INTEROPERABILITY FOR IoT SYSTEMS –

Part 1: Framework
FOREWORD
1) ISO (the International Organization for Standardization) and IEC (the International Electrotechnical Commission)
form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC
participate in the development of International Standards through technical committees established by the
respective organization to deal with particular fields of technical activity. ISO and IEC technical committees
collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in
liaison with ISO and IEC, also take part in the work. In the field of information technology, ISO and IEC have
established a joint technical committee, ISO/IEC JTC 1.
2) The formal decisions or agreements of IEC and ISO on technical matters express, as nearly as possible, an
international consensus of opinion on the relevant subjects since each technical committee has representation
from all interested IEC National Committees and ISO member bodies.
3) IEC, ISO and ISO/IEC publications have the form of recommendations for international use and are accepted
by IEC National Committees and ISO member bodies in that sense. While all reasonable efforts are made to
ensure that the technical content of IEC, ISO and ISO/IEC publications is accurate, IEC or ISO cannot be held
responsible for the way in which they are used or for any misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees and ISO member bodies undertake to
apply IEC, ISO and ISO/IEC publications transparently to the maximum extent possible in their national and
regional publications. Any divergence between any ISO, IEC or ISO/IEC publication and the corresponding
national or regional publication should be clearly indicated in the latter.
5) ISO and IEC do not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. ISO or IEC are not responsible
for any services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or ISO or its directors, employees, servants or agents including individual experts
and members of their technical committees and IEC National Committees or ISO member bodies for any
personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for
costs (including legal fees) and expenses arising out of the publication of, use of, or reliance upon, this ISO/IEC
publication or any other IEC, ISO or ISO/IEC publications.
8) Attention is drawn to the normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this ISO/IEC publication may be the subject of
patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights.
International Standard ISO/IEC 21823-1 was prepared by subcommittee 41: Internet of Things
and related technologies, of ISO/IEC joint technical committee 1: Information technology.

INTRODUCTION
Internet of Things (IoT) systems involve communications between different entities. This
applies to connections between different IoT systems. It also applies to the many connections
that exist within IoT systems. The various entities and their connections are described in
ISO/IEC 30141.
The ISO/IEC 21823 series addresses issues that relate to interoperability of the
communications between IoT systems entities. ISO/IEC 21823-1 describes a general
framework for interoperability of IoT systems. This includes a facet model for interoperability
which includes five facets of interoperability (i.e. transport, syntactic, semantic, behavioural
and policy). This document addresses the framework to achieve interoperability for IoT; the
specific facets are addressed in other parts of ISO/IEC 21823.
