Re: what should the result of query be (and look like)

Sorry, but I think you're talking about some orthogonal issues about
the format of the query answer, and whether the answer to a query is
the matching triples themselves (which I was assuming for simplicity
in my example) or some binding information.  I was trying to clarify a
different point about whether certain KB triples (ones with
existential variables in them) are even considered to be matchable.
(Richard seemed to be saying they should not be; I apologize if I've
misunderstood his position.)

Your use of _:b in the results shows you think it's okay to return
existential variables.
