  * Dataview that maps generic field names to storage specific fields or requests them via handlers.
  *
- * When accessing objects, every storage api returns them with other names. You can't simply say $object->service_state,

- * This view is intended for normalizing these changes, so a request of service_state returns the right field for the backend.
- * When implementing it, you have to fill the mappedParameters and/or the handlerParameters array. While mappedParameters
- * simply translate logic field names to storage specific ones, handlerParameters determins functions that handle data
