Hello,
I have placed on the IVOA wiki a PDF version of the latest document
on UCD: http://www.ivoa.net/internal/IVOA/IvoaUCD/WD-UCD-20040426.pdf
This document describes the motivations and procedure to evolve
the first generation of UCD into a new scheme called UCD1+.
The new scheme has been quite successfully tested on VizieR. It also
includes inputs from other fields, like the latest SIAP discussions.
As the UCD1+ vocabulary is likely to evolve faster than the reference
document itself, the reference lists are available online, together with
old
versions and history of changes:
http://vizier.u-strasbg.fr/UCD/lists/
The document currently has a Working Draft status, but the idea is
to promote it to an IVOA Proposed Recommendation. This can be done
once agreement is reached within the discussion group, if I understand
well the IVOA document lifecycle.
So... time for discussion now !
Sebastien.
