Thanks for writing this up @emilbiju . These are very interesting ideas

  1. The nice thing about using NetCDF groups (or HDF5?) is that it is a standard and your data files are readable using other software.

  2. So far, xarray has been reluctant to add "groups" or this kind of hierarchical organization because of all the additional complexity involved (#1092)

  3. That said, there is definitely interest in a package that provides a high-level object composed of multiple xarray datasets (again #1092). So I encourage you to post your code online so others can try it out and iterate.

    a. For example, our friends over at Arviz have a InferenceData structure composed of multiple Datasets that is represented on-disk using NetCDF groups: https://arviz-devs.github.io/arviz/notebooks/XarrayforArviZ.html
