+1 . A very important point.

I would simply add (for sake of ultra qualification), use the RDF 
documents URL as its URI.
Use hash URIs to denote the subjects described by the RDF document. Most 
of the time "#{your-preferred-local-identifier}" tacked on to the RDF 
documents URL will suffice.

And a little addition to all of this, add triples that associate 
subjects with their host RDF document. Predicates that are useful in 
this context include: foaf:primaryTopic, foaf:topic, and wdrs:describedby .

Follow these guidelines and your RDF resources will be follow-your-nose 
friendly etc..
