摘要： Systems and techniques of the management of the metadata of a database are presented. A provider is in communication with a database and a set of consumers of the database. Data may be changed by addition, editing or deletion from the database and such changes are recorded and/or maintained by the provider on a list of changes. The changes on this list may be associated with a sync token. The provider may also maintain a list of consumers and associate with each consumer a last sync token which describes when the last sync request and update on the database was made with the consumer. Data which is deleted from the database is recorded with a tombstone. The tombstone is maintained on the list of changes until all consumers have been made aware of the deletion—then the tombstone may be deleted from the list of changes.

摘要： A provided computing device detects a synchronization conflict between two versions of a file and may examine corresponding metadata fields. The computing device may characterize a nature of a difference between metadata fields as immutable, mergeable, or subsumable. Core metadata fields may be defined such that a nature of a difference, or conflict, is categorized as immutable. Non-core metadata fields may be defined such that a nature of a difference, or conflict, is characterized as either mergeable or subsumable. A conflict between corresponding mergeable non-core metadata fields may be resolved by merging values of the corresponding non-core metadata fields. A conflict between corresponding subsumable non-core metadata fields may be resolved by replacing a value of a non-core metadata field of an older of the two versions of the file with a value of a corresponding non-core metadata field of a younger of the two versions of the file.

摘要翻译：介绍了数据库元数据管理的系统和技术。提供者与数据库和数据库的一组消费者进行通信。可以通过数据库的添加，编辑或删除来更改数据，并且这些更改由提供者在更改列表上记录和/或维护。此列表中的更改可能与同步令牌相关联。提供商还可以维护消费者的列表并且与每个消费者关联最后的同步令牌，其描述了数据库上的最后一个同步请求和更新是否与消费者进行的。从数据库中删除的数据以墓碑记录。在将所有消费者都知道删除之前，将墓碑保留在变更清单上，然后可能会从更改列表中删除墓碑。
