Hmm, I think this paragraph goes too far ...

No?  Why not?  It seems to me that it does.

I think it's representing, not identifying.  If it were an
identifier, it should be a URI (or an EPR, I suppose 8-).

and redirects are representations 8-).

I think that Patrick has convinced me that "information resource" is
a cop-out.  *sigh*
