Business processes -- expressed in the Web Service Business Process
Execution Language (WS-BPEL or BPEL for short) -- are a
manifestation of the two-level-programming paradigm where
individual, remote-accessible Web services are composed to
potentially complex orchestrations. BPEL processes are executed by
so-called Workflow Management Systems that navigate through the
process' activities according to the order imposed by the
process model and interact with the services orchestrated by the
process. While Web service technology enables interactions with
remote services, process navigation is done in a centralized manner.
Especially in scenarios of complex interactions between multiple
distributed process participants, this way of enacting process
models has several drawbacks. In the paper, we outline those
drawbacks and propose an alternative approach to execution of BPEL
processes in a distributed, decentralized manner. We present an
overview of the system model and architecture and describe how the
proposed approach enables a broad spectrum of process distribution.
