物联网（IoT）.物联网系统的互操作性.第4部分:语法互操作性

[中文适用范围]： ISO/IEC 21823 的这一部分从句法的角度规定了物联网互操作性。本文档从句法角度包含了以下物联网互操作性的规范： – 如何实现包括物联网设备在内的物联网系统之间的句法互操作性的原则； – 对物联网设备相关信息的语法互操作性要求； – 从句法角度制定与物联网设备相关的信息交换规则的流程框架。 [外文原描述]： 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
