nczarr-c (v2)

This could likely be split between CLI tools, C, and Java implementations.

Tagging myself in on this as well. @WardF

To add a clarifying note from an internal Unidata conversation, one thing we'll need to keep in mind is that nczarr (as implemented in the netcdf C library), and the addition of zarr support in netcdf-Java, are two different projects being handled by different personnel.

[joshmoore]

Is the plan to have netcdf-Java support zarr, nczarr, or both?

[WardF]

@joshmoore Just to clarify, do you mean nczarr? Or is czar a separate thing?

[joshmoore]

Or is czar a separate thing?

Oh Jeez. I hope not!! (Corrected my typo 😉)

[haileyajohnson]

As of now, the scope of the netcdf-java implementation will only be explicitly supporting zarr (i.e. not reading ".nczarray" or ".nczattr"). We can later expand the implementation to read nczarr as well, but the primary goal is java support for reading zarr into the common data model.

Ok. Splitting this into two issues then.
