Sv-St Service State
The UAF Service State viewpoint is a diagram type that enables you to get a state-like view of Service Connectors (which are really the state of a Service as it is doing something – sending resources to another Service) and ServiceSpecifications or ServiceInterfaces (which are analogous to the transition of a Service from one state to another).
One easy way to model this viewpoint is to:
1 Open the Choices dialog (right-mouse click on diagram workspace, and then select Choices) – and select-and-drag ServiceConnectors already created in the encyclopedia onto the diagram workspace.
2 Optionally select Format > Symbol Format > Line Style and choose the line style – usually Elliptical Arcs or Straight – Any Orientation work well for a state-machine diagram. See Important tips on line drawing mode for advice on how to draw Elliptical Arcs.
3 Build transitions between the Service Connectors (represented as circular state nodes) – the transitions are actually the ServiceInterfaces or ServiceSpecifications needed in the architecture (remember – you can draw ServiceConnectors between ServiceInterfaces (that belong to a ServiceSpecification) or draw ServiceConnectors directly between ServiceSpecifications (if you have not defined interfaces).
