This application discloses a device state synchronization method. The method performed by a common capability component, the method includes: receiving a first representation state instance resource creation request sent by an application, where the first representation state instance resource creation request includes a device state attribute; creating a first representation state instance resource based on the first representation state instance resource creation request and a created second representation state instance resource; sending a device state update request to a device, where the device state update request includes the device state attribute; receiving an actual state instance resource creation request sent by the device; creating an actual state instance resource based on the actual state instance resource creation request; and sending to the application, information indicating that an actual state resource is successfully created.

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. The system converts each respective operation in the linearized operations to a respective revision for the journal of revisions and, based on the cursor, determines whether the respective revision conflicts with revisions in the journal. When the respective revision does not conflict with revisions in the journal, the system adds the respective revision to the journal.

Example systems and methods for cloning catalog objects are described. In one implementation, a method identifies an original catalog object associated with data and creates a duplicate copy of the original catalog object without copying the data itself. The method allows access to the data using the duplicate catalog object and supports modifying the data associated with the original catalog object independently of the duplicate catalog object. The duplicate catalog object can be deleted upon completion of modifying the data associated with the original catalog object.
