I, for one, knew that the AOI was working on a controlled vocabulary,
but their agenda was always geared towards describing press-images
rather than defining a general-purpose UCD-like proto-ontology.
However, their approach is at least systematic, which isn't always
true for what we've been discussing: both UCD's and the proposed
standard vocabulary/VOConcepts tend to look like random collection of
ideas which someday may be organized into an ontology. Yes, I know:
it's easy for AOI to be systematic when they limit their scope from
the beginning (e.g. they don't have words for things which aren't
easily shown in press-images).
The bottom line is that, yes, it would make sense to bring all of the vocabulary people together and to see if we can agree on a common basis. My guess is that there's little chance, so Rob's idea of everyone having their own private vocabularies (e.g. VOEvent's "GRB" versus the UCD-like "process.burst;em.gamma" versus nothing yet for the AOI list) and the IVOA providing the standard vocabulary as the means of constructing conversion tables still sounds like the best path: everyone gets what they want and the IVOA gets a common standard which everyone can live with. For example, adding standard vocabulary to the AOI list as a further column would be trivia and any missing elements would be a good sign of where the proposed standard vocabulary needs some additions.
