IVOA KDD-IG: Template datasets for algorithm benchmarking




Who's interested?

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:

  • Catalog of sources, each with ID, position, magnitudes, ... more
  • Light curve of source, with time, magnitude, upper-limit observations, ... more.
  • Image, with WCS, calibration, ...more.

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?).

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. -- Roy
