摘要： Various embodiments of the present invention are directed to systems and methods for synchronizing mixed elements (MEs) comprising structure data and unstructured filestreams between peer computer systems in a hardware/software interface system environment that does not permit snapshotting of large unstructured ME filestreams during synchronization. For several such embodiments, the method comprises synchronizing the ME in two steps, one for snapshotting the structured data component of the ME (as well as the cv of the filestream but not the filestream itself) and one for locking and transmitting the filestream to the receiving sync peer if and only if, after being locked, it is determined that the filestream is unchanged from the time of the ME data component snapshot.

摘要： A system and method for synchronizing a database comprising raw data and metadata derived from the raw data, but when the metadata has not yet been updated. The raw data and the metadata are first synchronized, with the raw data having been assigned a version number. After synchronization, any stale metadata will be updated and assigned the same version number as the raw data.

摘要： Several embodiments of the present invention employ synchronization adapters for synchronizing information between “WinFS” and non-“WinFS” data sources. Examples of adapters include an adapter that synchronizes address book information between a “WinFS” contacts folder and a non-WinFS mailbox. In these instances, adapter developers might use the “WinFS” synchronization core services API described herein for accessing services provided by the “WinFS” synchronization platform in order to develop schema transformation code between the “WinFS” schema and the non-“WinFS” data source schema. Additionally, the adapter developer provides protocol support for communicating changes with the non-“WinFS” data source. A synchronization adapter is invoked and controlled by using the synchronization controller API and reports progress and errors using this API.
摘要翻译：本发明的几个实施例使用同步适配器来同步“WinFS”和非“WinFS”数据源之间的信息。适配器的示例包括在“WinFS”联系人文件夹和非WinFS邮箱之间同步地址簿信息的适配器。在这些情况下，适配器开发人员可能会使用本文所述的“WinFS”同步核心服务API来访问由“WinFS”同步平台提供的服务，以便在“WinFS”模式和非“WinFS”数据之间开发模式转换代码源模式。此外，适配器开发人员提供了与非“WinFS”数据源进行更改通信的协议支持。使用同步控制器API调用和控制同步适配器，并使用此API报告进度和错误。

摘要： Various embodiments of the present invention are directed to conflict handling for conflicts that occur in a peer-to-peer synchronization system, where the ability to correctly and efficiently handle conflicts minimizes data loss while retaining good usability and reduces the need for user intervention during synchronization. Conflict handling in the synchronization service is divided into three stages: (1) conflict detection; (2) automatic conflict resolution and logging; and (3) conflict inspection and resolution. Certain embodiments are directed to a conflict handling schema comprising one or more of the follow conflict handling elements: (a) schematized representation of conflicts; (b) detection of conflicts; (c) logging of conflicts into a durable store; (d) automatic resolution of conflicts according to a flexible and configurable azqsxqxwdconflict resolution policy; (e) composable and extensible conflict handlers to filter and resolve conflicts; (f) automatic detection and removal of obsolete conflicts; and (g) programmatic conflict resolutions.

摘要： Various embodiments of the present invention are directed to systems and method for detecting conflicts and applying conflict resolutions during manual and automatic conflict resolution operations. Several embodiments are directed to preventing both: (a) non-convergence of conflict resolutions, where partners can end up in a divergent steady state (i.e. have different data in the absence of outstanding conflicts); and (b) a non-terminating ping-pong of conflict resolutions between partners (which can occur with certain inefficient solutions that continuously update metadata for each conflict resolution without end). Certain specific embodiments of the present invention are directed to a method for maintaining knowledge that guarantees convergence of data, even when different partners apply different conflict resolutions.

摘要： A system and method for synchronizing a database having metadata and raw data. Metadata may be fully synchronized between two systems, with copies stored on both systems. Raw data may be selectively synchronized, so that a client system need not store all of the raw data locally. When disconnected, the client system may identify certain portions of the raw data to store locally, and such data may be synchronized when reconnected to a server system.

摘要： The subject invention pertains to data synchronization across replicas. Disclosed are systems and methods of detecting and handling constraint-based conflicts that occur during a synchronization session. In accordance with one particular aspect of the invention, name-constraint violations can be detected. These violations can be resolved by generating a single merged identity that can be utilized to refer to data units, for example on different replicas that had the same name. A property of the merged identity can be merge history, which specifies the identifiers subsumed by the merge.

摘要： Systems and methods for replicating replicas in a sync community. Each replica in the sync community stores knowledge that represents changes the replica is aware of. Because each replica has its own knowledge, each replica does not need to know how many replicas are in the sync community or the topology of the sync community. By sending the knowledge with a request for changes, a replicating replica can enumerate the changes to replicate by comparing its knowledge with the received knowledge. After replication, the knowledge is updated. Knowledge may also include made-with-knowledge change IDs that permit each resolution to identify what a replica was aware of when a particular change was made. The made-with-knowledge values are used to detect conflicts during replication.
摘要翻译：在同步社区中复制副本的系统和方法。同步社区中的每个副本都存储表示副本所注意到的更改的知识。由于每个副本都有自己的知识，因此每个副本不需要知道同步社区中多少副本或同步社区的拓扑。通过向知识发送更改请求，复制副本可以通过将其知识与接收到的知识进行比较来枚举复制的更改。复制后，知识将被更新。知识也可以包括知识变更ID，允许每个决议识别在进行特定更改时复制品知道什么。使用知识产权值用于检测复制期间的冲突。
