Background

From The MODAF Service Oriented Viewpoint p15:

An SOV-4c product does not specify the sequencing of an orchestrated set of services (see OV- 6c). Its purpose is to specify the general sequence of interactions that are possible for a given service.

Presentation

From The MODAF Service Oriented Viewpoint p15:

  • 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 lifeline to which messages are shown passing. It is also possible to show timing constraints between messages.
