物联网（IoT）.物联网系统的互操作性.第3部分:语义互操作性

[中文适用范围]： 本文档提供了物联网系统语义互操作性的基本概念，如 ISO/IEC 21823-1 的方面模型所述，包括：核心本体对语义互操作性的要求；如何使用本体和开发特定领域应用程序的最佳实践和指导，包括需要允许可扩展性和与外部本体的连接；本体的跨领域规范和形式化，以提供现有本体的协调利用；相关的物联网本体以及在模块化、可扩展性、可重用性、可伸缩性、与上层本体的互操作性等方面的特征和方法的比较研究；展示语义互操作性的必要性和要求的用例和服务场景。 [外文原描述]： 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.
