    摘要: Update-delete conflicts detected during synchronization can be resolved in favor of the update or the deletion. Resolving the conflict in favor of the deletion results in the entity deleted on one replica being deleted on all selected replicas. Resolving the conflict in favor of the update results in the updated entity, which includes an entity moved from one hierarchy to another, being replicated on all selected replicas. To resolve the conflict in favor of the update, the deletion is treated as though it were reported erroneously. The deleted entity is resurrected in the form of the updated entity. Change version information is maintained in all replicas. Update-delete conflicts are resolvable in accordance with various resolution policies such as the update wins, deletion wins, changes occurring on a particular device wins, and most recent event wins, for example.

    摘要: A protocol for replicating replicas in a sync community. Each replica maintains a knowledge that represents changes that the replica is aware of. Each replica does not typically maintain knowledge about other replicas. The protocol includes messages that include knowledge about changes on the various replicas. Using the knowledge, the replicas can enumerate changes and send the changes using asynchronous messages that do not need to be received in any particular order. The protocol enables filters to ensure that a valid replication is possible using a minimum knowledge argument. The protocol also enables replicas to partially replicate using filtered knowledge.

    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: Tombstones can be removed from a data store without data corruption. Tombstones placed into a forgotten knowledge list can be compared against each other and/or items in a tombstone table, and deleted when tombstones representing subsequently deleted items are extant. Also, creation database version information can be kept along with database items, and databases can record database version information when they synchronize. If a synchronizing database discovers an item that it does not have, but the creation database version information associated with the item reflects that the synchronizing database “should” have the item, then it can be inferred that the item was subsequently deleted, and item resurrection can be prevented.

    摘要: A uniform data structure contains a number of data fields. Some of the data fields are dedicated to contain information concerning the transfer of a data segment of a particular type (such as an XML segment) using one particular transfer mechanism (such as transferring as a string or DOM object, or transfer using an interface such as ISAXContentHandler, ITextSource, ITextSink, or IDOMSink interfaces). Other data fields are dedicated to contain information concerning the transfer of data segments of the same particular type using another transfer mechanism. When a module is to transfer a data segment, the module will cause the unified data structure to be altered as appropriate for the desired transfer mechanism.
