5 Internet of Things Reference Architecture (IoT RA) conformance
To claim conformance, the description of a concrete system architecture as provided by a vendor or
system integrator should use the terminology and modelling concepts defined in this document, within the scope of their specific use case.
NOTE A separate conformity guide can be developed that can provide specific guidance to meeting and evaluating conformity to ISO/IEC 30141 to a broader set of entities beyond actual system descriptions.
6 IoT RA goals and objectives
6.1 General
The IoT Reference Architecture (IoT RA) represented in this document describes generic IoT system
characteristics, a Conceptual Model, a Reference Model and a number of architectural views aligned
with the architecture descriptions defined in ISO/IEC/IEEE 42010. The IoT RA outlines what the
overall structured approach for the construction of IoT systems shall be by providing an architectural
structure framework. In short, the IoT RA provides guidance for the architect developing an IoT system and aims to give a better understanding of IoT systems to the stakeholders of such systems, including device manufacturers, application developers, customers and users.
This document has the following descriptions:
1) the generic characteristics of IoT systems, outlining the characteristics expected from an IoT system;
2) the Conceptual Model (CM), describing the key concepts characterizing an IoT system;
3) the Reference Model (RM), providing the overall structure of the elements of the architecture;
4) a set of relevant architecture views, describing the architecture from a number of perspectives.
This document supports the following important standardization objectives:
a) to enable the production of a coherent set of standards for IoT;
b) to provide a technology-neutral reference point for defining standards for IoT; and
c) to encourage openness and transparency in the development of a target IoT RA and in the
implementation of IoT systems.
Figure 2 illustrates how the IoT RA is derived from a Conceptual Model and a set of characteristics that define a Reference Model and one or more architectural views.
6.2 Characteristics
The generic characteristics are described in Clause 7, which focuses on a number of key properties that an IoT system typically exhibits. Different application specializations can differ in terms of the actual quantification of these properties, but it is important for an IoT architect to consider how important the respective categories are for the particular system being designed. There are no characteristics that are required of any particular IoT system.
6.3 Conceptual Model
The Conceptual Model (CM) contains a number of vital concepts and describes how they relate to each other logically. Together with the generic characteristics, it provides the background and motivation for the architectural elements discussed in the architectural views in Clause 10. CM is described in Clause 8.
