📜Data License

NEW

Also known as: Data Licensing

A legal instrument that specifies permissions and restrictions for using, sharing, and modifying data.

DESCRIPTION

Data licenses clarify how data can be accessed, reused, redistributed, and combined. They define attribution, share-alike, commercial use, and derivative work requirements. Open licenses maximize reuse, while proprietary licenses restrict rights. Choosing a license affects interoperability, compliance, and downstream obligations. Standard licenses like ODbL or Creative Commons provide predictable terms. Clear licensing underpins trustworthy sharing in data commons, marketplaces, and collaborations.
