Functional Views could be derived from the Functional Model. See also

Section 4.2.2 for more detailed information on the functional view.

3.5.2 Functional Model diagram

The IoT Functional Model diagram is depicted in Figure 14 and was derived as
follows:

 From the main abstractions identified in the Domain Model (Virtual

Entities, Devices, Resources and Users) the ―Application‖, ―Virtual

Entity‖, ―IoT Service‖ and ―Device‖ FGs are derived;

 With regards to the plethora of communication technologies that the IoT

ARM needs to support, the need for a ―Communication‖ FG is identified;

 Requirements expressed by stakeholders regarding the possibility to

build services and applications on top of the IoT are covered by the ―IoT

Process Management‖ and ―Service Organisation‖ FGs;

 To address consistently the concern expressed about IoT Trust, Security

and Privacy, the need for a ―Security‖ transversal FG is identified;

 Finally, the ―Management‖ transversal FG is required for the

management of and/or interaction between the functionality groups.
