r311 vs zarr-python
A side-by-side editorial comparison of r311 and zarr-python — release velocity, themes, recent moves, and the top alternatives to consider.
r311 vs zarr-python: at a glance
What is r311?
r311 curates a catalogue of Open311 endpoints and now marks the dead ones explicitly.
r311 wraps Open311 civic-issue APIs behind one R interface, with a bundled list of municipal endpoints. Recent releases are dominated by keeping that list current — Helsinki added in 0.4.4, Espoo and Oulu in 0.4.3, with Ottawa, Siegburg, Northfield and Annaberg-Buchholz deprecated. Version 0.4.3 added the machinery to record that decay: questioned and deprecated keys that make o311_api() warn or abort.
What is zarr-python?
Zarr's monorepo split keeps spinning out standalone packages, each with its own release cadence.
Zarr-python has decomposed into independently versioned packages — zarr-metadata, zarr-indexing, zarr-http-server — each shipping on its own clock inside one repository. The http server was the point where the split stopped being a refactor and produced a capability Zarr did not have. The most recent releases are the boring half of that work: docs builds, changelog tooling, and type-alias widening that only matters to downstream annotators.

r311
0.0DEVOPS
r311 curates a catalogue of Open311 endpoints and now marks the dead ones explicitly.
◆ Current state
r311 wraps Open311 civic-issue APIs behind one R interface, with a bundled list of municipal endpoints. Recent releases are dominated by keeping that list current — Helsinki added in 0.4.4, Espoo and Oulu in 0.4.3, with Ottawa, Siegburg, Northfield and Annaberg-Buchholz deprecated. Version 0.4.3 added the machinery to record that decay: questioned and deprecated keys that make o311_api() warn or abort.
◆ Where it's heading
The package's real work is curation, and it has started treating endpoint rot as a first-class state rather than letting requests fail silently. Error handling and condition objects were hardened in the same release, which fits a client whose dominant failure mode is a city's server going away. Releases are small and roughly annual.
◆ Prediction
Expect the next release to be another catalogue pass — a city or two added, more moved to questioned or deprecated — rather than new API surface.
zarr-python
6.3DEVOPS
Zarr's monorepo split keeps spinning out standalone packages, each with its own release cadence.
◆ Current state
Zarr-python has decomposed into independently versioned packages — zarr-metadata, zarr-indexing, zarr-http-server — each shipping on its own clock inside one repository. The http server was the point where the split stopped being a refactor and produced a capability Zarr did not have. The most recent releases are the boring half of that work: docs builds, changelog tooling, and type-alias widening that only matters to downstream annotators.
◆ Where it's heading
The split is being taken seriously as a distribution decision, not just a directory layout: each package gets its own docs site, its own towncrier changelog, and its own release notes discipline. That implies more packages will follow, and that the core zarr-python distribution is heading toward being a thin composition over them. Type-level changes in zarr-metadata are already being versioned as minor releases because they change what consumers can annotate against.
◆ Prediction
Expect further subpackages carved out of zarr-python along the same pattern, and zarr-indexing's LazyArray to gain the transform surface that TensorStore already exposes. A 3.2.0 final following the rc is the other open thread.
