Ecma TC54

Software and System Transparency

Standardizing core data formats, APIs, and algorithms that advance software and system transparency

About TC54

Ecma Technical Committee 54 is chartered to standardize the OWASP CycloneDX Bill of Materials specification, standards and algorithms that advance transparency and identity, and the sharing of transparency information across the supply chain.


TC54 welcomes contributions from the community. We encourage organizations and individuals to contribute to existing proposals, documentation, and specification feature ideas. To participate in TC54 meetings as a member, join Ecma.


ECMA-424 standardizes the CycloneDX v1.6 Bill of materials specification. TC54 is actively working on additional standards which will be listed here in the future.
