<p>
It would seem to me that these points below are intimately related: (3) the templates and (5) working with IVOA, meaning choice of data models and formats. I would see the following as interesting data objects for the KDDIG:
</p>
<ul>
<li> Catalog of sources, each with ID, position, magnitudes, ... more
<li> Light curve of source, with time, magnitude, upper-limit observations, ... more.
<li> Image, with WCS, calibration, ...more.
</ul>
<p>
In each case, there is an IVOA approach to these things through the spectrum data model (VOTable + Utypes). There are also other formats for these things that are not IVOA approved. And of course there is always a call for the stripped-down CSV (just gimme the data). The archive can have many format choices (so what are they?).
</p><p>
One could also say that the formatting is easy once the data is in the database, which avoids choice of a specific syntax. But the *semantics* of that database schema must enable the *semantics* of every proposed output format.
