You can. Use URIQA to obtain the authoritative description
and see if the resource in question is rdf:type webarch:WebResource.

If it is, its URI should be resolvable to a representation.

If it isn't so specified, you can't be sure.

Hmmm... if the principle of URI opaqueness is to be
taken seriously, then while there are different URI schemes,
there are no URI categories visible to semantic web
applications.

If the systems in question are the Web and the Semantic Web,
then there would be interoperability, individual servers
being seen as subcomponents of those larger systems, not
systems in isolation.
