I guess I misunderstood, too. I thought
you were looking for the right way to do it
MKR is not triple-based, To keep things
simple, let's just call it quad-based.
You are looking at both the external and the
internal representation. MKR's context is
at space=s, time=t, view=v { ... };
Everything is stored by view. Space & time are
recorded, and in effect are subcontexts of view.

Hi Richard,
I see the query, but that doesn't give me any clue as to
how you might represent things internally. I guess I
misstated my question -- I'm interested in both the query
AND how it accesses temporal facts within an
established RDF-compliant tool. Is it simple to describe
what the internal expansion of your query looks like
(i.e., revealing your secret for overcoming the limitations of a
triple representation)?
Cheers, Bob
