BPMN 2.0 - Business Process Model and Notation
Activities
Task A Task is a unit of work, the job to be performed. When marked with a symbol it indicates a Sub-Process, an activity that can be refined. A Transaction is a set of activities that logically belong together; it might follow a specified transaction protocol. An Event Sub-Process is placed into a Process or Sub-Process. It isactivated when its start event gets triggered and can interrupt the higher level process context or run in parallel (noninterrupting) depending on the start event. A Call Activity is a wrapper for a globally defined Task or Process reused in the current Process. A call to a Process is marked with a symbol.

Conversations
A Conversation defines a set of logically relatedmessage exchanges. When marked with a symbol it indicates a Sub-Conversation, a compound conversation element. A Call Conversation is a wrapper for a globally defined Conversation or SubConversation. A call to a Sub-conversation is marked with a symbol. A Conversation Link connects Conversations and Participants.

Choreographies
Participant A Choreography Task Participant B A Choreography Taskrepresents an Interaction (Message Exchange) between two Participants. Participant A Sub-Choreography Participant B Participant C A Sub-Choreography contains a refined choreography with several Interactions. Participant A Call Choreography Participant B A Call Choreography is a wrapper for a globally defined Choreography Task or Sub-Choreography. A call to a Sub-Choreography is marked with a symbol.Event Sub-Process Interrupting Event Sub-Process Non-Interrupting Boundary NonInterrupting

Events
Standard None: Untyped events, indicate start point, state changes or final states. Message: Receiving and sending messages. Timer: Cyclic timer events, points in time, time spans or timeouts. Escalation: Escalating to an higher level of responsibility. Conditional: Reacting to changed businessconditions or integrating business rules. Link: Off-page connectors. Two corresponding link events equal a sequence flow. Error: Catching or throwing named errors. Cancel: Reacting to cancelled transactions or triggering cancellation. Compensation: Handling or triggering compensation.
