Every result keeps the notice it arrived with.
A discovery result can combine the sources below. Graduna stores the source alongside the record, so the applicable notice can travel with it when you export or publish.
- Overture Maps Foundation
Places and administrative divisions. Overture Places includes sources offered under CDLA Permissive 2.0 and, in current releases, other source-specific licenses such as Apache 2.0 and CC0. The release-specific attribution and licensing table is authoritative.

If you export or publish results, keep the notice for the source each record came from. The source is stored on the record for exactly this reason.
