Supporting such a model may become a real pain as mappings are not 
stable. I think standards like RDF should not get into this. If an 
application needs to be aware of the relationships between URIs as you 
have demonstrated, building such a mechanism (e.g. a set of properties 
in RDF) is easy. The difficult part is controlling the accuracy of those 
  mappings through time and change. Web application/server behavior is 
another factor, as a web server may serve different documents for the 
same URI depending on the client. How can you cover all the 
possibilities in a usefull way?

I think we need something bigger to place that upon. RDDL was a good 
start. Something that documents a resource, it's type, whether it's 
retreivable, static or dynamic, possible URI mappings or relationships 
and the conditions under which those mappings are valid etc. Loads and 
loads of work in this one.
