  • EPN-TAP is a VO access protocol dedicated to Planetary Science data. It is based on the TAP mechanism from IVOA, completed with sets of parameters and associated lists of values. In this regard, it is similar to ObsTAP but with a different scope.
  • EPN-TAP version 2 is a major update of the protocol to accommodate larger services and simplify setup and use of data services. All parameters are described here.

...

Parameters which must be provided

are now clearly identified - those are not only mandatory, they also must provide a value.
They are mostly related to service description and granule identification.

+ See notes below the table.

Thematic extensions

Some science fields will require optional parameters, which need to be used consistently between services addressing the same field. Such extensions have to be designed by sub-groups involved in the corresponding data services, either as providers or users. This includes:

  • Lab spectroscopy: parameters to describe mineralogical samples (and possibly other samples)
  • OrbitalSolar System objects: covers orbital/rotational parameters and , physical properties of Solar System bodiesResults of planetary 3D modelling run, and taxonomy
  • APIS: contains parameters for observing programs
  • Contributive works / observing programs: enlargement of APIS extension to other data
  • Exoplanets / planetary systems properties
  • Bibliographic entries? May be manageable otherwise, through bibcode / doi interpretation
