Business Process Execution Language (BPEL)


  • An XML based business process modelling language which aims to enable interoperable ‘programming in the large’ for high-level state transition interactions
  • A standard maintained by OASIS
  • Originates from WSFL (IBM) and XLANG (Microsoft)
  • Specifies conditional behaviour to send messages, wait for messages, compensate for failed transactions, sequential/parallel, synchronous/asynchronous processing etc.

Two types of process:

  • Executable - models the actual behaviour of the participants in a business interaction
  • Abstract - partially specified processes not intended to be executed
