zarr-metadata
Types, models and validators for Zarr metadata documents, with minimal dependencies.
zarr-metadata is developed in the
zarr-python repository
and released independently of zarr. Install it with:
pip install zarr-metadata
What this is
A collection of data structures and routines that closely model the metadata rules in the Zarr v2 and v3 specifications and in zarr-extensions:
TypedDictshapes for every document and configuration.- Immutable document models. Their readers report every problem at its location.
- Contexts, which say exactly which codecs, data types and other extensions a program reads.
This is not a full Zarr implementation. Nothing here reads or writes chunks, encodes or decodes data, or performs store I/O.
import json
from zarr_metadata import ZarrV3ArrayMetadata
with open("zarr.json", "rb") as f:
raw = json.load(f)
metadata = ZarrV3ArrayMetadata.from_json(raw)
from_json returns the model, or raises MetadataValidationError with
every problem it found. The
documentation has a guide for
each kind of use, and the API reference.
