Definition
The Business Process Execution Language for Web Services (BPEL) has emerged as a standard for specifying and executing processes. It is supported by many vendors and positioned as the “process language of the Internet.” BPEL is XML based and aims to enable “programming in the large,” i.e., using BPEL new services can be composed from other services.
Key Points
BPEL [2, 3] supports the modeling of two types of processes: executable and abstract processes. An abstract, (not executable) process is a business protocol, specifying the message exchange behavior between different parties without revealing the internal behavior for any one of them. This abstract process views the outside world from the perspective of a single organization or (composite) service. An executable processviews the world in a similar manner.
