Thanks for doing this excellent summary.

Re. the above, a recent msg from Patrick Stickler at Nokia may be 
relevant. He is addressing the topic of 'named graphs' in a 
discussion of whether a blank node could be used as a name (no); but 
I want to draw your attention to the attitude expressed towards URIs 
and naming versus dereference.  (Patrick, forgive me for forwarding 
this without permission.)

.......I wanted to
offer one additional comment...

Even if a URI is required as a graph name, it need not involve
any significant mental or management effort to decide what URI
to use, if either (a) one does not care if the URI is human
readable (mnemmonic) and/or (b) one does not care if the URI
is dereferencable (though I think folks should).

E.g. one can simply employ UUIDs either in an http: URI

    http://example.com/id/dae07413-018c-43dc-9a0e-503a46484585

or in a uuid: or guid: URI

    uuid:dae07413-018c-43dc-9a0e-503a46484585
    guid:dae07413-018c-43dc-9a0e-503a46484585

or in a urn:uuid: URN

    urn:uuid:dae07413-018c-43dc-9a0e-503a46484585

etc. etc.

Thus, folks who tend to get their undies in a wad about having to
use http: URIs for stuff they don't consider "web accessible" or
folks who suffer angst about the linguistic baggage potentially
carried by a human readable URIs can relax (a bit).
