Yeah, I've thought about too, but not done anything. It would be nice to 
have.

My idea was to implement a system that would have only 303-URIs. 

The same handler (or whatever, mod_perl seems to be going out) would handle 
two servers, both e.g. http://id.example.org/dahut and 
http://rdf.example.org/dahut . The former would be the URI of the actual 
thing, the latter an information resource about it. The actual data would 
be in an RDF database.

If a client chooses to dereference http://id.example.org/dahut, the server 
would internally a do a DESCRIBE on the Request-URI and if it returns a 
result, cache the result, and respond with a 303 with 
Location: http://rdf.example.org/dahut which would return 200 with the 
already (mem)cached result. If the DESCRIBE returned no result, the server 
would return a 404.


Cheers,
