+ Source Data Model

This page is a collaborative page to discuss the ongoing SourceDM draft.

Objectives:

• Create a simple (but useful) SourceDM definition that could help in the publishing of catalogues through VO protocols
• Support on the definition for catalogues metadata for near-future missions (e.g. Gaia, Euclid,…) and allow the mapping for old ones
• Support interoperability operations between protocols (SED creation, crossmatch operations, etc)

++Previous related effort Catalog data model

Currently, only a preliminary UML has been generated with the definition of basic metadata and how to connect to other IVOA existing models. Whenever the conections are shown, a full connection from the DM point of view can be considered.

Changes done:

• Magnitudes that come from different transients associated to Source
• IUAName extracted from class
• Better multiplicity display (not all the quantities are compulsory)
• Direct link to Provenance DM (?) (not done yet as not clear now as it is an ongoing DM)

Parallaxes and distances

Projects prefer to include parallaxes to distances due to the connection implies certain assumptions. A couple of papers distributed on

this issue.

To be discussed (mainly Arnold) how this can be mapped correctly in STC

Source Type

To be defined by Sebastian how this should be implemented

Quality Flag

Proposed for inclusion by Francois-Xavier Pineau. To be defined how to do it (Provenance?). Mark to advise
