I have been following the discussion and perhaps am being a bit harsh.
There are some very good and important points being raised and some of
them are no doubt important to advancing the field. (01)
I am a bit more oriented toward the practical side (perhaps I just don't
have anything to contribute to angel choreography). (02)
I am beginning to get the strong sense that there is no possibility of
one all-encompassing FO and that the best service to mankind, that I can
contribute to, is the provision of a place where ontologies can be
recorded and discussed. (03)
I hope that this will lead to multiple sets of ontologies that have been
reviewed and informally "certified" to be internally consistent at least
to the point where one can make assertions like: (04)
"If you take these 3 ontologies and use them together, there will not be
any internal inconsistencies that will make your project do stupid or
surprising things." or
"If you use Ontology A with Ontology B, you will have to adjust these 7
terms to make the ontologies consistent before you start to add your
"If you try to use Ontology X in North America, you will want to adjust
these 27 terms to align them with SOX terminology." (05)
I may be wrong but I think that this is one of the biggest problems
facing application developers. There are tons of ontologies but no place
that can tell you which ones will suit your needs or which ones are
designed to work together. (06)
I would suggest the wiki rather than some centrally controlled database
since I think that there are so many areas covered by ontologies, it
will be hard to put together a expert group that can decide what is true
and what is not true. A wiki allows the community to contribute and
evaluate the content. I think that it would be hard to get a consensus
about what group of people are responsible for all human knowledge.
It has worked fairly well for Wikipedia and in the end the error rate in
Wikipedia is pretty close to most major encyclopedias but the content
grow much faster. (07)
I would like the effort to be open source and have as wide a base of
contributors as possible.
Is there some other approach besides the wiki that is better?
Are the additional sections that the wiki should include?
Are any of the sections that I proposed silly or not required? (08)
Perhaps we can devote 2009 and 2010 to describing the repository
structure. Shall we switch the angels or change the pin dimensions? (09)

I think that there are many different things that people are trying to
do. Some of them are worthwhile as basic research but not as practical
advice for someone who needs a solution to an immediate problem.
There is no doubt that a cancer patient benefits from a lot of research
that was done in ivory towers but the effort spent in the training of
the attending medical team is also important.
I do not object to angel choreography in principle, but I do see that
there is a lot of very useful knowledge being discussed here that would
be helpful to people with real problems if we had a place to construct
it into actionable information. (010)
There is no shortage of ontologies at the moment. They are just too hard
to find and evaluate. (011)
