Last corrections implemented, as listed below.
By and large a simple exercise, particularly since many already exist, but one sees how this process has to asymptotically converge BY DEFINITION, not by time or effort. May I suggest that the state of the Vocabulary/Thesaurus be fixed by the end of this week - last chance for last-minute additions! Whatever you can't find after that must not have been very important.
Can we find appropriate mathematical, physical and/or chemical vocabularies out there? We could unload a lot of baggage.... In the long term, surely there will be available vocabularies for the semantic web - everyone can't be expected to re-invent the circle or the logarithm. On the other hand, we don't want to use a vocabulary from www.viagra.tv - doesn't the IVOA maintain any contacts to some international Math/Physics/Chemistry/.... organizations? Isn't there an International Virtual Mathematics Chalkboard Association? or an International Virtual Testtube Association?
Rob's suggestion of splitting things into the original thesaurus (or at least a corrected version of the old thesaurus - mixed cases, underbars, and lots of tokens shifted into ALTs) and new additions would be a pain, given the amount of cleaning up we've done, but if ya'll want it that way and as long as it means that the WG makes a decision about how to handle multiple vocabularies: ivorn formats, normative file formats, suggested translation infrastructure (e.g. references to math:ellipses). If this will take too long, I vote for one giant starting vocabulary based upon the IAU but with all the present corrections/additions.
Wait a minute - a great idea: wouldn't the IAU/IVOA thesaurus be a GREAT place to put all the STC shortcuts?! How else are we to know where to find them? Or create a STC shortcut vocabulary as a new, practical, and exemplary example.

Ooops - as an old CV person, I should have thought of

I agree with Rob that this could be done ontologically differently if we knew how to combine tokens, but these are very common phrases in the binary business, so
"primary_stars" BT "companion_stars" "secondary_stars" BT "companion_stars" "tertiary_stars" BT "companion_stars""elliptical_galaxies"

Separate vocabulary is probably a good idea - aren't there any math ones out there? This is a good example of where we might be able to be conformal to an external semantic-web namespace if it exists.

Chemistry vocabularies/ontologies, anyone?

Ugh. Might be more elegant, but since they're already in the IAU thesaurus and VERY astronomical, we should leave them in.
