Abstract: A remote distributed data store may be configured to process data updates received through invocation of a common API with reference to a common schema. A local data store may also be configured to process updates through the common API with reference to the common schema. Updates to the local data store may be mapped from the local data store schema to the common schema, and applied to the distributed data store. Updates to the distributed data store may be mapped from the common schema to the local data store schema. User identity may be verified to limit data synchronization to authorized users.

Abstract: A trailer coupling for a motor vehicle includes a base holder which can be or is securely mounted on the vehicle and further includes a coupling arm at the free end of which a coupling element is arranged for coupling a trailer and which protrudes towards the rear from the motor vehicle in a position of use, wherein the coupling arm can be releasably secured to the base holder or is mounted movably between the position of use and a position of non-use in which it is moved towards the motor vehicle. In the trailer coupling, it is provided that, for connection to the base holder, the coupling arm includes a holder part which can be secured to the base holder by means of a base holder fixing device and a coupling part on which the coupling element is located.
