This project is part of the GNU Project.

BPEL2oWFN translates a web service expressed in BPEL (Business Process Execution Language for Web Services) into an oWFN (open Workflow Net). This oWFN can be used to:

BPEL2oWFN uses static analysis to make the generated oWFN as compact as possible to analyze a chosen property. This is called flexible model generation.

BPEL2oWFN is the successor of BPEL2PN, a Java-based compiler generating low-level Petri nets. BPEL2oWFN is a re-implementation for extensibility and performance issues. Its functionality is a superset of the functionality of BPEL2PN.

GNU BPEL2oWFN was written by Niels Lohmann, Christian Gierds and Martin Znamirowski. It is part of the Tools4BPEL project funded by the Bundesministerium für Bildung und Forschung.

Development Status
: 5 - Production/Stable

Details (job description, contact ...):

The translation from BPEL to Petri nets is very complex, as each BPEL construct can be mapped by various Petri net patterns. The validation of the compiler is getting harder and harder, and we often experience regression bugs.

We need someone who can create test benches and a regression tests. The tests should be integrated in our Automake/Autoconf framework. Addition or modification of test cases should be easy.

For questions, please contact Niels Lohmann (
