Modeling UML activity diagrams with aspect oriented data concerned Petri nets

To enhance formal analysis ability, UML activity diagrams are transformed into Petri nets. Elements in an activity diagram are formally defined for formal mapping rules definition. To model activity diagrams, data concerned Petri net (DCPN) is proposed. Data related issues in an activity diagram can be handled with the help of DCPN. Mapping rules from elements of an activity diagram to DCPNs are proposed both in graphical and formal forms. The soundness of each mapping rule is analyzed based on semantic equivalence relation. Aspect oriented techniques are used to compose DCPNs automatically. This paper provides foundation for developing model transformation tools from UML diagrams to analyzable Petri nets.
