The version 1.2 of VOTable, already in discussion since more than
2 years, introduces the link between data models and VOTable
(via the utype); among the data models, STC is especially important
in the context of astronomical data, and a dedicated note on
"Referencing STC in VOTable" is, I hope, in a more or less final
Two working drafts have been posted (section "Working Documents"
on the VOTable page of IVOA at
proposed note on "Referencing STC in VOTable"
draft version of the version 1.2 of VOTable
Both documents are open for discussion; my hope is that the version
1.2 of VOTable can enter the final stage of the Recommendation path
for the Baltimore meeting. The main differences between VOTable1.1
and VOTable1.2 are:
* the COOSYS is deprecated, in favor of a reference to the Space-Time
Coordinate (STC) data model
* the INFO element (INFO) is made similar to the PARAM element, i.e.
o may have attributes utype, ucd, ID, ref, unit
o accept sub-elements DESCRIPTION, VALUES and LINK
* the INFO element may occur after before the closing tags /DATA,
/TABLE and /RESOURCE and /VOTABLE (enable post-operational diagnostics)
* naming conventions of GROUP elements which specify some properties
of a relational schema.
This message is mailed to both IVOA WGs "VOTable" and "DataModels"
(the latter for the implication of STC). It's NOT necessary to send
your message to both WGs -- please mail your comments to
votable at ivoa.net
Looking forward for interesting discussions, and let's meet in
Baltimore in late October,
