Dear John,
Summarising ten pages into few lines, we can say that, by comparing the
upper levels of OpenCyc, SUMO, DOLCE and the top-level of the CG
hierarchy, the formal and conceptual differences are so evident that
any form of "merging" is very difficult to envisage. You can add that
the top level of the 'static' ontology of concepts of NKRL is based on
the differentiation between 'sortal' and 'non-sortal' concepts -
'sortal' concepts can have direct instances, 'non-sortal' concepts,
like properties or substances, cannot have direct instances. This
introduces another one conceptual difference with respect to the
existing proposals, and we could of course continue. By the way, with
respect to NKRL, you know also that the 'really important' ontology in
this language/environment is not the usual, 'static' one ontology, but
the (new) ontology of complex events...
Anyway, the procedure you mention in your mail, which boils down to
submitting '... a letter ballot to approve a study period to determine
whether...' seems to be neatly wiser than that followed by the European
Commission on this side of the Ocean, and consisting in wasting the
money of the European taxpayers in launching questionable 14.7 million
Euro projects like NeON - see Azemat's remarks few days ago. And this
without taking into account the millions Euro already spent these past
years to finance a Semantic Web industry that does not start off.
You should, may be, buy my book...
Best regards,

GPZ> Another SUO, ten years later ...
Not quite. The SUO project had been approved by the IEEE as a
standards project. This is a letter ballot to approve a study
period to determine whether they should have a standards project.
They can apply all the experience gained from the SUO to this
study project.

Could you summarize that point?
