Patent ID: 7403878

Claim:
A method of preparing a graph-oriented process meta model in a first workflow management system (WFMS) for translation to a second workflow management system (WFMS): providing a graph-oriented process meta model on a computer-readable medium, the model comprising: a plurality of activity nodes, wherein each activity node represents an activity; at least one control connector, wherein each control connector represents a potential sequence of execution of the activities; and at least one sphere, wherein each sphere represents a subset of the plurality of activities that are a sub-graph of the model; changing the graph-oriented process meta model by representing a location of the sphere by adding sphere nodes according to a set of rules comprising: placing a begin sphere node where an edge enters the sphere; placing an end sphere node where an edge leaves the sphere; placing a begin sphere node when an activity within the sphere has no edge leading to it; and placing an end sphere node when an activity within a sphere has no edge leaving it; and providing the changed graph-oriented process meta model on a computer-readable medium, wherein the meta model only uses activities and connectors.
