 .. note:: Lists can always be expressed in different ways. It is possible to use lists, comma separated strings or single items. These are valid lists: ``['foo', 'bar']``, ``'foo, bar'``, ``"foo", "bar"`` and ``'foo'``. Additionally, there are several ways to define a boolean value. ``True``, ``on`` and ``1`` are all vaid boolean values.
 
 .. note:: The table structure of the DataStore is explained in :ref:`db_internals`.
