Abstract

A computerized method for automatically transforming the process model of a workflow-management-system into trigger-specifications executable within a trigger system. The process model comprises at least one source activity S, a target activity T and a control connector defining a potential control flow from said source activity to said target activity associated with a transition condition P. The source activity S is transformed into a trigger event. The trigger-event, if raised at run-time, indicates to said trigger system that an instance of said source activity has been terminated. The control connector is transformed into a trigger condition, causing said trigger system at run-time, once said trigger event has been raised, to evaluate the truth value of said transition condition. Furthermore said target activity is transformed into a trigger action causing said trigger system at run-time, in case said trigger condition evaluates to TRUE, to start an instance of said target activity.
