√ Rearrange data products (jpeg vs fits), add previews, + check descriptions (from local db)
Compute pointing (mostly phase) + Fix image orientation?
Enlarge contents (other existing digitized images)
Phase angle can be retrieved from Miriad.
Orientation is more difficult.
|Updated to v2, to be tested.|
Sept 2017: rebuilt with mixin / grammar, queries LESIA database in SQL during ingestion.
|Planets||Main characteristics of planets||From IAU / Allen reference data||PADC|
√ Declare properly in registry (issue with referenceURL field)
To be enlarged with satellites info (see below)?

|spectro_planets||Planetary spectra||Low res, global spectra of planets and satellites. References for ground observations, provide only 1 or 2 typical spectra/object (from selected archives). Includes historical data of interest||LESIA, Erard|
√ Identify sources; currently THN library + USGS + IRTF + JSNU + occasional LESIA data
√ Convert files to documented VOtable, not fits (for use in CASSIS) - this is tricky in some cases
√ Collect complete info from original papers
Spectral calibration unchanged, not homogeneous - but solar spectra provided also
See interoperability with Planets service.
Add ephemeris from Miriad in the table (or datalink to Miriad)
|IRTF_Orton||IR telescopic images of Jupiter||Images from IRTF, Hawaii, in support of Juno||PADC/LESIA, Cecconi|

|PSA||ESA's Planetary Science Archive|
Complete archive implemented early 2018.
Only ~ 6 Mfiles among 18 in 2018 (Rosetta RPC filtered out - this slowed down the first draft, and provided no usable information)
Difficult on ESA side to retrieve description parameters: PDS/EPN-TAP correspondance is very much dataset dependent.
Get parameters from files/datasets?

Demo for use of images + coordinates planes (include only cubes?)
Congruence with HST_planets

Pb: file extensions are not "fits", so they won't open automatically
|Titan ground based observations||Historical work from the 90s only?||LESIA, Henry|
|First, recover data on old machines (from M. Combes). |

|(TBC)||?||List of codes available on-line for Planetary Science||Paris ???|
|Could be based on IDIS resource list from FP7 - has to be cleaned up and modernized though. Not EPN-TAP.|
• Or instead, use github of OpenPlanetary
Potential issue with maintenance.
Would help wait for computing on demand system
