1197041777 PR_kwDOAMm_X85HWWhx 7437 open 0 DRAFT: Implement `open_datatree` in BackendEntrypoint for preliminary DataTree support 3460034 <!-- Feel free to remove check-list items aren't relevant to your change --> As discussed among folks at today's Pangeo working meeting (cc @jhamman, @TomNicholas), we are looking to try adding support for `DataTree` in the Backend API, so that backend engines can readily add `DataTree` capability. For example, with `cfgrib`, we could have ```python import xarray as xr dt = xr.open_datatree("path/to/gribfile.grib", engine="cfgrib") ``` given that `cfgrib` implements the appropriate method to their `BackendEntrypoint` subclass. Similarly, with NetCDF files or Zarr stores with groups, we could open as `DataTree` to obviate the need to specify a single group.
