I tend to think that:
Thing = what is referenced by a URI, let's labeled it like T(uri)
representation = what is returned when a URI is dereferenced, let's 
labeled it by R(uri).

The current problem is, if uri_1 = uri_2, then

T(uri_1) = T(uri_2) should always be true.

But, R(uri_1) = R(uri_2) is not necessarily true because it depends on 
HOW and WHEN the URI is dereferenced.

The ambiguity on the semantics of R(uri) causes many problem and needs 
to be clarified.
