摘要： A cloud computing system can be used to facilitate data item sharing and collaboration among groups of users through the creation and management of collections. A group of users, each of which is associated with at least one client device, can subscribe to a collection. A subscribed user can create a data item locally on a client device and assign the data item to a collection. In response to the assignment, each user subscribed to the collection can receive and store a copy of the data item locally on a client device. Any modifications made to a local copy of the data item can automatically be distributed to each subscribed user's client device. The modifications, including conflicting modifications, can be merged into the local copy.

摘要： Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for data synchronization. In general, one aspect of the subject matter described in this specification can be embodied in methods that include the actions of receiving a knowledge vector from a first device of the pair of devices, the knowledge vector identifying data items and latest changes to the data items known to the peer device; comparing, at a second device of the pair of devices, the received knowledge vector with a local knowledge vector for changes unknown to the first device; and sending a list of changes to the first device.
