July 23, 2025 - The jsonschema is a Python library used for validating JSON data against a schema. A schema defines the structure and constraints for JSON data, ensuring that the data adheres to specific rules and formats.

The JSON object {} is simply the Python dict {}, and a JSON Schema like {"type": "object", {"properties": {}}} is really an assertion about particular Python objects and their keys. ... The $ref keyword is a single notable exception. Specifically, in the case where jsonschema is asked to resolve a remote reference, it has no choice but to assume that the remote reference is serialized as JSON, and to deserialize it using the json module.
