Introduction of GB/T 41782.4-2024

GB/T 41782.4-2024 Internet of things - Interoperability for systems - Part 4: Syntactic interoperability 1 Scope This part specifies the IoT interoperability from a syntactic point of view. In this document, the following specifications for IoT interoperability from a 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. 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. ISO/IEC 20924, Internet of Things (IoT) – Vocabulary 3 Terms and definitions For the purposes of this document, the terms and definitions given in ISO/IEC 20924 and the following apply. 3.1 instance individual entity having its own value and possibly its own identity [SOURCE: ISO 19103:2015, 4.20] 3.2 metamodel special kind of model that specifies the abstract syntax of a modelling language Note 1: A model is an instance (3.1 ) of a metamodel. Note 2: IoT syntactic interoperability is achieved by information exchange rules through the structure, data format, and syntactic constraints using syntactic aspects of the metamodel. [SOURCE: ISO/IEC 19506:2012, modified – The description that follows the definition has been deleted. Notes to entry have been added.] 3.3 model abstraction of some aspects of reality [SOURCE: ISO 19109:2015, 4.15] 3.4 property particular characteristic of an object type [SOURCE: ISO 16484-5:2017, 3.2.74] 3.5 syntactic interoperability interoperability such that the formats of the exchanged information can be understood by the participating systems Note 1: System means IoT system. Note 2: IoT device, IoT gateway, sensor and actuator are considered as system. [SOURCE: ISO/IEC 19941:2017, 3.1.4, modified – Notes to entry have been added.] 4 Abbreviated terms CRS coordinate reference system EPIoT extrinsic properties of physical IoT devices IPIoT intrinsic properties of physical IoT devices IoT Internet of Things JSON JavaScript Object Notation MOF Meta Object Facility UML Unified Modelling Language XML extensible markup language
