`fairdm.management.commands.seed_licenses`#

Seed the licences FairDM recommends.

django-content-license ships the Creative Commons licence text and declines to load any of it, since curating which licences a portal offers is a decision for the portal. Nothing in FairDM loaded that fixture either, so a freshly migrated portal had no License rows: FAIRDM_DEFAULT_LICENSE resolved to nothing, and any form built over License.objects.all() was a required field with an empty queryset.

This command creates the three licences FairDM recommends (CC0 1.0, CC BY 4.0 and CC BY-SA 4.0), reading their name, description, licence text and canonical URL out of django-content-license’s own fixtures/creativecommons.json.gz rather than retyping them. The NC and ND variants that fixture also carries are not seeded: they fail the Open Definition, and a framework named for reusability should not present “no derivatives” as a recommendation for research data. A portal that wants one adds it itself.

A portal runs it on every deploy, beside sync_vocabularies, so an existing portal picks it up on its next one. It is idempotent, keyed on License.name (unique=True on licensing.models.License), and leaves alone a licence a portal has already edited under one of these three names.
