This directory defines public conformance vocabulary, self-declaration rules, official certification rules, and the official Sigma conformance registry.
Independent implementation of public SRS/SRIP normative requirements is permitted under the public specification terms.
Self-declared conformance is not official certification and must not be presented as endorsement, approval, partnership, or certification by Sigma Stratum.
Official Sigma certification requires review, approval, and listing in the official Sigma conformance registry.
