I very strongly agree. (03)

Again, I agree with Pat Hayes. You should either do it yourself
or find success stories that have been achieved with Cyc, SUMO,
or other ontologies. (06)
If you can't find success stories with other upper ontologies
that have actually been implemented, nobody is going to believe
your claims about some nonexistent FO. (07)

Pat and I were involved with the Shared Reusable Knowledge Base
(SRKB) effort, the ontology group that met in Heidelberg, Germany,
the SUO, the ontolog forum, etc. Every one of those projects
strongly supports Pat's conclusions, which I strongly agree with. (09)

Since the FO doesn't exist, Pat C can claim wonders for it, but
the current evidence supports Pat H. (011)

Pat H did have a good proposal: (013)

That is very similar to the registry/repository approach that I
recommended. I also added the recommendation for metadata with
each ontology that would exhibit its relationships to other
ontologies in a generalization hierarchy. (015)
If it is possible to have a better FO than Cyc or OpenCyc,
a promising way to achieve it is through evolution by means
of many people working on the hierarchy. A major advantage
of such an approach is that we can start very quickly with
a registry hosted on Peter Yim's web site or the IEEE site.
In fact, OpenCyc and SUMO can be placed on that site, and
people can begin by "voting with their feet". (016)
The start-up cost is minimal, and we don't have to depend
on selling a multimillion dollar project to skeptical
agencies or investors. (017)
