I would be interested in an answer in this direction too.  I am guilty 
of diverting Michael's question off to a different one.  I think that I 
might have guessed too much on what the potential direction of his question.

Thinking of Michael's specific question -- i.e., the definition of two 
representations are equivalent, I am, in fact, not optimistic that there 
can or should be one such definition or recommendation. To use OO 
programming language as an example. Most of them have defined at least 
two kind of *equivalence*.  One is based on object identity and the 
other a user-implemented method, such as java's equals().  This is 
reasonable because had a language defined a fixed semantics of the 
second equivalence, it will definitely hurts its robustness as a general 
purpose programming language.  For me, I have always thought that URI is 
the interface to the Web and awww:representation the implementation. 
Hence, I don't expect that the outcome of a potential discussion will be 
anything concrete, if any.
