I guessed as much :-) I was just interested.

Sure. I didn't mean to suggest it wasn't useful - you want something
to reason /about/, otherwise life becomes rather dull. I guess my
question is: is the rdf rule WG going to produce simply a means to
express rules, or something more like a rules programming language (a
la prolog, N3)?

OTOH I can see the need in the proof/justifcation language (perhaps
'diagnostic' since the former terms are so fraught with controversy).
