surely there is some world view, that given <x> and <y>, unless you 
know, infer, or are told otherwise, then they refer to different things? 
or is the view that given any two URIs it is default to consider them as 
all referring to the same thing?

take for example the case in question:

by looking only at the set of representations only, you'd conclude that 
they are all the same (?), by looking at the URIs only, you'd conclude 
that they are different (?)

what's your view on this case, how do you think/feel it should be
