  7. Notations and Syntax The CASU Framework Classification Analysis Today's topics

  8. The CASU framework • Creation (C): When has a new process instance to be created? • Activation (A):Which entry points are activated? • Subscription (S):For which start events are subscriptions created? • Unsubscription (U):How long are subscriptions kept?

  9. CASU: Creation • C-1 Ignorance • C-2 Single Condition Filter • C-3 Multi Condition Filter • C-4 Single Event Trigger • C-5 Multi Event Trigger

  10. CASU: Creation • C-1 Ignorance • C-2 Single Condition Filter • C-3 Multi Condition Filter • C-4 Single Event Trigger • C-5 Multi Event Trigger

  11. CASU: Activation • A-1 Initial State • A-2 All Start Places • A-3 True Conditions • A-4 Occurred Events • A-5 Occurred Eventsand Conditions

  12. CASU: Activation • A-1 Initial State • A-2 All Start Places • A-3 True Conditions • A-4 Occurred Events • A-5 Occurred Eventsand Conditions

  13. CASU: Subscription • S-1 All Subscriptions • S-2 No Subscriptions • S-3 Reachable Subscriptions

  14. CASU: Subscription • S-1 All Subscriptions • S-2 No Subscriptions • S-3 Reachable Subscriptions x ?

  15. CASU: Unsubscription • U-1 Until Consumption • U-2 Until Termination • U-3 Timer-based • U-4 Event-based • U-5 Proper Completion

  16. CASU: Unsubscription • U-1 Until Consumption • U-2 Until Termination • U-3 Timer-based • U-4 Event-based • U-5 Proper Completion

  17. CASU: Unsubscription • U-1 Until Consumption • U-2 Until Termination • U-3 Timer-based • U-4 Event-based • U-5 Proper Completion
