Thanks, all, for the help and clarifications. I've got another issue with getNameSpace() and I figured I'd ask it here, as opposed to starting another thread.
Once again, I'm using SUMO ( http://www.ontologyportal.org/SUMO.owl# ) as my test case. As was pointed out in answering my last question, this serialization has known problems, and I'm ready and willing to believe that SUMO is once again doing something wrong here. Anyway, on to the question. SUMO.owl defines a class : <owl:Class rdf:about="TheaterProfession"> <rdfs:isDefinedBy rdf:resource="http://www.ontologyportal.org/SUMO.owl"/> ... </owl:Class> I have an OntClass instance for this class (TheaterProfession). When I call .getNameSpace() on that object, I get " http://www.ontologyportal.org/TheaterProfession";. I think I *should* get " http://www.ontologyportal.org/SUMO.owl#TheaterProfession";. The default namespace for the ontology is defined as : <rdf:RDF xmlns="http://www.ontologyportal.org/SUMO.owl#"; Adding xml:base="http://www.ontologyportal.org/SUMO.owl#"; has no effect. Any help is greatly appreciated. Thanks, Kevin
