The RDF Schema spec says that rdfs:member can be used between any resources to indicate that the object is a member of the subject. [1] The subject is not necessarily an RDF Container. However, Jena and ARQ have the default behavior of treating rdfs:member as a computed property. They compute it using the RDF Schema inference rule for the container membership properties, rdf:_1, rdfL_2, etc. Concrete rdfs:member triples are in fact ignored. This behavior can be disabled, but it is the default. [2] I'd appreciate hearing views on how rdfs:member should be used, and how it is being used in practice. Thx.
