Well, just about anywhere, at least in the general case.  For example,
suppose that the class is rdfs:Class.  Information about rdfs:Class can be
found in just about any RDF document.

Of course, there are very many cases where a lot of information about a
class (or any other property) should be found (maybe not now, but when the
Semantic Web actually gets going) by dereferencing a URI related to the URI
references of the class.  Of course, this would only be one organization's
information about the class, and other agents might reasonably have
different views.
