type: ObjectProperty
type: FunctionalProperty
domain: Atomic Constraint
range: Constraint Operator
definition: The comparison operator of an atomic constraint — one of the gmeow:ConstraintOperator values (odrl:operator). Functional.

Situation
type: Class
subclass of: ConcreteIndividual
comment: A gufo:ConcreteIndividual that is a particular configuration of a part of reality which can be understood as a whole and in which entities stand in relations. A situation may be counterfactual or actual. An actual situation (or in other words, a "fact") "obtains" in a certain time instant or during a time interval. Note that, in Guizzardi et al. (2013), situations were considered to obtain at a specific point in time. Here, instead, they obtain in a time interval when begin and end points differ. The various subclasses of Situation in this implementation are used to capture "mutable" facts which obtain during some time and fail to obtain at other times. This includes the contingent instantiation of non-rigid types (e.g., as someone is a child at one point in time and a teenager later), the attribution of value to mutable qualities (such as a person's weight) and temporary participation in part-whole relations for replaceable parts (such as a car's tires). Other subclasses may be created to capture domain-specific notions such as "HazardousSituation", "PersonHasFever".

participant role
type: ObjectProperty
type: FunctionalProperty
domain: Message Participant
range: Message Participant Role
definition: The header or envelope role of this address occurrence.

block hash
type: DatatypeProperty
type: FunctionalProperty
domain: Block
range: Literal
definition: The hash of a ledger block.

region / state / province
type: NamedIndividual
type: Place Type

Script Role
type: Class
type: NamedIndividual
type: AbstractIndividualType
subclass of: QualityValue
definition: 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.

geometry result
type: ObjectProperty
sub property of: observation result
domain: Coordinate Observation
range: Geometry
definition: The Geometry result of a coordinate observation — a point, line, or polygon expressed as WKT or GeoJSON. The reference frame is carried on the observation and propagates to the result via the existing property chain.

attester
type: ObjectProperty
type: FunctionalProperty
domain: Attestation
range: Agent
definition: The agent that issued an attestation — the vouching party. Functional within the relator: one attester per Attestation (co-authorship is modelled as multiple Attestations).

SituationType
type: Class
subclass of: ConcreteIndividualType
comment: A gufo:Type whose instances are situations. Instances of gufo:SituationType are subclasses of gufo:Situation. Examples include "HazardousSituation", "PersonHasFever", "PersonIsStudent".

Physical Object
type: Class
type: NamedIndividual
type: Category
subclass of: Object
subclass of: Entity
definition: 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.

Category
type: Class
subclass of: NonSortal
subclass of: RigidType
comment: A gufo:EndurantType that is both non-sortal and rigid. It captures essential properties that apply to instances of different kinds. For example, "PhysicalObject" may be considered a gufo:Category, encompassing objects such as cars, planets, trees. "Agent" may be a gufo:Category that classifies both people and organizations.

geologic eon
type: NamedIndividual
type: Period Type

standsInQualifiedAttribution
type: ObjectProperty
sub property of: standsIn
domain: Endurant
range: QualityValueAttributionSituation
comment: Identifies a gufo:QualityValueAttributionSituation in which the endurant stands. The identified gufo:QualityValueAttributionSituation is then used with the gufo:concernsQualityValue data property or the gufo:concernsReifiedQualityValue object property to indicate a quality value attributed to the gufo:Endurant standing in the situation. This forms a pattern to represent that quality values may differ in different situations.

supersedes
type: ObjectProperty
domain: Entity
range: Entity
definition: Relates a newer entity, version, record, or claim-bearing artifact to a prior one it supersedes. Non-functional: one successor may consolidate several predecessors. Superseded entities remain first-class and usable; suppression from display is handled separately with gmeow:displayable false when appropriate.

Virtual Location Type
type: Class
type: NamedIndividual
type: AbstractIndividualType
subclass of: QualityValue
definition: 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).

Accessibility Facet
type: Class
type: NamedIndividual
type: AbstractIndividualType
subclass of: QualityValue
definition: 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.

VariableCollection
type: Class
subclass of: Collection
comment: TemporaryParthoodSituation
comment: A gufo:Collection for which change in membership is possible. Such a collection obeys an intensional principle of identity, i.e., change in membership does not necessarily create a different collection. For example, KLM's fleet of airplanes could be understood as a gufo:VariableCollection. In this case, when the company acquires (or retires) an airplane, the fleet changes. Note that, in this case, the airplanes are conceptualized as playing the role of "member of a fleet". If various roles for the parts of a fleet were envisioned (such as "cargo airplane", "passenger airplane"), then a fleet would be best understood as a gufo:FunctionalComplex. See gufo:TemporaryParthoodSituation for the pattern to represent the relation of a variable collection to its temporary parts.

Activity
type: Class
type: NamedIndividual
type: EventType
subclass of: Event
definition: Something that occurs over a period of time and acts upon or with entities — creating, transforming, using, or attributing them.

AbstractIndividualType
type: Class
subclass of: Type
disjoint with: ConcreteIndividualType
disjoint with: RelationshipType
comment: A gufo:Type whose instances are abstract individuals. Instances of gufo:AbstractIndividualType are subclasses of gufo:AbstractIndividual. Examples include the types "NaturalNumber", "Set", "Proposition".

NonSortal
type: Class
subclass of: EndurantType
disjoint with: Sortal
comment: A gufo:EndurantType that applies to individuals of different kinds (see Guizzardi, 2005, chapter 4). Non-sortals do not provide a uniform principle of identity for their instances; instead, they just classify things that share common properties but which obey different principles of identity. Also termed "dispersive" types in the philosophical literature.

concernsRelatedEndurant
type: ObjectProperty
type: FunctionalProperty
domain: TemporaryRelationshipSituation
range: Endurant
comment: Identifies the related gufo:Endurant in the gufo:TemporaryRelationshipSituation.

Type
type: Class
comment: An entity that may be instantiated by (or predicated over) other entities. Types encompass what we often call "sorts", "kinds", "categories", etc. Examples include the kind "Person", the event type "Earthquake", and the abstract individual type "NaturalNumber". Relations, such as "marriedTo" and "olderThan", are also considered as types. Instances of gufo:Type are classes, and should specialize the taxonomy of individuals of gUFO. For example, "Person" is a gufo:Type (more specifically a gufo:Kind), specializing gufo:Object. The mechanism that allows for this is called punning in OWL 2. Encompasses the notion of "Universal" in Guizzardi (2005).
