JSONstä

JSONstä is a fictional data interchange format designed as an extension of JSON to address multilingual data and lightweight metadata while preserving simplicity.

It maintains a JSON-like core syntax for objects and arrays, but adds optional type annotations, a locale field for strings, and metadata attributes such as units and descriptions.

History and status: JSONstä originated in speculative discussions among developers and researchers as a thought experiment. It is not an official standard and has no formal governance.

Syntax and example: The format remains largely JSON-compatible; an item might appear as { "name": "Alicia", "_type": "string", "_locale": "es-ES", "age": {"value": 30, "_type": "integer"} }.

Usage and tooling: Some prototypes provide JSONstä parsers and validators; it is used mainly in demonstrations or research and is not widely deployed in production systems.
