1. Introduction The idea of subscriptions is becoming more and more popular with the users of computer systems, in particular, with the increasing amount of information available. Users must no longer periodically query for new information. The appropriate computer systems offer the user the capability to subscribe to the system and specify upon which event they would like to be notified. Workflow management systems  manage the execution of business processes. Those business processes are modeled as graphs. The major constructs in drawing processes are activities and control connectors. The activities describe the tasks to be performed, and the control connectors describe the potential sequence in which the activities are to be carried out. Figure 1 shows schematically the structure of such a process graph.
