Add to ORKGA method of adding time to active databases is described in this paper. This is achieved by incorporating operators of temporal logic, temporal actions, and different temporal clauses into the Event-Condition-Action model of a rule. In addition, a temporal recognize-act cycle is described and new temporal conflict resolution strategies are proposed. A conflict avoidance strategy for temporal rules is also described.Information Systems Working Papers Serie
