Using b-nodes? So we can refer the html representation of 
http://example.com/abook as
_:abook a HtmlRepresentation;
             repOf <http://example.com/abook>.
Just like in human language, we talk about it as the "html 
representation" of <http://example.com/abook>. Right?

A representation is bound with its master URI, so we cannot talk about 
it without its master URI.

I snip the rest.  I don't think we differ too much but only on probably 
this one question.

Is there any distinguishable difference between a "document 
(awww:InformationResource)" and a person?

Current, AWWW thinks so (from my understanding).  I think not, which I  
just responded to Noah's question.

Hence, I propose to use "information resource" for *representations* 
because it feels - at least to me - natural to think that  in the web we 
work with "information resource" to understand things in the world.  A 
"document" located somewhere in the network, therefore, is not an 
information resource.  It is just an ordinary *thing* in the world, like 
a book, a person, etc...
