"""Domain model for data :term:`acquisition`.
:class:`Resource` is the base class for the plugin's :term:`domain
model`. It shoul model the relevant details of reality that a plugin is
supposed to check. The :class:`~.check.Check` controller calls
:meth:`Resource.probe` on all passed resource objects to acquire data.
Plugin authors should subclass :class:`Resource` and write
whatever methods are needed to get the interesting bits of information.
The most important resource subclass should be named after the plugin
itself.
