3.4.2 Modelling of example scenario

The IoT Information Model is a meta-model that defines the structure of key
aspects of the information being managed in an IoT system. Therefore, unlike
the Domain Model (see the recurring example in Section 3.3.1), it would
typically not be directly instantiated (see information view Section 4.2.3 and the
related Design Choices (Section 5.2.10) for this purpose). Nevertheless, for
illustration purposes, we sketch here how the information relevant for our
example scenario from Section 2.3 could be modeled.
