Definition

Business Process Execution Language (BPEL), short for Web Services Business Process Execution Language (WS-BPEL) is an executable language for specifying interactions with Web Services. (Wikipedia)

“Web service interactions can be described in two ways. Executable business processes model actual behavior of a participant in a business interaction. Abstract business processes are partially specified processes that are not intended to be executed. An Abstract Process may hide some of the required concrete operational details. Abstract Processes serve a descriptive role, with more than one possible use case, including observable behavior and process template. WS-BPEL is meant to be used to model the behavior of both Executable and Abstract Processes.(Business Process Execution Language, retrieved jan 5 2009).”

Tools

Visual design tools

• BPMN (not tested) is an example

BPEL applied to e-science

• OMII-BPEL, OMII-BPEL brings an industrial standard, BPEL (Business Process Execution Language) to scientific workflow modeling and Grid services orchestration.

In education

Karampiperis and Sampson argued that BPEL (or rather a graphical representation language) could be used to design learning designs/ pedagogical scenarios that then can be compiled into IMS Learning Design Level A Representations.
