This page defines attribution requirements for Sigma Stratum public specification materials, research corpus documents, and documentation excerpts.
Attribution to Sigma Stratum, SRS, or SRIP does not imply certification, endorsement, partnership, or authorization to use Sigma marks as product identity.
Citation of SRS/SRIP does not create official conformance status.
For licensing context, see:
Every reuse of Sigma Stratum text, figures, excerpts, public specification materials, or research corpus materials must include attribution appropriate to the applicable document license.
Attribution should include:
When citing or implementing public SRS/SRIP materials, identify the SRS/SRIP document and version used.
Suggested format:
Based on the Sigma Runtime Standard public specification layer, Sigma Stratum Research Group, document/version/date as cited. Source: https://sigmastratum.org.
If making a compatibility or self-declaration statement, also identify supported SRIPs, unsupported SRIPs, known deviations, and evidence artifacts where required by the applicable conformance rules.
Research-origin materials may carry CC BY 4.0, CC BY-NC 4.0, or another per-document license. The license stated in the source document controls.
For DOI-linked research materials, cite the DOI and named author when available.
Example:
Tsaliev, E. (2025). SIGMA Runtime Architecture v0.1. DOI: 10.5281/zenodo.17703667. Sigma Stratum Research Group.
Commercial use of CC BY-NC materials requires separate authorization unless the source document states otherwise.
Attribution identifies source and provenance. Sigma Runtime product assets, certification badges, and Sigma marks follow their own policies or written terms.
Attribution does not imply certification, endorsement, partnership, product approval, official compatibility, or permission to use Sigma Stratum, Sigma Runtime, ∿, certification badges, or official compatibility language as product identity.
Redistributed or adapted materials should preserve source attribution, license notices, version references, and DOI references where applicable.
Derived documentation should not imply official Sigma certification or endorsement unless reviewed, approved, and listed through the applicable certification or conformance registry process.
