Why does *RDF* need this? You seem to talk about a SPARQL store use case, so shouldn't it be in SPARQL?

So in SPARQL Update, in addition to the current ways of adding data:
 
  INSERT DATA { (RDF goes here) }

there could be an additional option:

  INSERT DATA AUTO_URI { (RDF goes here) }

And this makes the store mint unique URIs (be it tag: or bnode: or http: in a configurable space). I suppose a store could have a preference that makes AUTO_URI the default.

Best,
Richard
