Interactions (Section

5.5)

Derive interaction patterns for

prevailing usage scenarios

As briefly discussed in Section 4.2.2, the interaction viewpoint

is an integral part of the Functional View, but the IoT ARM is

situated at a far too high level of abstraction in order to allow

the definition of the functional interaction sequences at the

reference-architecture level. In order to mitigate this systemic

shortcoming of the IoT ARM, we decided to discuss some few

usage scenarios of IoT systems that can shed at least some

light on how such interaction patterns can look like, and they

also provide inspiration for how such patterns might look like

for the usages for which the concrete architecture is built.

Derive

information view

Information view

(Section 4.2.3)

Define information and data model

for all FGs and also for the

exchange with applications and

devices (see Section 4.2.3)

The IoT Information View provides several pieces of general

information. First, it elaborates on general information

descriptions (description of Virtual Entities service descriptions;

associations between services and Virtual Entities). Second, it

elucidates the information handling of FCs both from an

interaction- and from an interaction-scenario point of view.

Third, it discusses the information life cycle.

Derive

operational and

deployment view

Deployment &

operational view

(Section 4.2.4)

Define how to deploy and how to

operate the system.

This section discusses in depth how deployment of IoT

systems. Since the deployment patterns vary a lot, this section

of course focuses on common topics and patterns. First, it

identifies other views and device descriptions as viewpoints for

the deployment. This aids in translating information in these

views into actionable deployment knowledge. This section also

discusses the question of connectivity solutions and where to

host the services. It also touches upon the important questions
