ExPRES Provenance file

[CorentinLouis]

Need to automatically create a provenance file, that will contains all data provenance (including, e.g., kernels name). This file needs to be created by uws, while running the “archive” simulations

[BaptisteCecconi]

(Example for Juno processing)

The provenance metadata should contain, at least:

• the version and branch of the ExPRES code (ie, commit id?)
• the meta kernel (and/or explicit list of kernel) used for ephemerides computation (eg “JUNO Archive” vs “JUNO Latest”).
• the WebGeoCalc API endpoint URL.
• the date of ephemerides computation (retrieval).

When computing the product of the ExPRES-Archive dataset:

• if current date > last date of “JUNO Archive”, then we use shall use “JUNO Latest”

When recomputing/updating products:

• get the last date of “JUNO Archive”
• recompute all files where the kernel was set to “JUNO Latest” at a date < current last date of “JUNO Archive”
