I agree, but that need not stop us from sharing and combining
inference RESULTS of multipe knowledge bases, since the inferred results
can have a simpler ontology than their source knowledge bases.
My standard example is a result for a fixed time point (as `now') from
a knowledge base that had used time-oriented representations and reasoning.
(that is the essence of the mediator architecture, and also apllies to KQML)
