(2) yes, Cyc does not have mappings to the all (or any?) of the non-Cyc
ontologies that would be used to create the FO, and cannot currently serve
as a utility for translation among those ontologies. (02)

(3) Sure, but in order to do that and get it widely accepted, it would still
have to be worked on by a large coalition, with the same cost. I am
assuming that the FO project would use as much of the OpenCyc as is freely
available for use and relevant to the basic primitive concepts. If Cyc does
not release any more of its system for free public use, the cost will not
change. (03)

(4) The technical modifications to create a representation of primitives
based on the Longman vocabulary would cost a lot less, but that would not
solve the problem of getting other groups to use the Cyc. I believe that
in the first instance we do need to accommodate all logically consistent
approaches to the FO, so as to create a large community of users. The cost
is primarily to allow participation of such a large group, and to build the
translation axioms, though there will be parts such as work on the reasoner,
the subontology extractor, and the NL interface that will be expensive
beyond just the development of the FO. (04)
