• it´s the graphic construction of business processes

• the graphical objects are devided in:

• flow objects:
• activities: task, subprocess
• gateways: AND-, OR-, ....-gateways
• events: message events (incoming of al letter)
  

• connecting objects:
• sequence flows: conecting the flow objects
• message flows: shows that 2 messages become chagened
  

• swimlanes:
• pool: participant in workflow
• lane: classification of the pool
  

• artifacts:
• textannotation: comment which can be allocated to an element
• data object: rest which is to process in the business process
• groups: additive which is to process in the business process

BPEL

• XML-based
