What does the "_" mean in your example?
It's a bNode (but one with a local name so you can reference it in multiple places. Could equally well have been:
[] a owl:Ontology ; owl:imports <http://example.org/namingOntology> . :JohnDoe a owl:NamedIndividual . Dave
Dave Lebling -----Original Message----- From: Joshua TAYLOR [mailto:[email protected]] ... If you don't have those declarations in ontology, then you'll need to import some ontology that does. E.g., _:ont a owl:Ontology . _:ont owl:imports <http://example.org/namingOntology> . :JohnDoe a owl:NamedIndividual . # if namingOntology declares :JohnDoe, you won't need this triple here :JohnDoe :hasName "John Doe" . So yes, in general, if you've got an ontology O that declares some vocabulary, then a dataset that's based on that vocabulary should import O.
