About

JSON Schema is a vocabulary that allows you to annotate and validate JSON documents.

It's used by Google, Microsoft, Amazon, Mozilla, SAP, IBM, HM Government, NIH, and many others.

Used by webpack and eslint, with the main implementation weekly download of more than 20 million.

We're always looking for feedback from users and implementers, currently specifically on Vocabularies, a new concept in JSON Schema which allows for the formalised extension of JSON Schema.

More broadly, we're also looking to focus on educational resources, making sure they are consistent, up to date, and use developer friendly language, before we re-group to start work on the next draft.

JSON Schema is baked in to the worlds most popular editor, VS Code (according to the StackOverflow developer survey 2019).

JSON Schema is used as the means to specify payload data in the Open API Specification, which is the defacto API specification language today.

This project develops the JSON Schema specification, but does not develop any specific implementations.
