WG 4 - ISO/IEC JTC 1/SC 41/WG 4

ISO/IEC 30161-2:2023 specifies the following items for the transport interoperability between nodal points in the IoT data exchange platform (IoT DEP):
– requirements;
– functional blocks;
– operation mechanism.

ISO/IEC 21823-4:2022 specifies the IoT interoperability from a syntactic point of view. In ISO/IEC 21823-1: Framework [2], five facets are described for IoT interoperability, i.e. transport, semantic, syntactic, behavioural and policy. In this document, the following specifications for IoT interoperability from syntactic viewpoint are included;
– A principle of how to achieve syntactic interoperability among IoT systems which include IoT devices
– Requirements on information related to IoT devices for syntactic interoperability
– A framework for processes on developing information exchange rules related to IoT devices from the syntactic viewpoint

ISO/IEC 21823-3:2021 provides the basic concepts for IoT systems semantic interoperability, as described in the facet model of ISO/IEC 21823-1, including:
– requirements of the core ontologies for semantic interoperability;
– best practices and guidance on how to use ontologies and to develop domain-specific applications, including the need to allow for extensibility and connection to external ontologies;
– cross-domain specification and formalization of ontologies to provide harmonized utilization of existing ontologies;
– relevant IoT ontologies along with comparative study of the characteristics and approaches in terms of modularity, extensibility, reusability, scalability, interoperability with upper ontologies, and so on, and;
– use cases and service scenarios that exhibit necessities and requirements of semantic interoperability.

ISO/IEC 30161-1:2020(E) specifies requirements for an Internet of Things (IoT) data exchange platform for various services in the technology areas of:
• the middleware components of communication networks allowing the co-existence of IoT services with legacy services;
• the end-points performance across the communication networks among the IoT and legacy services;
• the IoT specific functions and functionalities allowing the efficient deployment of IoT services;
• the IoT service communication networks’ framework and infrastructure; and
• the IoT service implementation guideline for the IoT data exchange platform

IEC 21823-2:2020 (E) specifies a framework and requirements for transport interoperability, in order to enable the construction of IoT systems with information exchange, peer-to-peer connectivity and seamless communication both between different IoT systems and also among entities within an IoT system. This document specifies:
• transport interoperability interfaces and requirements between IoT systems;
• transport interoperability interfaces and requirements within an IoT system

ISO/IEC 21823-1:2019(E) provides an overview of interoperability as it applies to IoT systems and a framework for interoperability for IoT systems. This document enables IoT systems to be built in such a way that the entities of the IoT system are able to exchange information and mutually use the information in an efficient way. This document enables peer-to-peer interoperability between separate IoT systems.
This document provides a common understanding of interoperability as it applies to IoT systems and the various entities within them.

ISO/IEC 30140-4:2018 The ISO/IEC 30140 series provides general requirements, reference architecture and high-level interface guidelines supporting interoperability among underwater acoustic sensor networks (UWASNs). Part 4 provides information on interoperability requirements among entities within a UWASN and among various UWASNs.
