 - query the data via custom index logic optimized for specific applications (e.g. an :py:class:`~xarray.Index` object backed by a KDTree structure),
 - attach domain-specific logic via accessor methods (e.g. to understand geographic Coordinate Reference System metadata),

 In this situation xarray would be essentially a thin wrapper acting as pure-python framework, providing a common interface and
 separation of concerns via various domain-agnostic abstractions.
