vo-dml in votable

[Pierre Fernique]

Dear App members,

May I emphasise the Gerard's mail.

VOTable is a key element of the VO. The VODML serialization in VOTable 
discussed here will have probably a big impact on our standards and 
applications  - for the best I hope. So please take time to look 
carefully the Gerard's proposal and do not hesitate to bring your 
contribution.

The fastest ways to have an clear idea of the goal is to have a look on 
this example and the 2 other variants:

http://volute.googlecode.com/svn/trunk/projects/dm/vo-dml/doc/samples/votable/VOTable_Prop4a.xml

Thanks for your contribution
Best regards
Pierre Fernique
