This project is under a lot of flux -- I want to add zarr version 3 support to this project, but the reference python implementation doesn't support version 3 yet. Also, the key ideas in this repo may change in the process of being formalized over in this specification (currently just a draft). As the ecosystem evolves I will be breaking things (and versioning the project accordingly), so be advised!
pip install -U pydantic-zarr
See the documentation for detailed information about this project.

# this is a pydantic model
