   That looks like an excellent summary of a methodology to find
commonality among the existing UOs.
   I mentioned in a previous note that I though that it might be
helpful to focus initially on that part of existing UOs required to
formalize and relate several existing Knowledge Classifications such as
the UMLS-SN, FEA-RMO top level, and DoD Core Taxonomy top level.  Do
you view such a focus as consistent with the overall plan you describe?    (01)

I am separating out this part of the thread.
I apologize if some of this is obvious.  It is often "hard to 
understand what is understood".    (05)

This is a suggested plan of work for the upper ontology subgroup    (06)

1       Collect suggested upper ontologies    (07)

2       Compare and determine differences
2.1             In elements (presence / absence and, more difficult, 
2.2             in relationships    (08)

3       Try to resolve differences, creating a superstructure that
         the non-contradictory parts of various schemes
3.1             By adding elements
3.2             By adding relationships    (09)

4       Articulate the remaining differences so that they are clearly 
understood    (010)

In addition, the subgroup should deal with ontologies that can be 
reused in many contexts, such as an ontology of time concepts.    (011)

My reworking of the WordNet top level (attached) may be useful in this
context.    (012)
