@abc.abstractmethod<EOL><INDENT>def is_enabled(self):<DEDENT>
return<EOL>
Tests if this operable is administravely enabled.

        Administratively enabling overrides any applied ``OsidEnabler``.
        If this method returns ``true`` then ``is_disabled()`` must
        return ``false``.

        :return: ``true`` if this operable is enabled, ``false`` if the active status is determined by other rules
        :rtype: ``boolean``
