EPN-TAP

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.
