This section last edited on DateTime() is part of the ["SKOS/Reference"] wiki draft.
Section: Conceptual Resources
This section defines the vocabulary and formal semantics for the notion of a SKOS Conceptual Resource.
The notion of a SKOS Conceptual Resource is defined informally in the [http://@@TODO SKOS Primer].
skos:Concept has type Class.
The following graph is Consistent.
ex:foo rdf:type skos:Concept .
Except for the semantic condition given above, the formal semantics of skos:Concept are undefined.
The decision to leave the formal semantics of skos:Concept undefined has been made to allow different design patterns for using SKOS in combination with more formal languages such as OWL to be explored.
For example, interpreting skos:Concept and owl:Class as disjoint classes would be consistent with the semantics of SKOS. Alternatively, interpreting skos:Concept as a super-class of owl:Class would also be consistent with the semantics of SKOS.
See [http://@@TODO @@TODO section on SKOS + OWL patterns] for recommended design patterns for using SKOS in combination with OWL.
