FeedSync is an RSS and Atom extension specification designed to synchronize changing information from multiple sources.
Extensions add data on the relevance and status of information, status (appearance, change, deletion), conflicts, associations and history of changes in information. The specification also describes the rules for the behavior of format data for all the events described above. Thus, based on FeedSync, it becomes possible to create synchronization mechanisms with consistent information, that is, distributed systems.
Example
