label: DCMI Type Vocabulary

alternative label
type: AnnotationProperty
comment: The range of skos:altLabel is the class of RDF plain literals.
comment: skos:prefLabel, skos:altLabel and skos:hiddenLabel are pairwise disjoint properties.
definition: An alternative lexical label for a resource.
example: Acronyms, abbreviations, spelling variants, and irregular plural/singular forms may be included among the alternative labels for a concept. Mis-spelled terms are normally included as hidden labels (see skos:hiddenLabel).

change note
type: AnnotationProperty
definition: A note about a modification to a concept.

definition
type: AnnotationProperty
definition: A statement or formal explanation of the meaning of a concept.

editorial note
type: AnnotationProperty
definition: A note for an editor, translator or maintainer of the vocabulary.

example
type: AnnotationProperty
definition: An example of the use of a concept.

hidden label
type: AnnotationProperty
comment: The range of skos:hiddenLabel is the class of RDF plain literals.
comment: skos:prefLabel, skos:altLabel and skos:hiddenLabel are pairwise disjoint properties.
definition: A lexical label for a resource that should be hidden when generating visual displays of the resource, but should still be accessible to free text search operations.

history note
type: AnnotationProperty
definition: A note about the past state/use/meaning of a concept.

note
type: AnnotationProperty
definition: A general note, for any purpose.
scope note: This property may be used directly, or as a super-property for more specific note types.

preferred label
type: AnnotationProperty
comment: A resource has no more than one value of skos:prefLabel per language tag, and no more than one value of skos:prefLabel without language tag.
comment: The range of skos:prefLabel is the class of RDF plain literals.
comment: skos:prefLabel, skos:altLabel and skos:hiddenLabel are pairwise disjoint properties.
definition: The preferred lexical label for a resource, in a given language.

scope note
type: AnnotationProperty
definition: A note that helps to clarify the meaning and/or the use of a concept.

Member Of
type: ObjectProperty
range: Vocabulary Encoding Scheme
definition: A relationship between a resource and a vocabulary encoding scheme which indicates that the resource is a member of a set.

has broader match
type: ObjectProperty
sub property of: has broader
sub property of: is in mapping relation with
inverse of: has narrower match
definition: skos:broadMatch is used to state a hierarchical mapping link between two conceptual resources in different concept schemes.

has broader
type: ObjectProperty
sub property of: has broader transitive
inverse of: has narrower
comment: Broader concepts are typically rendered as parents in a concept hierarchy (tree).
definition: Relates a concept to a concept that is more general in meaning.
scope note: By convention, skos:broader is only used to assert an immediate (i.e. direct) hierarchical link between two conceptual resources.

has broader transitive
type: ObjectProperty
sub property of: is in semantic relation with
inverse of: has narrower transitive
type: TransitiveProperty
definition: skos:broaderTransitive is a transitive superproperty of skos:broader.
scope note: By convention, skos:broaderTransitive is not used to make assertions. Rather, the properties can be used to draw inferences about the transitive closure of the hierarchical relation, which is useful e.g. when implementing a simple query expansion algorithm in a search application.

has close match
type: ObjectProperty
sub property of: is in mapping relation with
type: SymmetricProperty
definition: skos:closeMatch is used to link two concepts that are sufficiently similar that they can be used interchangeably in some information retrieval applications. In order to avoid the possibility of "compound errors" when combining mappings across more than two concept schemes, skos:closeMatch is not declared to be a transitive property.

has exact match
type: ObjectProperty
sub property of: has close match
type: SymmetricProperty
type: TransitiveProperty
comment: skos:exactMatch is disjoint with each of the properties skos:broadMatch and skos:relatedMatch.
definition: skos:exactMatch is used to link two concepts, indicating a high degree of confidence that the concepts can be used interchangeably across a wide range of information retrieval applications. skos:exactMatch is a transitive property, and is a sub-property of skos:closeMatch.

has top concept
type: ObjectProperty
inverse of: is top concept in scheme
domain: Concept Scheme
range: Concept
definition: Relates, by convention, a concept scheme to a concept which is topmost in the broader/narrower concept hierarchies for that scheme, providing an entry point to these hierarchies.

is in scheme
type: ObjectProperty
range: Concept Scheme
definition: Relates a resource (for example a concept) to a concept scheme in which it is included.
scope note: A concept may be a member of more than one concept scheme.

is in mapping relation with
type: ObjectProperty
sub property of: is in semantic relation with
comment: These concept mapping relations mirror semantic relations, and the data model defined below is similar (with the exception of skos:exactMatch) to the data model defined for semantic relations. A distinct vocabulary is provided for concept mapping relations, to provide a convenient way to differentiate links within a concept scheme from links between concept schemes. However, this pattern of usage is not a formal requirement of the SKOS data model, and relies on informal definitions of best practice.
definition: Relates two concepts coming, by convention, from different schemes, and that have comparable meanings

has member
type: ObjectProperty
domain: Collection
range: Class
  union of: Collection
  union of: Concept
definition: Relates a collection to one of its members.

domain: Ordered Collection
comment: For any resource, every item in the list given as the value of the skos:memberList property is also a value of the skos:member property.
definition: Relates an ordered collection to the RDF list containing its members.

has narrower match
type: ObjectProperty
sub property of: is in mapping relation with
sub property of: has narrower
definition: skos:narrowMatch is used to state a hierarchical mapping link between two conceptual resources in different concept schemes.

has narrower
type: ObjectProperty
sub property of: has narrower transitive
comment: Narrower concepts are typically rendered as children in a concept hierarchy (tree).
definition: Relates a concept to a concept that is more specific in meaning.
scope note: By convention, skos:broader is only used to assert an immediate (i.e. direct) hierarchical link between two conceptual resources.

has narrower transitive
type: ObjectProperty
sub property of: is in semantic relation with
type: TransitiveProperty
definition: skos:narrowerTransitive is a transitive superproperty of skos:narrower.
scope note: By convention, skos:narrowerTransitive is not used to make assertions. Rather, the properties can be used to draw inferences about the transitive closure of the hierarchical relation, which is useful e.g. when implementing a simple query expansion algorithm in a search application.

has related
type: ObjectProperty
sub property of: is in semantic relation with
type: SymmetricProperty
comment: skos:related is disjoint with skos:broaderTransitive
definition: Relates a concept to a concept with which there is an associative semantic relationship.

has related match
type: ObjectProperty
sub property of: is in mapping relation with
sub property of: has related
type: SymmetricProperty
definition: skos:relatedMatch is used to state an associative mapping link between two conceptual resources in different concept schemes.

is in semantic relation with
type: ObjectProperty
domain: Concept
range: Concept

is top concept in scheme
type: ObjectProperty
sub property of: is in scheme
domain: Concept
range: Concept Scheme
definition: Relates a concept to the concept scheme that it is a top level concept of.
