IVOA Note on UCD maintenance

[Ana Ines Gomez de Castro]

Dear Andrea,

I've read the document and have some questions (maybe because I didn't 
attend the InterOp meeting). Here they are!

1. Why do you need two bodies "the scientific board" and the "semantics 
WG" to approve a new UCD?. Do you envission the SciBoard a "technical 
body" and the "Semantics WG" a "political-coordinating body"?

>From our previous experience, I think that to accept a new UCD we require:
- To test that the proposed new UCD cannot be made as a combination of the
already existing.
- To check that it is scientifically meaningful
Is the SciBoard going to be responsible of both duties?

2. I assume that the rigidity in the updating of the UCD list (the
list is updated during the InterOp meetings) is caused by the fact
that once a new UCD is accepted the data providers have to include it
in their "protocols", am I right?

3. Concerning the web based form... don't you think that it would be
good to have a Comments field where the "history" of the UCD 
approval/disapproval is recorded?. It is feasible that a scientist,
after receiving the notification of "rejection" answers to the SciBoard
providing new reasons for the inclusion of the UCD word, eventually some 
of these reasons maybe relevant and the SciBoard may reconsider the 
rejection.

I have not the slighlest idea about the degree of activity we might
expect from the Community BUT it maybe a good policy to keep all the
"rejected UCDs" in data base so, any time someone wish to propose a new
UCD, the data base can be cross-checked so some time can be saved to
the  Chair of the SciBoard. Maybe this list could be accessible to the 
Community.


4. I do not understand well why on the on hand, it may be necessary to
insert rapidly a new UCD (with the "temporary namespace "ivoa:"") and
at the same time accept that the list of UCD's is updated in time-scales
of InterOp meetings.

Hope it helps!. Please, do not waste time answering the questions that
have been already discussed at the InterOp meetings, just let me know.


Cheers,

Ana
