Fine, I understand. But then you can't "link" to a non-Web object.   
But I was chiefly commenting on DanB's historical recollections.

Ah no, what I was talking about there were just plain bugs and bad  
design decisions. But this is a more fundamental split, between RDF as  
a description format and RDF as a purely metadata tool intended to aid  
Web searching. Maybe these are compatible, but AFAIK the original,  
intended, design goal for RDF was the former.
