UCD IVOA standard : a few documents to read and review

[Mireille Louys]

Dear Semantics subscribers,

The list of terms for UCD is evoling regularly, due to new requirements 
in the Virtual Observatory framework and the astronomical domain at large.
if you want to know:

  * /where //is the most recent list of valid UCD terms ?/

         it is available in the current working draft currently in 
discussion on the semantics list at 
http://www.ivoa.net/documents/UCD1+/20170502/index.html
<http://wiki.ivoa.net/twiki/bin/view/IVOA/ReviewUCDlist2017May>        
you can provide your comments on the following discussion page : 
<http://wiki.ivoa.net/twiki/bin/view/IVOA/ReviewUCDlist2017May>http://wiki.ivoa.net/twiki/bin/view/IVOA/ReviewUCDlist2017May

  * /how the UCD //vocabulary is maintained in the IVOA?/

         The 'Note-UCDlistMaintenance-2.0-20170602" , mentioned below, 
is important to state /how /we will make this list evolve . The proposal 
describes the ways new         terms can be requested and validated.

  * /how can I suggest a new term if I did not find an appropriate word
    or combination of words in the existing list?
    /

         New terms can now be requested at this page : 
http://wiki.ivoa.net/twiki/bin/view/IVOA/RFMforUCD
         An answer and suggestion for usage if needed will be given on 
the same wiki page after  a short period of discussion in the 
Maintenance committee and the                         semantics WG.


Please review these documents so that we can proceed in the update of 
the process to curate the IVOA vocabularies.
Many thanks , Mireille Louys

> As discussed during the Semantics session in Shanghai, Mireille and I 
> have been working on a new version (V2.0) of the UCD List Maintenance 
> Standard. The basis discussed in Shanghai is to take advantage of the 
> newly introduced IVOA Endorsed Note process (see 
> http://www.ivoa.net/documents/DocStd/20170517) to facilitate the 
> updates of the UCD vocabulary. It is proposed to deprecate the UCD 
> list from Recommendation to Endorsed Notes, which can be updated to 
> the next version by TCG agreement instead of going through the whole 
> standardisation process. The Shanghai session participants insisted on 
> the need that the updates are made as quickly as possible, and the new 
> process allows to do that while keeping a formal procedure and 
> cross-WG check. Please note that Endorsed Notes, like Recommendations, 
> are published in the ADS, which ensures their visibility.
