* {@link DeviceIdentifier} objects need to be stored in the database, e.g., for
* {@link RaceLog} persistence, when writing an object of type
* {@link DeviceCompetitorMappingEvent}. In conjunction with a
* {@link TypeBasedServiceFinder} it is possible to extend the set of device
* types whose device identifiers can be stored to and loaded from the database
* by providing specific implementations of this handler interface. In an OSGi
* context, bundles can register implementations of this handler interface with
* the OSGi service registry to extend the set of supported device types without
* modifications to the existing code base.
*
* The resulting {@link Object} is expected to be either a simple {@link Object}
* that can serialized, or a structured {@link DBObject}.
