Subprojects

Alongside zarr itself, the zarr-python repository hosts a small number of companion packages. Each one is developed in the same repository but versioned, released, and documented independently, so you can depend on it without taking on zarr as a dependency.

• :material-code-json:{ .lg .middle } zarr-metadata

  ---

  Spec-defined metadata types, models, and validators for Zarr v2 and v3, with minimal dependencies. Useful if your software reads or writes Zarr metadata documents but does not need a full Zarr implementation.

  pip install zarr-metadata

• :material-vector-polyline:{ .lg .middle } zarr-indexing

  ---

  Composable, lazy coordinate transforms for Zarr array indexing. Makes the mapping from requested coordinates to stored coordinates a first-class, composable value, and resolves which chunks a selection touches.

  pip install zarr-indexing

• :material-server:{ .lg .middle } zarr-http-server

  ---

  HTTP server for Zarr stores, arrays, and groups.

  pip install zarr-http-server

• :material-key:{ .lg .middle } zarr-chunk-key-encoding

  ---

  Chunk key encodings for Zarr v3 arrays: the spec-defined default and v2 encodings, grid-bounded encodings with finite key sets, and strict decoding of a store key back to a chunk grid index.

  pip install zarr-chunk-key-encoding
