GB/T 41782.3-2024Internet of things - Interoperability for systems - Part 3: Semantic interoperability (English PDF)

1 Scope

This document gives the basic concepts for semantic interoperability of IoT systems, as described in the aspect model of ISO/IEC 21823-1, including.

--Core ontology requirements for semantic interoperability;

--Best practices and guidelines on how to use ontologies and develop domain-specific applications, including allowing extensibility and connecting to external the needs of the entity;

--Formalization of cross-domain specifications and ontologies to uniformly leverage existing ontologies;

--Related IoT ontologies, as well as their modularity, extensibility, reusability, scalability, and interoperability with upper-level ontologies Confronted with comparative studies of characteristics and methods;

--Use cases and service scenarios that reflect the necessity and demand for semantic interoperability.
