The Software Package Data Exchange® (SPDX®) specification is a standard format for communicating the components, licenses and copyrights associated with software packages.

The SPDX standard helps facilitate compliance with free and open source software licenses by standardizing the way license information is shared across the software supply chain. SPDX reduces redundant work by providing a common format for companies and communities to share important data about software licenses and copyrights, thereby streamlining and improving compliance.
