Save to Fedora any parts of this object that have been
        modified (including object profile attributes such as
        :attr:`label`, :attr:`owner`, or :attr:`state`, and any
        changes to datastream content or datastream properties).  If a
        failure occurs at any point on saving any of the parts of the
        object, will back out any changes that have been made and
        raise a :class:`DigitalObjectSaveFailure` with information
        about where the failure occurred and whether or not it was
        recoverable.

        If the object is new, ingest it. If object profile information has
        been modified before saving, this data is used in the ingest.
        Datastreams are initialized to sensible defaults: XML objects are
        created using their default constructor, and RDF graphs start
        empty. If they're updated before saving then those updates are
        included in the initial version. Datastream profile information is
        initialized from defaults specified in the :class:`Datastream`
        declaration, though it too can be overridden prior to the initial
        save.
