Abstract

Exemplary methods, devices, systems, and/or storage media for organizational data management, including staging, synchronizing, and exporting of organizational data. Exemplary data aggregation rules specify methods for aggregating data from a remote repository. Schemas are exemplary rules configuration data structures having elements for associating processing data objects in a buffer space objects in a core space. The elements may also specify importing attributes into and exporting attributes from the core space.

8. A method as recited in claim 6 wherein the schema further comprises:

9. A method as recited in claim 6 wherein the schema further comprises:

an extension element specifying an extension related to an assembly to be employed to carry out one or more of the elements in the schema.

21. A computer-readable medium as recited in claim 20, wherein the schema sub-element further specifies attributes associated with objects from the data repository.
