I discovered your project from https://github.com/gold-standard-phantoms/bids-pydantic/ which produces pydantic model from our BIDS standard metadata descriptor files such as https://github.com/bids-standard/bids-schema/blob/main/versions/1.9.0/schema/objects/metadata.yaml after a few ad-hoc transformations using your library. But there is now relatively new kid in the sandbox -- the https://linkml.io/ which provides a metadata description in yaml files expressive enough to then export in a variety underlying serializations like pydantic , jsonschema etc.

Thought to drop here to possibly see adoption for the "export" functionality.
