摘要：An “Eventually Consistent Sharing Model” provides various techniques for

using “revision diagrams” to determine both arbitration and visibility of changes orupdates to shared data (e.g., data, databases, lists, etc.) without requiring a causallyconsistent partial order for visibility, and without requiring change or update timestampsfor arbitration. In particular, the Eventually Consistent Sharing Model provides fork-joinautomata based on revision diagrams to track the forking and joining of data versions,thereby tracking updates made to replicas of that data by one or more sources. “Cloudtypes” are used to define a structure of the shared data that enables fully automaticconflict resolution when updating the shared data. These concepts enable mobile devices(or other computing devices that may periodically go “offline”) to share structureddata in cloud-based environments in a manner that provides local data replicas for offlineoperation while guaranteeing eventually consistent convergence of the data replicas.
