If that is the case, then app/rdf is fine. I don't entirely understand how
this works, but perhaps this is a consequence of layering  for Fast OWL as
well as Large OWL. When I asked for a 'better story' I am really asking for
the logic that gets me to the OWL model theory from app/rdf.

I guess that I just don't understand this (really). Does this have something
to do with LBase?

Perhaps, but I am not really pushing for app/owl as long as what you say
above holds (that there is a path from app/rdf to the OWL model theory). If
that path were well described then I would be totally happy with app/rdf --
perhaps I am just being dense.
