I didn't mean to imply that resources which have URIs aren't interesting
(though I practically said that). I meant to reinforce the idea that targets
of sentences are resources just as are resources directly identified by a
URI. By "interesting resources" I mean  people, places and physical objects.
Such resources *might* be directly identified by a URI, but just as well
might be indirectly identified as the target of a sentence or a formula (as
you very well point out).

What makes such indirectly identified resources so interesting to me is that
they include anything that does not yet have a name as well as things that
have natural language names (but not *yet* URIs). The resources that we
already identify with URIs are already on the web -- by considering
resources that don't (yet) have URIs we have a much larger semantic web.

Concerning [metaDataInURI-31] I'm not conviced that there is any pressing
need to treat URIs as other than opaque (aside from the resolution process).
If we are going to assign meaning to URIs based upon part of their syntax
such as their scheme (which also falls into issue [httpRange-14]) I think
this would work only if we changed specs like XML Namespaces, to require
that namespace names have a trailing '#' if they use the "http:" scheme etc.
On the whole there'd be too much retrofitting of the current web, XML
applications, etc. to make it practical?
