IANARE (I Am Not A RDF Expert), but I thought the question "What does
URI X correspond to?" was answered by the "rdf:type" associations, i.e.
the "class" of URI is metadata about the URI. And those types are for
many common things quite well defined. In other words, the URI does not
contain type information since that is handled by the metadata. Or am I
missing something?

Also, IAAAE (I Am An AOP Expert), and in that world (which seems to
correspond quite well with the RDF mindset) it is utterly and completely
uninteresting what "class" or id a particular object has, in terms of
determining what one can do with it. Instead one focuses entirely on the
set of interfaces that are exposed by the aspects attached to it.
