Abstract: Changes to a hierarchical organizational structure may be stored in different versions of a data structure depicting the hierarchical organizational structure. Each of these versions may include a validity period field representing a time period that the hierarchical organizational structure depicted in the version accurately reflects the organizational structure of the organization. Each of the versions may also be designated as active or inactive. In some instances, each of the versions may be designated as inactive except for a version that reflects the organizational structure of the organization at a particular time, which may change over time. Historical copies of versions may be stored and subsequently recalled to identify an organizational structure that was in effect at a particular time in the past. The recalled version may then be used to limit the results of a query to a selected node of the historical organizational structure.
