The Business Process Modeling Notation (BPMN) is a graph-oriented modeling language which is becoming increasing popular in recent years. On the other hand, the Business Process Execution Language for Web Services (BPEL) is a block- structured language which is mainly used in formal Description of Business Process.

It effectively addresses the above requirements.
