I have an asset search result from Openverse, Smithsonian, Europeana or Wikimedia Commons: which field tells me its licence, which tells me what credit to give, and which fields must I not treat as final?

Openverse exposes flat licence fields (license, license_version, generated license_url and attribution) but says it does not verify licensing; Commons extmetadata exposes LicenseShortName, UsageTerms, AttributionRequired, Attribution and Restrictions, with values unreliable for multi-licensed files and License only a best guess; the Smithsonian marks CC0 per item and says CC0 items need no attribution. Each provider tells reusers to verify. Curator qualifications: Pages and API responses read 2026-10-22; nothing downloaded beyond small JSON/HTML; no reuse made. Europeana reusability page (Wayback) not re-read. Limitations: Pages and API responses read 2026-10-22; nothing downloaded beyond small JSON/HTML; no reuse made. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
