I though we all collectively accepted the norm Giovanni iterates above?

Of course you can save records (triples) in a Quad / Triple store with 
whatever URIs you choose, but at deployment time best you use URIs 
associated with your own Data Space and then owl:sameAs to the source. 
Basically, this is the pattern I wrote about when we started releasing 
DBpedia, NeuroCommons, Bio2Rdf, and MBZ to EC2. In all of these cases 
the de-referencable URIs exist in the instance owner's data space bound 
namespace thereby localizing the de-referencing tasks.

Yes, "Data Access by Reference" is about not having to interact with 
"Data by Value" which requires localization of data in order to actually 
use the values :-)
