Abstract: In some embodiments, a system for synchronizing content with client devices receives a request from a client device to synchronize operations pertaining to content items associated with a user account registered at the system. The request can include the operations and a cursor identifying a current position of the client in a journal of revisions on the system. Based on the operations, the system generates linearized operations associated with the content items. The linearized operations can include a respective operation derived for each of the content items from one or more of the operations.
