## Description

This project provides the JSON Schema Specification, a standard for annotating and validating JSON documents to ensure consistent data structures across different systems. It serves as a data validation standard and an interoperability standard, establishing a common language for exchanging data definitions between different programming languages and platforms.

The specification includes a machine-readable framework for defining JSON vocabularies, which describes the expected types, formats, and structures of data objects. It enables the creation of standardized, machine-readable documentation to ensure clarity and consistency in technical data representations.

The framework covers a wide range of capabilities, including declarative structure definition, recursive schema composition, and meta-schema validation to verify that schemas are syntactically correct. It also provides mechanisms for keyword-based constraint mapping, data document annotation, and the standardization of validation outputs to maintain interoperability between different processing tools.
