What does the "provenance" variable mean? #4

Open rsignell-usgs opened 6 years ago

rsignell-usgs commented 6 years ago

The provenance variable is present in all datasets, but depends on time and has values like 'fdd3774e-49bd-4908-9cfa-f0a1e664f486'. Is this an index into some other database table that describes the provenance?

Example: https://erddap-uncabled.oceanobservatories.org/uncabled/erddap/tabledap/CE01ISSM-RID16-03-CTDBPC000-ctdbp_cdef_dcl_instrument-telemetered-deployment0007-tabledap.htmlTable?time%2Cprovenance&time%3E=2017-06-14T00%3A00%3A00Z&time%3C=2017-06-21T23%3A35%3A40Z

the provenance variable holds the UUID of the UFrame sub-job process used to create the L0/L1/L2 products. It's not of much/any use, but I wanted to include it since it's included in the UFrame produced NetCDF file.

@rsignell-usgs unless you have objections, I will be removing this variable from the datasets going forward.
