I agree with most of your response to my remark, with the exception
of one sentence.    (02)

The point that I very strongly disagree with is that "OWL is
the best technology available."  At VivoMind, we are delighted
when our competitors use OWL because we can translate their
sources to Prolog and get orders of magnitude improvement over
their "native" implementations.    (05)

But for heavy-duty lifting (gigabytes and terabytes) we would
never dream of using RDF or OWL.  Those languages are hopelessly
inadequate for truly massive volumes of data.  Just note that
Google doesn't use those languages.  They know better.    (06)
