Gordian Envelope

Protocolo Semântico e de Dados

Specification for a "smart document" structured data format providing hierarchical binary documents with built-in Merkle-like digest tree, deterministic CBOR encoding, signatures, encryption, and selective elision/redaction. The defining feature is hash-based elision: holders can selectively reveal or hide parts of a document for specific recipients without invalidating the digest tree, supporting both privacy-preserving disclosure and cryptographic proofs of original content. Foundation for the Blockchain Commons "Gordian" stack and underlying format for XID controller documents, Gordian Clubs, and GSTP transport. Sub-specs include Known Values (vocabulary), Permits (cryptographic access control), GSTP (Gordian Sealed Transaction Protocol), and ESC (Encrypted State Continuation)

Protocolo Semântico e de Dados Atributos

Origens Blockchain Commons; built atop dCBOR foundation
Banco de Dados N/A — data format specification; envelopes can be stored in any database, file, or transmitted over any channel
Linguagem de Consulta N/A directly — Envelope structure supports selective-disclosure queries via inclusion proofs; expression evaluation supported via BCR-2023-012 but not a general query language
Formatos de Dados CBOR (deterministic via dCBOR); SHA-256 Merkle digest tree; recursive subject-predicate-object semantic triples
Edição Colaborativa em Tempo Real N/A — data format, not a collaborative editor
Edição de Texto Rico N/A — data format; rich-text concerns belong to applications using Envelope
Suporte Móvel Yes (via Swift and Rust libraries)
Suporte Web Yes (via TypeScript ports)
Aplicativos Nativos Yes — used in Gordian Seed Tool (iOS/macOS), Gordian Coordinator, and other reference apps
Termos Open standard, BSD-2-Clause Plus Patent License
Fundos Unknown — funded under Blockchain Commons general operating budget (GitHub Sponsors and corporate sponsors); specific Envelope allocation not separately published
Baseado Em dCBOR (Deterministic CBOR Application Profile); RFC 8949 (CBOR); SHA-256
Compatibilidade com a Web Semântica Subject-predicate-object model derived from RDF; Known Values include Schema.org assignments; cross-references possible to RDF/JSON-LD vocabularies
Maturidade / Padronização do Protocolo IETF Informational Draft (draft-mcnally-envelope-10, Sep 30, 2025, Experimental track); W3C CCG discussion ongoing; production-ready libraries
Tipo de Vocabulário / Ontologia Smart document structure with Known Values registry (predicate vocabulary); subject-predicate-object semantic triples
Padrão de Uso Foundation for higher-level Blockchain Commons specs (XID, Gordian Clubs, GSTP, ESC); used as a structured data carrier in airgap protocols, credential systems, autonomous cryptographic objects
