# Overview

A schema language is a formal language for describing the structure, constraints, and data types of a configuration. Config schemas are defined in a supported schema language to validate config instances before deployment.

Currently, the following languages are supported:

* [JSON Schema](/cfg-mgmt/primitives/schemas/languages/jsonschema) (draft 2020-12)
* [CUE](/cfg-mgmt/primitives/schemas/languages/cue)

The following sections cover key integration points for each language.
