Actually, thinking more about it now, the "name" example is, I think, an example of the kind of constraint that OWL/RDFS can't express (limits on container structure). If the example were Person/name/age then you could use OWL's cardinality mechanism. Ok, so maybe the fit isn't perfect, but it should work in many (most?) cases. > If you try to validate a specific profile of RDF/XML, you > could have similar problems. What's a "profile" of RDF/XML, and what kind of validation do you mean? Mark. -- Mark Baker. Ottawa, Ontario, CANADA. http://www.markbaker.ca
