Questions tagged [jsonschema]

A JSON Schema is a JSON document (an object) which defines constraints on what other JSON documents (the instances) should obey; it can also be used to interpret instances so as to provide links to external resources (hyper schema).

JSON (JavaScript Object Notation) Schema defines the media type application/schema+json, a JSON based format for defining the structure of JSON data.

JSON Schema provides a contract for what JSON data is required for a given application and how to interact with it. JSON Schema is intended to define validation, documentation, hyperlink navigation, and interaction control of JSON data.
