The Business Process Execution Language (BPEL)
is a language to orchestrate web services into a single
business process. In a choreography view, several processes
are interconnected and their interaction behavior
is described from a global perspective. This paper shows
how BPEL can be extended for defining choreographies.
The proposed extensions (BPEL4Chor) distinguish between
three aspects: (i) participant behavior descriptions,
i.e. control flow dependencies in each participant,
(ii) the participant topology, i.e. the existing participants
and their interconnection using message links and (iii)
participant groundings, i.e. concrete configurations for
data formats and port types. As BPEL itself is used unchanged,
the extensions facilitate a seamless integration
between service choreographies and orchestrations. The
suitability of the extensions is validated by assessing
their support for the Service Interaction Patterns.
