Embodiments provide systems, methods, and computer program products for tracking objects within a domain and their possible changes and genealogy over time. An object identifier and an interval identifier are associated with an object that enters the domain with an unknown set of attributes and genealogy. The object identifier is analyzed to determine whether it is a pre-existing object identifier. A comparison of the interval identifier is performed to determine whether the object is a copy of a prior object. The object identifier is replaced with a new object identifier and the interval identifier reset when the object is new or a copy. Based on the object identifier and the interval identifier, which represents the possibility of change during each interval, information about the tracked object may be derived and analyzed to enhance performance.
