JSON Schema Specifications

2025.9.1 verified Tue May 12 auth: no python install: verified quickstart: stale

A Python package providing JSON support files from the JSON Schema Specifications, including metaschemas and vocabularies, packaged for runtime access as a referencing-based Schema Registry. Current version: 2025.9.1. Release cadence: Regular updates with recent releases in 2025 and 2024.

pip install jsonschema-specifications

Common errors

error ModuleNotFoundError: No module named 'jsonschema.compat' ↓

cause This error occurs when a project using an older version of `jsonschema` (pre-4.0) attempts to import the `jsonschema.compat` module, but the installed `jsonschema` package has been updated to version 4.0 or higher, where this module was removed.

fix

Downgrade the jsonschema package to a version below 4.0, for example: pip install 'jsonschema<4.0' or pip install -U 'jsonschema<4.0'. Alternatively, update your code to no longer rely on jsonschema.compat if possible.

error ImportError: cannot import name 'validate' from 'jsonschema' ↓

cause This error typically arises when attempting to import the `validate` function directly from the `jsonschema` package, which is not its primary location in newer versions, or due to version mismatches.

fix

Ensure you are importing validate from jsonschema.validate instead of directly from jsonschema: from jsonschema import validate. If the issue persists, try upgrading jsonschema to the latest version: pip install --upgrade jsonschema.

error jsonschema.exceptions.RefResolutionError: Could not resolve schema reference ↓

cause This error occurs when the `jsonschema` validator (which relies on `jsonschema-specifications` for standard metaschemas) cannot find or access a schema referenced by a `$ref` keyword, often due to incorrect paths, missing local files, or unconfigured remote resolvers.

fix

Ensure all $ref paths are correct and accessible. For local files, provide an appropriate base URI or load referenced schemas into the resolver's registry explicitly. For remote references, configure a custom resolver or ensure the URIs are resolvable. Consider using referencing.Registry to manage your schemas.

Warnings

breaking The `get_schema` function has been removed from the top-level `jsonschema_specifications` module, or its access path has changed, resulting in an `AttributeError`. Users previously calling `jsonschema_specifications.get_schema` will encounter this error. ↓

fix Consult the `jsonschema_specifications` documentation for the updated method to retrieve schemas. The `get_schema` functionality may have been moved to a submodule (e.g., `jsonschema_specifications.schemas.get_schema`) or replaced by an alternative API.

deprecated Support for Python versions below 3.9 has been deprecated. ↓

fix Upgrade to Python 3.9 or later to ensure compatibility.

breaking The function 'jsonschema_specifications.get_schema' has been removed or renamed. ↓

fix Update code to use the new API for accessing schemas; consult the library's release notes or documentation for the updated method of retrieving specifications.
