Abstract

A method and system for tracking, and resolving links to, objects that derive from a common object creation is provided. In a system, the system creates a source object. The system then generates a lineage identifier to identify the creation of the source object. Then the system associates the lineage identifier with the source object. At a later time, the system copies the created object to a copy object. When the source object is copied to a copy object, the system associates the lineage identifier associated with the source object with the copy object. In this way, the lineage identifier associated with the copy object indicates that the copy object derives from the creation of the source object. The system links a client object to a source object by storing a link containing the source object's lineage identifier in the client object. A link also contains information for distinguishing the source object from other objects having the same lineage identifier. When resolving the link to the source object, the system selects the lineage identifier and the distinguishing information contained in the link. The system then searches for an object with the selected lineage identifier and distinguishing information. When an object with the selected lineage identifier and distinguishing information is found, the system resolves the link to the found object. When an object with the selected lineage identifier and distinguishing information is not found, the system searches for an object with the selected lineage identifier without regard to the selected distinguishing information. When an object with the selected lineage identifier is found, the system resolves the link to this found object.
