pattern was unable to satisfy all the possibly contrasting expectations, and
that only the abstraction level of a reference model could provide the common
ground for any single IoT-based application.
6.2.1 The IoT-A Reference Model
This IoT Reference Model provides the highest abstraction level for the definition
of the IoT-A Architectural Reference Model. It promotes a common
understanding of the IoT domain. The IoT Reference Model is composed by
different models that refer to specific aspects of the modeling exercise. In particular,
models composing the Reference Model are the IoT Domain Model
that describes the generic components of a generic architecture, an IoT Information
Model explaining the data semantics typical for an IoT system, and an
IoT Communication Model in order to understand specifics about communication
between many heterogeneous IoT devices and the Internet as a whole.
Furthermore, the functional model and a global security analysis provide two
important aspects of the IoT context.
The definition of the IoT Reference Model is conforming to the OASIS
reference model definition.
