SPDX is an open standard for communicating software bill of material information, including provenance, license, security, and other related information. SPDX reduces redundant work by providing common formats for organizations and communities to share important data, thereby streamlining and improving compliance, security, and dependability.
The mission of SPDX is to develop and promote open standards for communicating software bill of material information, including provenance, license, security, and other related information.
The vision of SPDX is to reduce redundant work by providing common formats for organizations and communities to share important data, thereby streamlining and improving compliance, security, and dependability.
SPDX is an open source project hosted by the Linux Foundation. The grass-roots effort includes representatives from a diverse set of organizations—software, systems and tool vendors, foundations and systems integrators. Work is done by two sub-groups: the tech team and the legal team. There is also a monthly general call which provides an overview of progress on the entire project. For more information about getting involved, see the Participate page.
The SPDX project is composed of:
- The SPDX Specification itself
- The SPDX License List (including exceptions, matching guidelines, license IDs, and license expression syntax)
- SPDX tools and libraries for working with the SPDX documents and SPDX License List
- SPDX represents data in formats that are both machine- and human-readable.
- SPDX focuses on collecting and communicating facts; and provides a framework to make assertions about those facts.
- SPDX makes no legal interpretations (of licenses or license compliance).
- SPDX facilitates the efficient exchange of metadata in the supply chain.
