This Technical Report gives guidelines for using the unified modelling language (UML) for defining and documenting interfaces between intelligent transport systems (ITS) and transport information and control systems (TICS). It presents these guidelines in the context of a case study for the creation of an ITS/TICS data dictionary and submissions to the ITS/TICS data registry.
In UML [6], an interface is a collection of operations that used to specify a service of a class or component.
The ITS/TICS data registry defined in ISO 14817 builds on this definition by mapping an operation to a message, and then it extends the definition of an interface to be a dialogue (i.e. a collection of messages within an implied protocol). This Technical Report conforms to these steps.
