This document describes the schema available from the SKOS namespace. The document is still under development and content may be subject to change.
The Simple Knowledge Organization System (SKOS) is a common data model for sharing and linking knowledge organization systems via the Semantic Web.This document provides a brief description of the SKOS RDF Schema.
For detailed information about the SKOS Recommendation, please consult the SKOS Reference [SKOS-REFERENCE] or the SKOS Primer [SKOS-PRIMER].
The SKOS data model expressed as RDF triples (in so far as possible) is given in the following resource:
This RDF schema defines an OWL ontology [OWL-REFERENCE]. SKOS vocabularies can then
be defined as instances of this ontology. Note that as the schema violates
some of the constraints on OWL DL ontologies, this ontology is an OWL Full
Ontology [OWL-SEMANTICS]. In
particular, some documentation properties are defined as
owl:ObjectProperty
and then used with data values. SKOS
documentation properties are defined as instances of
owl:ObjectProperty
and are then used to state properties of
classes within the SKOS vocabulary. Both of these situations violate the
requirement that the namespaces of classes, properties and individuals are
kept separated in OWL DL ontologies.
The following table gives an overview of the SKOS vocabulary. Note that this table can also be found in the SKOS Reference [SKOS-REFERENCE].
