Presentation

- UML
From The MODAF Service Oriented Viewpoint
p16:
The representation is usually a UML Sequence Diagram.
The product shows a service and the interfaces it exposes – quite often the diagrams can be cluttered if all interfaces are shown, so it is advisable to consider producing multiple SOV-4c products for a given service. Each interface in an SOV-4c has a
lifelineto which messages are shown passing. It is also possible to show timing constraints between messages.
