WS-BPEL 2.0 Extensions for Sub-Processes

Designing complex and large business processes requires a language that supports modularization and re-use, in a portable, interoperable way. This paper outlines an extension to WS-BPEL that allows for the definition of sub-processes that can be reused within the same or across multiple WS-BPEL processes. The paper describes different invocation scenarios and introduces an appropriate coordination protocol used for interoperable invocation of sub-processes across infrastructures from different vendors.
