You can use an rdf:resource to identify anything - it is not a URI that  
you necessarily expect to download, but it is an identifier. Which means  
you can use it for a person (some people have an rdf identifier or two  
already), a webpage (either "whatever you get at http://foo or an  
identifier that points to some RDF which describes a page) or a book  
(again, many of these have a URI as identifier from some other RDF). In  
other words by doing the standard thing that RDF always does, we have all  
the flexibility to cover whatever we want.

uri:uri is only useful for things that are actually available on the web.  
Restricting ourselves in that way, by usng something that isn't generic  
RDF, seems like a very bad idea to me.
