This would already be quite cool! But would the mechanism allow to pass arguments to the MyLibGis class at construction time? This might also be wordy, maybe something like ds = xray.DataArray(data, gis={'arg1':42})?

My suggested approach here would be to simply write functions instead, e.g.,

def make_gis_array(data, gis=None): data = xr.DataArray(data) data.attrs['gis'] = gis # or whatever

This is similar to how I would suggest inserting lazy variables, i.e., write your own functions using dask.array:

def add_lazy_vars(data): if 'P' in data and 'PB' in data: data['TP'] = data['P'].chunk() + data['PB'].chunk() return data
