SOV-4b – Service State Model

The SOV-4b specifies the possible states a service may have, and the possible transitions between those states.

In specifying a service, it is often necessary to specify the allowable states so as to constrain how implementations of the service will behave. SOV-4b is a specification of those states, and the possible transitions between them.

Usage

The intended usage of the SOV-4b includes:

• Service specification.

Product Description

A SOV-4b is a state machine diagram that shows the states a service may have.

Creating a Service State Model

To create a Service State model:

1. Click on Service State Model in the Action Artifact area, and then select Create New Diagram.
2. You are creating a table for managing the state diagrams. Type a name for the table. You can create multiple tables based on different contexts (e.g. by phases, purposes, etc).
3. This opens a table where you can create and manage state diagrams. Click on New Service State Machines Definition above the table to create a new row.
4. Under the first column, select the context to create state diagram, which is a ServiceSpecification.
5. Under the second column, create the state diagram(s). The diagram created will be added to the selected context element as a sub-diagram.
