Another example of encoding vs. data model:

An array of integers is a data model

The binary representation of that array is encoding: is it big or
little endian, for instance.

Netcdf already abstracts that out for you -- your code does not need
to care. I think this principle could be extended to higher-lever
abstractions like datetimes, and encodings like integer*scale+offset
