  Interoperability creates its own additional imperatives, yes.  I am
convinced that **accurate** interoperability (getting the same
inferences from the same data) requires use of a common foundation
ontology - and the 'foundation ontology' is only the set of ontology
elements (types, relations, axioms) required to permit the needed
specification of the meanings of the domain elements that people will
wish to formalize, in FOL at a minimum.  I call that the 'Conceptual
Defining Vocabulary".  I don't know what size foundation ontology will
be necessary and sufficient, but suspect that it will be in the
5000-10000 concept range.  I'm trying some experiments to discover what
that will be.  I think that such a foundation ontology is unlikely to
be adopted widely until someone with a compelling application makes
their foundation ontology available, in a form that's easier to learn
than Cyc or the Java programming language.  Or alternatively, some
funding agency actually funds the development of such an ontology by a
large collaborative effort, with interfaces and applications ($10-20
million over 2-3 years I expect).  I suspect that many of us may be
sufficiently exhausted by the debates to be ready for that.    (02)

[PC] Does anyone think we need a "Institute of Ontological Engineering"
that awards licenses after a qualifying exam??  Should we conjure up
such an exam?  Perhaps we can have grades: apprentice, journeyman,
Master?    (04)

More immediately, would it be possible to have a reviewed journal of
ontological engineering that is freely available on the internet?   . .
. So we can accelerate the process of coalescing as a scientific
discipline?  I can't afford the existing print journals.    (05)
