That is the problem I try to solve with the mod_link spec for RSS 1.0.  
It is hard to use ad hoc URLs in a distributed system without knowing 
what the document represents.  There are of course hacks to this system 
but if you don't have the media relationships "this if a FOAF file in 
RDF and in English" then it becomes hard to determine if you should use 
the resource.
