JSONStandard

JSONStandard is a formal specification for JSON data interchange intended to improve interoperability across software components. It defines a canonical serialization form, a data model, and a schema language designed to complement established JSON standards such as RFC 8259 and ECMA-404.

Key features of JSONStandard include a deterministic object member order for canonical encoding, defined rules for whitespace and numeric representation, and a JSONStandard Schema for describing and validating data structures. The specification also allows optional metadata annotations at the top level to convey provenance, versioning, and usage constraints.

As of this writing, JSONStandard remains in the draft stage, with reference implementations in several languages and ongoing conformance tests. Proponents describe it as suitable for data exchange scenarios that require reproducible serialization, deterministic comparisons, and schema-driven validation.

Relation to existing standards: JSONStandard does not replace RFC 8259 or ECMA-404; instead it offers optional extensions and a canonical encoding that can be used to improve cross-language interoperability, data caching, and integrity checks.

History and governance: The JSONStandard initiative was launched by a consortium of industry and open-source participants in 2021, with formal governance by a steering committee and a public review process.
