Abstract
Process management systems reveal the full potential of Service Oriented Architectures by composing heterogeneous hardware and software components (exposed as services) to powerful distributed applications. For Web services architectures, the Web services business process execution language (WS-BPEL) is the standard for centralized Web service orchestration which is governed by OASIS. Unfortunately, WS-BPEL is quite static and addresses dynamically changing environments insufficiently as devices and services might change their addresses or be replaced by others. This paper presents extensions to WS-BPEL in order to discover devices and services as introduced by WS-Discovery. It also describes a discovery service for WS-BPEL processors not supporting presented extensions.
