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
