Abstract
A system that persistently maintains and exposes one or more previous object hierarchies to which an object belonged across one or more hierarchy destroying operations, such as operations that delete parent objects, add parent objects subsequent to addition of their descendent objects, forward objects to or from the hierarchy, and/or modify hierarchy determining rules. A user interface object allows user access to one or more persistent hierarchies for the corresponding object. A hierarchy list or the like allows a user to select a desired one of the persistent hierarchies. A persistent hierarchy can be accessed in the disclosed system through a display object associated with any object within the hierarchy, including the root, leaves, and any intervening objects. When objects are deleted, “ghost” objects are maintained and displayed to the user in the hierarchical positions of the deleted objects when a persistent hierarchy is displayed.
