Actually, I'm not sure I understand the question, but in fact, the DR is 
not involved at all in this use case. 

The DR has attribution and scope as well as the description itself. In 
this case, as well as other cases where you link from an HTML page, 
just the description is needed, the scope will be implicit (the 
description applies only to the resource that links to it) and it is 
assumed to be attributed to the creator of the resource. 

Phil has been kind enough to provide descriptions that can be used for 
this purpose, see
These descriptions could form the basis for a lot of average-user 
labelling. For example, Joe Random Blogger could add a link element to 
his blog saying something like
<link rel="POWDER-Description" 
and be sure that he has adequately labelled as a news site. For those 
who will not need the full power of creating DRs, labelling should be 
as simple as this. 

And for the RDF people, a couple of triples should suffice to do this 
too, that's what I'm getting at. Don't know if that answered your 
question, but I hope it clarified a bit.
