SPDX provides a license list for commonly used open source license - the SPDX License List. SPDX also supports defining licenses within the SPDX document using a LicenseRef syntax defined in section 6 of the SPDX specification. In the next release of SPDX, we plan to introduce a mechanism for other organizations or individuals to maintain lists of licenses outside of the SPDX license list, but allow those licenses to be valid without requiring the text to be in the SPDX document itself. This enhancement has been documented in the SPDX specification issues list. This project automates the registration and management of the namespaces.
