Yeah, unfortunately, we don't have much intersection here between people
who know/care about RIF and SPARQL.

Can someone here make the case for why RIF folks should care about this?
I tried to get interest from the RIF-WG, but I don't think I explained
it very well.

The general idea, I gather, is to be able to do SPARQL queries against a
RIF-powered deductive triple store.  But I don't understand what needs
to be spec'd for that; it seems to me like the parts fit together in
exactly one obvious way.  (RIF certainly anticipates this use case; we
have a Feature At Risk on 1-to-1 lists: rdf:Lists map to RIF lists, but
do they map back?  I hope so, but no one has implemented that yet.)
