Why some uses need review
AI model training. The ODbL distinguishes derivative databases (share-alike) from produced works (attribution only). Whether a model trained on the database is a derivative database or a produced work is not settled. A human reviewer should confirm this use for your case.
Duties
- give attribution / keep the notice
- license notice
- release distributed derivatives under the same license
- keep open
Notes
- Covers the database; contents may carry their own rights (section 2.1).
