The RDF core specifications don't provide any mechanism to make such a claim. However you can use schema vocabularies such as DAML+OIL (see http://www.daml.org/) to make more precise descriptions of RDF ontologies. Without looking I'm not sure quite what DAML+OIL offers you in this particular case -- it has mechanisms like 'disjointWith' that may be of some use. Dan
