ABSTRACT
A real-time data object, for example, the speed or position of a vehicle, or the temperature in an engine, is temporally consistent if its value reflects the current status of the corresponding entity in the environment. This is usually achieved by associating the value with a temporal validity interval [3,4,6-8,11-14,17-19]. For example, if position or velocity changes that can occur in 10 s do not affect any decisions made about the navigation of a vehicle, then the temporal consistency interval associated with these data elements is 10 s.
