<p>FYI, the driver has now been merged into GDAL master and Docker
images have been regenerated (use the ubuntu-full or alpine-normal
ones to get support for all compression codecs supported by the
driver)<br>

<p>Hi all,</p>
<p>for those who have monitored the PR tracker lately, you may
have noticed that I've been working in <a

moz-do-not-send="true">https://github.com/OSGeo/gdal/pull/3896</a>
for an implementation of a Zarr driver. This is now feature
complete and in a CI ready state. It follows a different
approach than the one proposed in PR #3411 for the reasons I
underlined in <a class="moz-txt-link-freetext"

<div>Hi all,</div>
<div><br>
</div>
<div>Also deep in our recent long thread about removing
drivers from GDAL is mention of a new PR for a "zarr"
driver.</div>
<div><br>
</div>
<div><a href="https://github.com/OSGeo/gdal/pull/3411"
target="_blank" moz-do-not-send="true">https://github.com/OSGeo/gdal/pull/3411</a></div>
<div><br>
</div>
<div>I'd like to see more discussion of the scope of this work
and plans for future development and support before a zarr
driver is added to GDAL.</div>
<div><br>
</div>
<div>Is the zarr driver not going to support version 2 of the
zarr spec? I that v2 would be difficult to implement as a
GDAL driver as it is extremely flexible and extensible. For
example, I've written custom compressor and storage for use
in a project at work and can't imagine how a driver written
in C++ would understand it.</div>
<div><br>
</div>
<div>Is the zarr driver based on <a
href="https://zarr-specs.readthedocs.io/en/core-protocol-v3.0-dev/protocol/core/v3.0.html"
moz-do-not-send="true">https://zarr-specs.readthedocs.io/en/core-protocol-v3.0-dev/protocol/core/v3.0.html</a>?
That work seems not yet finished. Is it premature to add a
driver to GDAL for a format that isn't yet specified and may
yet be changed? Or should we expect only minor changes at
this point?<br>
