I turned away from watching the DAWG language only for a short while.  
It seems to have moved
on the bnode issue rather quickly:

I'm not sure what it means to have the identity of a bnode extend beyond 
the graph it belongs to,
so I'd like this clarified.  In general, my assumption has always been 
that the identity of a bnode
has no meaning outside of the graph its in.  If you want it to have one, 
use a regular node.

Cheers, Bob
