In the comment property defining Ontology, it states that an ontology is a document describing a vocabulary ... Is the ontology the document, or is the ontology an abstract entity, and the document one of many possible representations of it? One might wish to make statements about the abstract entity which are not true of the document and statements about a document which are not true of the abstract entity. These should therefore have different URI's. In the light of that, should the fomulaic: <Ontology about=""> have an absolute URI of the ontology between the "'s as the element is describing the ontology, not the document. [I am in general supportive of Sergey's stylistic suggestion that in general, URI's in about attribute values should be absolute - it is rather irritating to cut and paste a self contained chunk of RDF and find the semantics have changed. Also, if a mirror service stores an exact copy of an RDF document, to have the copy have different semantics to the original seems unhelpful.] There are a couple of minor nits in the example ontology: 1) Father is desribed as having range Man, but presumably inherits domain Animal from Parent. Mother is similar. 2) TallThing is omitted from the annotated version. Brian McBride HPLabs
