But what is the more general principle here? The document that Tim

distinctions among work/expresion/manifestation).

It then says:

"Each resource may have a URI. The authority which allocates the URI is 
the authority which determines wo what it refers: Therefore, that 
authority determines to what extent that resource is generic or 

I'm probably missing something, but it seems to me that this 
contradicts the notion that one cannot use a URI to refer to something 
which is not in fact the resolved document (the homepage in this case). 
"The Bible" seems entirely analogous to "M. David" the person in this 

To be really practical, what does this URI refer to?

or might it in fact name the book itself, with the web page merely 
being a representation of it?
