Identity Aspects

Identity, and classification, are important in many ontologies; for example, we make use of IRIs to identify classes and property definitions in our ontologies and classify classes and properties as SKOS concepts as appropriate. In this section we provide the ability to define schemes which describe the namespace, rules, and authority for a set things and then go on to define classifier and identifier schemes.

Classes

Classification scheme

Definition:

A classification scheme provides a reference and scope for a set of classifiers.

OWL:

fnd:ClassificationScheme a owl:Class ;
  rdfs:subClassOf fnd:Scheme ;
  skos:prefLabel "Classification scheme"@en ;
  skos:definition "..."@en .

Classified thing

Definition:

A thing to which classifiers have been/may be attached.

OWL:

fnd:ClassifiedThing a owl:Class ;
  rdfs:subClassOf fnd:Thing ;
  skos:prefLabel "Classified thing"@en ;
  skos:definition "..."@en .

Classifier

Definition:

A classifier is used to denote a group to which one more things belongs, within some classification scheme.

OWL:

fnd:Classifier a owl:Class ;
  rdfs:subClassOf fnd:Reference ;
  skos:prefLabel "Classifier"@en ;
  skos:definition "..."@en .

Functional identifier

Definition:

TBD

OWL:

fnd:FunctionalIdentifier a owl:Class ;
  rdfs:subClassOf fnd:Identifier ;
  skos:prefLabel "Functional identifier"@en ;
  skos:definition ""@en .

Identification scheme

Definition:

An identification scheme provides a reference and scope for a set of identifiers.

OWL:

fnd:IdentificationScheme a owl:Class ;
  rdfs:subClassOf fnd:Scheme ;
  skos:prefLabel "Identification scheme"@en ;
  skos:definition "..."@en .

Identified thing

Definition:

A thing to which identifiers have been/may be attached.

OWL:

fnd:IdentifiedThing a owl:Class ;
  rdfs:subClassOf fnd:Thing ;
  skos:prefLabel "Identified thing"@en ;
  skos:definition "..."@en .

Identifier

Definition:

TBD

OWL:

fnd:Identifier a owl:Class ;
  rdfs:subClassOf fnd:Reference ;
  skos:prefLabel "Identifier"@en ;
  skos:definition ""@en .

Scheme

Definition:

A scheme is an agreement to use a common format, a common style or namespace.

Examples:

  1. The GS1 Global Trade Identification Number (GTIN).
  2. The International Standard Book Number (ISBN).

OWL:

fnd:Scheme a owl:Class ;
  rdfs:subClassOf fnd:Agreement ;
  skos:prefLabel "Scheme"@en ;
  skos:definition "..."@en ;
  skos:example "..." .

Properties

Identity Aspect Properties

IdentitAspect Properties

authority

Definition:

Denotes that one party in the scheme's agreement with responsibility for management of the scheme; for example, setting rules and arbitrating issues.

Example:

  1. The GTIN scheme has the organization GS1 as it's authority.
    gtin: :authority gs1: .

OWL:

fnd:authority a owl:ObjectProperty ;
  rdfs:subPropertyOf fnd:includesParty ;
  owl:inverseOf fnd:authorityForScheme ;
  rdfs:domain fnd:Scheme ;
  rdfs:range fnd:Party ;
  skos:prefLabel "authority"@en ;
  skos:definition "..."@en ;
  skos:example "..."@en .

authority for scheme

Definition:

Denotes a scheme which this party has authority over.

Example:

  1. GS1 is the authority for the GTIN scheme.
    gs1: :authorityForScheme gtin: .

OWL:

fnd:authorityForScheme a owl:ObjectProperty ;
  rdfs:subPropertyOf fnd:aPartyTo ;
  owl:inverseOf fnd:authority ;
  rdfs:domain fnd:Party ;
  rdfs:range fnd:Scheme ;
  skos:prefLabel "authority for scheme"@en ;
  skos:definition ""@en ;
  skos:example "..."@en .

broader classifier

Definition:

TBD

Example:

  1. Toy is a broader classifier than building bricks.

  2. Furniture is a broader classifier than chairs.
    ex:Furniture :broaderClassifier :Chairs .
  3. Science and Technology is a is a broader classifier than Computer Science.
    ex:ScienceAndTechnology :broaderClassifier ex:ComputerScience .

OWL:

fnd:broaderClassifier a owl:ObjectProperty ;
  owl:inverseOf fnd:narrowerClassifier ;
  rdfs:domain fnd:Classifier ;
  rdfs:range fnd:Classifier ;
  skos:prefLabel "broader classifier"@en ;

  skos:example "..."@en .
