The specs like GRDDL, RDFa etc. are designed to provide the RDF 
representation of some information resource.  So, it saves authors from 
generating RDF documents for their respective HTML/XML pages that are 
already there.  But to use this as a general bridge to any resource or 
as a substitute for content negotiation, IMHO, missed the point.

For instance, the descriptions of two different proteins can be merged 
in one HTML/RDF document.  Then if another party wants to make 
assertions about one of the "proteins" in question, how can you do that 
unambiguously without giving each protein a URI?
