# Overview

[LinkML](https://linkml.io) is the language the sidecar's schema is written in. Both skills name linkml.io as the canonical site for what LinkML means: [schemas](https://linkml.io/linkml/schemas/) for the language and [generators](https://linkml.io/linkml/generators/) for what is generated from it.

In a sidecar the schema is one YAML file, or a few modules, and everything else is generated from it: the JSON Schema, Pydantic and dataclass models, OWL and SHACL, TypeScript and the docs site, one `just` recipe each.
