STAC: Add 'url' for the processing software

[l0b0]

@billgeo commented on Mon Nov 01 2021

User Story

So that we can easily find the software that created a dataset we would like software URL for the 'processing software' in addition to the software name and software version.

Additional information

The processing extension currently has a string that can contain dictionary of values for software name and version.

See discussion on Slack here: https://linz.slack.com/archives/CN7F6HP2Q/p1635731683032700

Tasks

• Design some implementation options
• Draft one or more PRs with schema and documentation changes
• Test options with LINZ users

This is already supported by the processing schema - you can literally put any string property inside processing:software. name/version are just suggestions, not actually required (or even named) by the schema.

To be fair, this is a really bad idea - we'd have to create our own ad hoc meaning for the fields, and would have to put more than one value into a single string.

Blocked by stac-extensions/processing#6 and stac-extensions/processing#9.

[billgeo]

Looks like those two blockers may have been resolved by stac-extensions/processing#18 ? Are you to confirm this or establish if this is still blocked @l0b0 ?

[l0b0]

Neither of them were resolved. I've rebased stac-extensions/processing#6, and it's ready to merge. Once that's done I'll work on getting stac-extensions/processing#9 merged, since that should fix some issues with the current schema.
