Introduction
This section gathers various actions to access data content from EPN-TAP services, including developments during EPN2020.
Only on-going discussions have been moved here.
VESPA user search interface / portal
• The main user interface is located here: http://vespa.obspm.fr
It queries all services at once (other modes are available), formats the results, and connects with VO tools and other environments (ObsParis)
Roadmap for developments: VESPA Portal
• A local VESPA portal can be installed on your machine. This is intended to access services which are only available locally (e.g., on a Virtual Machine) and are not exposed on the Internet.
• Generic TAP clients are also usable (e. g., TapHandle, TAP Library, TOPCAT, and Aladin from v10) but do not provide specific support for EPNCore-based services
EPN-TAP library(ies)
EPN-TAP client libraries have been developed and included in some VO tools during EPN2020: CASSIS, 3Dview (IRAP/CNRS)
Java implementation: https://gitlab.irap.omp.eu/OV-GSO-DC/EpnTAPClient/
PHP/JavaScript implementation: in dev, TBD
Added SAMP plug-ins
Several tools have been updated during EPN2020 to send / receive data through SAMP:
• A plug-in provides SAMP connectivity to QGIS v2.x (Jacobs / GEOPS) — EPN2020
This works under Debian. A pre-packed Virtual Machine is available from JacobsUni with Debian/QGIS/plug-ins installed, for use with other OS
A working version under Mac OS has been seen in April 2018.

https://github.com/epn-vespa/tutorials/blob/master/vo_qgis_plugin_2/vo-qgis-plugin-2.md
• This has been updated for QGIS v3 later: QGIS with VO plugins
• A plug-in provides SAMP connectivity to ImageJ (ObsParis) - currently in input only
Installation and use: ImageJ
• MATISSE has been provided with SAMP during EPN2020 (ASI/ASDC): Update on integration MATISSE-VESPA
• Autoplot has been provided SAMP during EPN2020 (Iowa Uni): Available tools
Google Sheet Add-on
Allows to query EPN-TAP services from on-line documents: easy access interface through on-line Excel-like sheet (Graz)
The preview of the tool can be found here >> https://drive.google.com/open?id=0B5hOkAv922Z6OVlQLUJENDQxRTg
A short tutorial describing basic features and usage can be found here: https://drive.google.com/open?id=0B5hOkAv922Z6OU9fN3RyQ0JRZGc
(EPN2020 dev)
Links to various environments (tutorials)
Are being defined:
EPN-TAP files retrieving interface
A set of web services providing file URL in JSON format, intended for pipeline processing
See this page: File grabbing interface (fgi)
Python interface
Limited to grabbing VOtables sent from VESPA
Info here: VESPA usage for non VO people
Baptiste's exercise during DPS/EPSC 2016 / Astropy for Planetary Science session ("SAMP in python .ipynb")
IDL interface
Limited to reading VOtables downloaded from VESPA
Info here: VESPA usage for non VO people
Stéphane's exercice to read VOtables from IDL - tuto TBD
