[gdal-dev] Zarr syntax question

Hello, I'm trying to connect to this zarr:

https://ncsa.osn.xsede.org/Pangeo/pangeo-forge/gpcp-feedstock/gpcp.zarr

I can get this sort of hull description with mdim, but only "cannot find
group" with gdalinfo.

gdalmdiminfo ZARR:"
https://ncsa.osn.xsede.org/Pangeo/pangeo-forge/gpcp-feedstock/gpcp.zarr"
{
  "type": "group",
  "driver": "Zarr",
  "name": "/"
}


gdalinfo ZARR:"
https://ncsa.osn.xsede.org/Pangeo/pangeo-forge/gpcp-feedstock/gpcp.zarr"
ERROR 1: Cannot find group ncsa.osn.xsede.org

That group error makes me think there's a kind of nested dataset issue to
navigate?  But I can't see how zarr or gdal would expose those?   There is
a variable called 'precip'.

I'm comparing to the python in this notebook, which works fine on the same
system. I'm using GDAL built from source.

Cheers, Mike
