EPN-TAP Proposed Recommendation: Request for Comments

EPN-TAP is a protocol used to describe and access data related to the study of the Solar System.

This document defines the EPN-TAP framework, which is using TAP with the EPNcore meta- data dictionary. The EPNcore metadata dictionary defines the core components that are necessary to perform data discovery in the Solar System related science fields. It includes keywords to describe data products coverage (temporal, spectral, spatial, photometric), origin (instrument, facility), content (target, physical parameters), access, references, etc. Its implementation with TAP (Table Access Protocol) is presented, including service registration guidelines. Topical extension metadata dictionaries are also presented.

As one of the document authors, I am basically happy with the text. But before recommending acceptance, I would like to see one EPN-TAP service that passes all validation checks. -- MarkTaylor - 2021-10-04

I have updated the Reference Implementation section, and I have listed several services passing all validation checks. -- BaptisteCecconi - 2021-10-28
