This is what I understand.

A URI is a string that relates to a thing/resource in the web, let's 
call this relationship "identifies".

If this thing/resource can return a REST:representation (i.e., a bunch 
of bits + some meta tags), then let's call it information resource 
(IR).  (In my opinion, the criteria for defining what is an IR and what 
is not is subjective. It is up to the resource owner to decide.)

An IR, therefore, is the union of all representations in all possible 
mime-type.  Of course, you can have an IR that has only a few mime-type 
representation. But unless the owner explicitly assert that, an agent 
cannot assume it by repeated tries.
