 JSON Schema is a specification for 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 it can be
 modified, much like what XML Schema provides for XML. JSON Schema is
 intended to provide validation, documentation, and interaction control
 of JSON data.

 This package contains the Python 3.x module.
