Collaboration on Source Catalogue DM, ADQL and SkyNodes

[Maria A. Nieto-Santisteban]

Hi,

This is great news!

There are three things I would be interested in knowing:

 - How does Catalogue Data Model used look like, especially what is the 
common set of attributes and the associated metadata.

- What are the plans about registration? Will these nodes (Basic?) be 
registered and therefore accessible through Open SkyQuery? How many?

 - The cross-match functionallity. Are you planning on a 2 catalog 
cross-match or n-catalog cross-match? How does the cross-match function 
look like?

Cheers

Maria
