Re: IVOA Note on UCD maintenance

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
