Howard, collections in RDFCore are quite straightforward as you can see in http://www.w3.org/TR/2004/REC-rdf-mt-20040210/#collections and :C owl:oneOf (:a :b). is a shorthand for the triples :C owl:oneOf _:L. _:L rdf:type rdf:List. _:L rdf:first :a. _:L rdf:rest _:M. _:M rdf:type rdf:List. _:M rdf:first :b. _:M rdf:rest rdf:nil. -- Jos De Roo, AGFA http://www.agfa.com/w3c/jdroo/
