dCBOR

Protocolo Semántico y de Datos

Application profile for CBOR (Concise Binary Object Representation, RFC 8949) defining narrowing rules to achieve interoperable deterministic encoding across implementations. Where RFC 8949 leaves several encoding choices to the implementer (number canonicalization, NaN handling, floating-point representation, map key ordering), dCBOR specifies a single canonical form so that semantically equivalent data items always encode to identical byte streams. Underlying format for Gordian Envelope and several other Blockchain Commons specifications. Available as production-ready libraries in Rust, Swift, and TypeScript with CLI tooling

IETF Internet-Draft draft-mcnally-deterministic-cbor-17 (Feb 2026), intended status Standards Track; production-ready libraries with multiple third-party implementations

Tipo de Vocabulario / Ontología

Encoding profile (no vocabulary); narrowing rules over a general-purpose binary serialization format

Patrón de Uso

Foundation for Gordian Envelope, UR (Uniform Resources), XID, Gordian Clubs, and other Blockchain Commons specifications; used wherever byte-level determinism matters (signing, hashing, content addressing)
