BPEL4Chor

Choreography Extension for BPEL

BPEL4Chor offers means to describe choreographies using WS-BPEL 2.0. BPEL4Chor uses the idea of plug-links of WSFL and adds the explicit modelling of participant sets and participant references.

Modeling BPEL4Chor

We developed a web-based editor for BPEL4Chor choreographies using the Oryx-Framework developed by the Hasso-Plattner-Institute.

The editor is currently not running.

Verification of BPEL4Chor

BPEL4Chor can be analysed using BPEL2oWFN developed by Dr. Niels Lohmann.
