Clearly Defined
Clearly Defined is an open-source service that curates and shares license and security metadata for software components. It aggregates data from ClearlyDefined's community contributions, package registries, and source repositories to provide accurate licensing information, security advisories, and provenance details for npm, Maven, NuGet, PyPI, and other ecosystems. Teams use it to verify open-source compliance, assess component risk, and contribute missing metadata back to the community database.
