re: https://github.com/zarr-developers/zarr-specs/issues/41 After discussions with the Zarr community, it was decided to convert to a new representation of the NCZarr meta-data extensions: version 2. These extensions store information necessary to mapping the Zarr data model to the netcdf-4 data model. The basic change is to remove the NCZarr specific objects: .nczarr, .nczgroup, .nczarray, and .nczattr. The contents of these objects is moved into the corresponding existing Zarr objects as special keys. The mapping is as follows: * ''.nczarr'' => ''/.zgroup/_NCZARR_SUPERBLOCK_'' * ''.nczgroup => ''.zgroup/_NCZARR_GROUP_'' * ''.nczarray => ''.zarray/_NCZARR_ARRAY_'' * ''.nczattr => ''.zattr/_NCZARR_ATTR_'' Backward compatibility is maintained by looking for the object ''/.nczarr'' and if found, then assuming that the dataset is in the older version 1 format. This compatibility only supports reading of such version 1 datasets. Documentation and test cases are also added. Misc. Other Changes: 1. The json parsing code was added to the general library instead of nczarr only (ncjson.c, ncjson.h). 2. Improved support for different platform paths by allowing conversion to a single common path representation. 3. Add some new error codes. 4. Modify nccopy usage to mention the new chunking specification.
