The document that defines the legal vocabulary of OWL and the relationships between the concepts is the OWL semantics document not owl.owl, unless I am seriously confused as to how OWL is specified. Similarly, I don't think that the equivalent documents for RDF or RDFS define the vocabulary for these formalisms. In fact, these three documents are the wrong sort of documents to define a vocabulary, which is generally done by a DTD or XML Schema. Peter F. Patel-Schneider Bell Labs Research Lucent Technologies
