I haven't followed all the discussion about dataset normalization, and I 
don't know the algorithm, but toward the end of today's call, it sounded 
like the best option may be something like Create A New URI Scheme.

I do have some experience trying to do that at the IETF, and I found it 
quite slow and difficult.   They wanted to understand why I wanted it, 
and they were not sympathetic to arguments that involved RDF.  Things 
may have changed, but you might want to consider some easier options 
that might work just as well:

- use an existing URI schema with a fixed prefix, like:

    http://www.w3.org/2013/dataset-id/

or

    tag:w3.org,2000:graph:

For these, you only need the consent of the domain holder, which should 
be easy enough.

- use a .well-known prefix, and somehow make the domain name not 
matter.  I'm not quite sure if this would work for your application.   
For these, you only need a stable spec, such as a WG Note or W3C Submission.

It may be that RDF's skolem constants (a variant on the second option 
above) will do.  See 
https://dvcs.w3.org/hg/rdf/raw-file/default/rdf-concepts/index.html#section-skolemization

I hope that helps.
