@alexdunnjpl @nutjob4life holding on merging this for the time being. awaiting some feedback from our PDS DOI expert to ensure we are doing this right :-)

[jordanpadams]

@alexdunnjpl you may be able to just add the licensing metadata update to this PR in the meantime.

Behaviour as-implemented:

• new DOIs get GWorks and CC0 by default
• release applied with no rightsList attribute present in label data gets GWorks and CC0

• release applied with empty or other-valued rightsList attribute in label data gets whatever the label specifies.

  @jordanpadams ready to merge, pending your DOI MVP A-OK :sweat_smile:

@alexdunnjpl do we need to update the test data that is out there?

@alexdunnjpl do we need to update the test data that is out there?

@jordanpadams I'm not sure. No tests failed, so I'm not sure if it's within the scope of existing tests. I'll take a closer look at that test data early next week.

[jordanpadams]

merging. will poke at test data if anything breaks.

@jordanpadams I can't turn up any string references to these files and the commit histories are intractably-large in terms of identifying related files/modules/tests.

Given that tests aren't failing, I'd suggest it's not worth investigating further.
