Open Geospatial Consortium 2012-04-30 An RDF/OWL vocabulary for representing spatial information OGC GeoSPARQL – A Geographic Query Language for RDF Data OGC 11-052r5 Dave Beckett Nikki Rogers Participants in W3C's Semantic Web Deployment Working Group. Alistair Miles Sean Bechhofer An RDF vocabulary for describing the basic structure and content of concept schemes such as thesauri, classification schemes, subject heading lists, taxonomies, 'folksonomies', other types of controlled vocabulary, and also concept schemes embedded in glossaries and terminologies. SKOS Vocabulary OGC GeoSPARQL 1.0 The guidelines for using names of persons or organizations as creators also apply to contributors. Typically, the name of a Contributor should be used to indicate the entity. 1999-07-02 An entity responsible for making contributions to the resource. Contributor A [second property](/specifications/dublin-core/dcmi-terms/#http://purl.org/dc/terms/contributor) with the same name as this property has been declared in the [dcterms: namespace](http://purl.org/dc/terms/). See the Introduction to the document [DCMI Metadata Terms](/specifications/dublin-core/dcmi-terms/) for an explanation. Examples of a Creator include a person, an organization, or a service. Typically, the name of a Creator should be used to indicate the entity. 1999-07-02 An entity primarily responsible for making the resource. Creator A [second property](/specifications/dublin-core/dcmi-terms/#http://purl.org/dc/terms/creator) with the same name as this property has been declared in the [dcterms: namespace](http://purl.org/dc/terms/). See the Introduction to the document [DCMI Metadata Terms](/specifications/dublin-core/dcmi-terms/) for an explanation. Date may be used to express temporal information at any level of granularity. Recommended practice is to express the date, date/time, or period of time according to ISO 8601-1 [[ISO 8601-1](https://www.iso.org/iso-8601-date-and-time-format.html)] or a published profile of the ISO standard, such as the W3C Note on Date and Time Formats [[W3CDTF](https://www.w3.org/TR/NOTE-datetime)] or the Extended Date/Time Format Specification [[EDTF](http://www.loc.gov/standards/datetime/)]. If the full date is unknown, month and year (YYYY-MM) or just year (YYYY) may be used. Date ranges may be specified using ISO 8601 period of time specification in which start and end dates are separated by a '/' (slash) character. Either the start or end date may be missing. 1999-07-02 A point or period of time associated with an event in the lifecycle of the resource. Date A [second property](/specifications/dublin-core/dcmi-terms/#http://purl.org/dc/terms/date) with the same name as this property has been declared in the [dcterms: namespace](http://purl.org/dc/terms/). See the Introduction to the document [DCMI Metadata Terms](/specifications/dublin-core/dcmi-terms/) for an explanation. Description may include but is not limited to: an abstract, a table of contents, a graphical representation, or a free-text account of the resource. 1999-07-02 An account of the resource. Description A [second property](/specifications/dublin-core/dcmi-terms/#http://purl.org/dc/terms/description) with the same name as this property has been declared in the [dcterms: namespace](http://purl.org/dc/terms/). See the Introduction to the document [DCMI Metadata Terms](/specifications/dublin-core/dcmi-terms/) for an explanation. The described resource may be derived from the related resource in whole or in part. Recommended best practice is to identify the related resource by means of a string conforming to a formal identification system. 1999-07-02 A related resource from which the described resource is derived. Source A [second property](/specifications/dublin-core/dcmi-terms/#http://purl.org/dc/terms/source) with the same name as this property has been declared in the [dcterms: namespace](http://purl.org/dc/terms/). See the Introduction to the document [DCMI Metadata Terms](/specifications/dublin-core/dcmi-terms/) for an explanation. The range of skos:altLabel is the class of RDF plain literals. skos:prefLabel, skos:altLabel and skos:hiddenLabel are pairwise disjoint properties. alternative label An alternative lexical label for a resource. 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 A note about a modification to a concept. definition A statement or formal explanation of the meaning of a concept. editorial note A note for an editor, translator or maintainer of the vocabulary. example An example of the use of a concept. The range of skos:hiddenLabel is the class of RDF plain literals. skos:prefLabel, skos:altLabel and skos:hiddenLabel are pairwise disjoint properties. hidden label 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 A note about the past state/use/meaning of a concept. note A general note, for any purpose. This property may be used directly, or as a super-property for more specific note types. 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. The range of skos:prefLabel is the class of RDF plain literals. skos:prefLabel, skos:altLabel and skos:hiddenLabel are pairwise disjoint properties. preferred label The preferred lexical label for a resource, in a given language. scope note A note that helps to clarify the meaning and/or the use of a concept.

Broader concepts are typically rendered as parents in a concept hierarchy (tree). has broader Relates a concept to a concept that is more general in meaning. By convention, skos:broader is only used to assert an immediate (i.e. direct) hierarchical link between two conceptual resources. has broader transitive skos:broaderTransitive is a transitive superproperty of skos:broader. 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 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. skos:exactMatch is disjoint with each of the properties skos:broadMatch and skos:relatedMatch. has exact match 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 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 Relates a resource (for example a concept) to a concept scheme in which it is included. A concept may be a member of more than one concept scheme. 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. is in mapping relation with Relates two concepts coming, by convention, from different schemes, and that have comparable meanings has member Relates a collection to one of its members. 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. has member list Relates an ordered collection to the RDF list containing its members. has narrower match skos:narrowMatch is used to state a hierarchical mapping link between two conceptual resources in different concept schemes. Narrower concepts are typically rendered as children in a concept hierarchy (tree). has narrower Relates a concept to a concept that is more specific in meaning. By convention, skos:broader is only used to assert an immediate (i.e. direct) hierarchical link between two conceptual resources. has narrower transitive skos:narrowerTransitive is a transitive superproperty of skos:narrower. 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. skos:related is disjoint with skos:broaderTransitive has related Relates a concept to a concept with which there is an associative semantic relationship. has related match skos:relatedMatch is used to state an associative mapping link between two conceptual resources in different concept schemes. is in semantic relation with Links a concept to a concept related by meaning. This property should not be used directly, but as a super-property for all properties denoting a relationship of meaning between concepts. is top concept in scheme Relates a concept to the concept scheme that it is a top level concept of.
