Fine, I understand. But then you can't "link" to a non-Web object. But I was chiefly commenting on DanB's historical recollections. >> And that is why I designed the semantics based on a logical model >> theory rather than a computational annotation system.

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.
