Hi Rick,
I think there might be a slight problem with your script that generates the vocabularies. If you look at any relationship, you will find that it points to itself rather than another concept.
I have done a quick analysis of the IAU93 and IVOAT vocabularies.
Number of
IAU93 IVOAT Top level concepts
1720
1203

Narrower relationships

The original IAU thesaurus in SKOS format in a semi-final form along with the latest IVOAT and experimental math thesauri are available at the cleaned up site
http://www.astro.physik.uni-goettingen.de/~hessman/rdf/
Others are forthcoming. As each thesaurus is nominally OK'd by the semantics group (e.g. IAU93), they need to be moved to the IVOA.
Have we agreed on the TokenSyntaxMostLikelyToBeLeastDispleasingToTheLargestNumberOfSemanticsWorkingGroupMembers? If so, I believe the IAU93 thesaurus can be declared practically done. Check off item, move to next....

I might add that therefore limiting the effort to SKOSifying the IAU Thesaurus will bring the most rapid IAU recognition possible. In the mean time, there's no reason we can't use intermediate work products within the IVOA. - Rob
Indeed there's no reason why we can't have several thesauri up and running when we present the SKOS proposal to the IVOA and IAU. I believe that Rob is practically finished with the VOEvent thesaurus..... If IVOAT is preliminarily finished, then hopefully people will simply nod at the fact that IAU93 is formally expressed for compability and political purposes but not bother to use it (heaven forbid).
