The XArray implementation that uses Zarr for storage provides a mechanism to simulate named dimensions. It does this by adding a per-variable attribute called _ARRAY_DIMENSIONS. This attribute contains a list of names to be matched against the shape values of the variable. In effect a named dimension is created with the name _ARRAY_DIMENSIONS(i) and length shape(i) for all i in range 0..rank(variable). Both read and write support is provided. This XArray support is only invoked if the mode value of "xarray" is defined. So for example, as in this URL. ```` https://s3.us-west-1.amazonaws.com/bucket/dataset#mode=nczarr,xarray,s3 ```` Note that the "xarray" mode flag also implies mode flag "zarr", so the above is equivalent to this URL. ```` https://s3.us-west-1.amazonaws.com/bucket/dataset#mode=nczarr,zarr,xarray,s3 ```` The primary change to implement this was to unify the handling of dimension references in libnczarr/zsync. A test for this and other pure-zarr features was added as nczarr_test/run_purezarr.sh Other changes: * Make sure distcheck leaves no files around. * Change the special attribute flag DIMSCALEFLAG to HIDDENATTRFLAG to support the xarray attribute. * Annotate the zmap implementations with feature flags such as WRITEONCE (for zip files). |
