Abstract

This paper investigates the problem of dynamic reconfiguration by means of a workflow-based case

study used for discussion. We state the requirements on a system implementing the workflow and its

reconfiguration, and we describe the system’s design in BPMN. WS-BPEL, a language that would

not naturally support dynamic change, is used as a target for implementation. The WS-BPEL recovery

framework is here exploited to implement the reconfiguration using principles derived from

previous research in process algebra and two mappings from BPMN to WS-BPEL are presented, one

automatic and only mostly manual. Differences between the two are finally detailed.

Keywords: Workflow Reconfiguration, BPMN, WS-BPEL
