True.  But my  point was the other way around.  I'm trying to make the point
that, as I understand it, RDF and SW don't require any of that HTTP semantics 
to be applied on top of the UUID.  I want a connection to the web.  Were there 
not the promise of a real, deep connection to the web, I might be tempted to 
use an existing logical formalism.

I would love to see the semantic web emerge organically in an exotically 
beautiful fractal pattern out of the existing web - as though it had always 
been there and is now just being revealed by RDF and OWL.

I know the pre-semantic web works.  And I think RDF and OWL will work.

But what I just can't yet see the logical connection that UUID-URIs in the 
semantic web have to HTTP-URIs in the pre-semantic web.  To me there is a 
wonderful, evocative, and metaphorical connection to HTTP-URIs that motivates 
me to want to continue the search for a stronger connection.

The difficulty I am having, is for me the pre-semantic web is more of a system that 
does things than a language that says something.  I want a logical system to make 
assertions with that has the ubiquity, reach, and power of the web.

I want both.  And I want the connection to be necessary and essential.
