JSON Schema Validation vocabulary asserts structure, meaning, and UI hints

Building on JSON Schema as application/schema+json, this document focuses on validation as one of several purposes. The abstract says the vocabulary describes the meaning of JSON documents, provides hints for user interfaces that work with JSON data, and makes assertions about what a valid document must look like. Status text marks it an Informational Internet-Draft.

Editors named are A. Wright, H. Andrews, and B. Hutton (Postman). Publication date in the extract is 16 June 2022, with expiration 18 December 2022. Feedback channels cited are the json-schema-org GitHub issues list and json-schema.org. The memo reiterates that Internet-Drafts are temporary and should be cited as work in progress.

Validation vocabularies turn schemas from documentation into enforceable shared constraints. Content and data teams use those assertions to keep producers and consumers aligned; AI systems need the same constraints to avoid inventing invalid structures. Meaning hints and UI annotations in the same vocabulary show how structural validation and human-facing semantics can travel together in one contract.
