The following proposal for additions to SKOS Core to support subject-based
indexing has been actioned:

Add the following properties to SKOS Core:

 - subject
 - isSubjectOf
 - primarySubject
 - isPrimarySubjectOf

Additionally, the following points are a part of this proposal:

(1) skos:subject is a sub-property of dc:subject.

(2) skos:subject and skos:isSubjectOf are inverse.

(3) skos:primarySubject is a sub-property of skos:subject.

(4) skos:primarySubject and skos:isPrimarySubjectOf are inverse.

(5) Wrt skos:subject, the following rule applies:

(?d skos:subject ?x)(?x skos:broader ?y)
(?d skos:subject ?y)

See the SKOS Core Vocabulary Specification for an overview of these terms:


All new terms have an 'unstable' status and comments and suggestions are
most welcome.
