Indeed. Of course, we've told Rick this several times over the past
couple of years in the VOEvent group. Perhaps one of his concept
list dohickeys will stick one of these days :-)

Who is "we"? Has there been some official policy promulgated that
the Virtual Observatory shall produce no facilities useful for
historical purposes? Indeed unlikely to be useful for VOEvent, but
perhaps RTML could benefit when describing legacy instrumentation :-)

Obviously Rick is pointing to an internal copy for discussion purposes.

Um. Not obvious. The Thesaurus is available from:
The acknowledgements state:
"Version 1.1 compiled for the International Astronomical Union,
Commission 5 (Documentation)"
And indeed the Commission 5 WG on Libraries (http://www.eso.org/gen-
fac/libraries/IAU-WGLib) claims stewardship of the Thesaurus.
However, Commission 5 also is home to the VO WG and presumably the
two WGs would work together (much as Semantics and VOEvent do) to
resolve issues crossing their two domains. Presumably we should
contact the Libraries WG chairs (http://www.eso.org/gen-fac/libraries/
IAU-WGLib/chairpersons.html) when there is a solid version ready for
It seems to me that all by itself, an IVOA enhanced IAU Thesaurus
comprises a useful work product that is likely to be of interest to
the community. In general, the IVOA benefits from, and is
responsible to, the same IAU satrapies as the rest of astronomy.
