This added another new grammar term >http://www.ilrt.bris.ac.uk/discovery/2004/01/turtle/#integer My recollection is that the OWL cardinalities are expressed as xsd:nonNegativeInteger values. It's not clear to me that RDF has a way to allow xsd:integer values where these are required, though I think the other way would work through datatype subclass membership; e.g.: _:x a xsd:nonNegativeInteger . xsd:nonNegativeInteger rdfs:subClassOf xsd:integer . |- _:x a xsd:integer . But not the other way round. #g ------------ Graham Klyne For email: http://www.ninebynine.org/#ContactReceived on Friday, 26 March 2004 05:14:10 UTC
