Yes, but there's a snag; as RDF work only on the URI resource level
(no added semantics to the typification of the URI resource) if
someone does an owl:sameAs between an identifier of a thing and a
locator of a thing (a locator being the resource itself as opposed to
being an identifier; example are you talking about Sun Corp
(http://sun.com/) or are you talking about their website
(http://sun.com/)) you can get a nasty case of integrity rot, and I've
not seen any proposals to address this issue (the RDF world is
essentially assuming modeling from the viewpoint of everything being
true).
I guess Mike don't like RDF *nor* Topic Maps now. :)
