Open Source

In use for a decade as the de facto standard for communicating software bills of materials, The Linux Foundation has announced that the Software Package Data Exchange (SPDX) specification has been published as ISO/IEC 5962:2021 and recognized as the open standard for security, license compliance and other software supply chain artifacts. 

Software bills of materials are used to communicate information in policies or tools to ensure compliant, secure development across global software supply chains. 

"SPDX plays an important role in building more trust and transparency in how software is created, distributed and consumed throughout supply chains," said Jim Zemlin, executive director, the Linux Foundation, in a press release. "The transition from a de-facto industry standard to a formal ISO/IEC JTC 1 standard positions SPDX for dramatically increased adoption in the global arena. SPDX is now perfectly positioned to support international requirements for software security and integrity across the supply chain."
