GB/T 41782.3-2024 Internet of things - Interoperability for systems - Part 3: Semantic interoperability
1 Scope
This document provides the basic concepts for IoT systems semantic interoperability, as described in the facet model of ISO/IEC 21 823-1, 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;
——use cases and service scenarios that exhibit necessities and requirements of semantic interoperability.
