Stage 2
Using an ontology development tool, such as Protege, build up models of the Things or entities in the domain model. In this example, the image shows the design of a Vehicle Function Digital Twin as a subclass of Vehicle. Other subclasses of the class Vehicle include Style, Infotainment System and Model.
The Vehicle Function Digital Twin is a collection of functions that can be subject to fail if it is impacted by misinformation from other infrastructure services such as Parking systems or Traffic Lights.
Continue the development of ontological models for other Things in the domain such as Traffic Lights. Extend this development with the definition and classification of the security controls, events and monitoring pattern requirements.
Each class in the ontology is supported by the definition of Class Properties, Domains and Ranges. This forms a semantic triple where the Domain Class or Subject has a Predicate or Property relationship with the Object or Range Class. This helps to enrich the data by making it more explicit and through further verification by the extended relationships.
