    Abstract: The present discloses a framework that allows a synchronization engine to synchronize data between a mobile device and Back End data stores independently from the architecture and data formats of that Back End data store. The framework introduces content adapters, which access synchronization data from backend data systems. These adapters convert the data into a Back End data store independent representation, which can be used by all applications or modules which need to access different back-ends in a generic manner. A generic synchronization engine for the purpose of conflict detection and resolution is one example for a module of this kind. Other applications that could use the content adapter are Notification Frameworks or Portals and all other applications aggregating data.

    Abstract: The present invention discloses a new synchronization architecture for synchronization of data between different clients by using a central synchronization server linked to a Back End data store which additionally provides a cache for permanently buffering incoming updates into a permanent store by assigning an unique cache identifier (ID). Write conflicts between the synchronization server writing new entries to the cache and updates replicated from backend to cache are solved using a blocking mechanism based on the cache IDs, so that the backend updates are blocked as long as incoming updates from the clients having the same cache ID are not completely written into the cache during a synchronization session. The present invention is preferably suited for a synchronization architecture having a high number of clients connected with the central synchronization server as blocking of the Back End data store, and the connection and the transport to the Back End data store are minimized.

    Abstract: The present invention relates to a method for providing an interoperable digital rights management system for content data on a client based on synchronization technology, the method comprising the steps of: - receiving of a selection of content data from the, client, - generating of an XML file having a defined DTD format, the XML file comprising license information and a locator for the content data, - sending of the XML file to the client, synchronizing any license status relates data produced on the client back to the server.
