Abstract: Updates to a hierarchical data structure may be selectively replicated to other replicas of the hierarchical data structure. An update for a hierarchical data structure may be received and committed to the hierarchical data structure. A determination as to whether any other replicas of the hierarchical data structure have permission to receive the update may be made. For those replicas of the hierarchical data structure with permission to receive the update, the update may be provided to the replicas and committed to the replicas. Different types of replication techniques may be implemented, such as pull-based replication techniques or push-based replication techniques. Replication permissions for objects of the hierarchical data structure may be individually defined, in some embodiments.

Abstract: A schema for a hierarchical data structure may include application specific extensions to the schema applied to a hierarchical data structure. Class may be added to the schema by individual applications granted access to a hierarchical data structure. When an access request for an object of the hierarchical data structure is received, the class may be identified in the schema and applied to process the access request to the object. Different classes may be added by different applications without disrupting the utilization of the schema for accessing the hierarchical data structure of other applications.
