JSON Structure is one of 13 APIs that [API Specifications](https://apis.io/providers/specifications/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include JSON Structure, Schema, Data Modeling, Code Generation, and Specification Language. The published artifact set on APIs.io includes API documentation and a GitHub repository.

JSON Structure is an emerging open specification that extends and complements JSON Schema with a clearer, more code-generation-friendly type system designed for data contracts and modeling. It introduces structural primitives intended for cross-language model generation. The project is community-driven and Apache 2.0 licensed.
