Semantics news

[Andrea Preite Martinez]

Dear all,

here some news:

UCDs:
- The new UCD1+ list of words (Version 1.23) is an IVOA-REC since  
April 02. You can find the document in the IVOA Document repository.

- As you can see in Appendix B of the document, 12 words have been  
deleted since last REC (Rec20051231). The following is the list of  
deleted words, with the corresponding replacements:

deleted:           | replacement:

phys.atmol.damping | phys.damping
phys.atmol.qn.I    | phys.atmol.qn
phys.mol.qn        | phys.atmol.qn
time.event         | time.duration
time.event.end     | time.end
time.event.start   | time.start
time.expo          | time.duration;obs.exposure
time.expo.end      | time.end;obs.exposure
time.expo.start    | time.start;obs.exposure
time.obs           | time.duration;obs
time.obs.end       | time.end;obs
time.obs.start     | time.start;obs

- This opens the problem of upgrading the content of archives already  
using UCDs and/or the problem of keeping track of different versions.

- You can find the list of words with the updated tools at the CDS  
page http://vizier.u-strasbg.fr/UCD/.

- As requested by many of you, a syntax-validate tool has been built  
and it works. It will be soon available on-line (for the moment it?s  
only running on my machine!)

Vocabulary:
- A Note on Astronomical Keywords in the era of the Virtual  
Observatory has been recently uploaded in the IVOA Document repository  
(and WG page). Comments are welcome.

Ontologies:
- I recently moved the Note on Ontology of object types to the level  
of WD, but this does not mean that we envisage to have an IVOA  
standard ontology, at least for the time being.

- We are working on use cases: unknown concept classification,  
browsing of the knowledge, . . . ideas are welcome.

Beijing InterOp:
- We have 2 sessions: roughly one for UCDs and one for Ontologies.

- There is still room for one or two contributions per topic: please  
let me know!!

Cheers
Andrea
