This document provides system life cycle processes to implement and maintain trustworthiness in an IoT system or service by applying and supplementing ISO/IEC/IEEE 15288:2015. The system life cycle processes are applicable to IoT systems and services common to a wide range of application areas.
This International Standard, within the context of methods and tools for MBSSE: (1) Provides terms and definitions related to MBSSE; (2) Defines MBSSE-specific processes for model-based systems and software engineering; the processes are described in terms of purpose, inputs, tasks, and outcomes; (3) Defines methods to support the defined tasks of each process; and (4) Defines tool capabilities to automate/semi-automate tasks or methods.
ISO/PAS 19450:2015 specifies Object-Process Methodology (OPM) with detail sufficient for enabling practitioners to utilise the concepts, semantics, and syntax of Object-Process Methodology as a modelling paradigm and language for producing conceptual models at various extents of detail, and for enabling tool vendors to provide application modelling products to aid those practitioners.
This Recommendation provides concept of digital twin federation and defines requirements for digital twin federation in smart cities and communities.
This draft Recommendation introduces a decentralized service by using DLT and edge computing technologies for IoT devices, and analyses its characteristics and high-level requirements, and provides its functional framework and relevant common capabilities, functionalities and general procedures.
This draft Recommendation introduces a concept of service exposure for decentralized services (DSE) for IoT applications, analyses its common characteristics and high-level requirements, and provides a reference architecture of DSE and relevant common capabilities.
The document describes a formal model and a common representation for a Web of Things (WoT) Thing Description. A Thing Description describes the metadata and interfaces of Things, where a Thing is an abstraction of a physical or virtual entity that provides interactions to and participates in the Web of Things. Thing Descriptions provide a set of interactions based on a small vocabulary that makes it possible both to integrate diverse devices and to allow diverse applications to interoperate. Thing Descriptions, by default, are encoded in a JSON format that also allows JSON-LD processing. The latter provides a powerful foundation to represent knowledge about Things in a machine-understandable way. A Thing Description instance can be hosted by the Thing itself or hosted externally when a Thing has resource restrictions (e.g., limited memory space) or when a Web of Things-compatible legacy device is retrofitted with a Thing Description.
The document presents a process for WoT discovery with two phases: introduction and exploration. The Introduction phase leverages existing discovery mechanisms but does not directly expose metadata; they are simply used to discover Exploration services, which provide metadata but only after secure authentication and authorization. This document normatively defines two Exploration services, one for WoT Thing self-description with a single WoT Thing Description and a searchable WoT Thing Description Directory service for collections of Thing Descriptions. A variety of Introduction services are also described and where necessary normative definitions are given to support them.
This document defines a structured description method, which describes the functionalities of IoT devices, including what functionalities an IoT device can provide, and how to use the functionalities of IoT device. In details, the contents: 1. Define concept of IoT Device Model: what is IoT Device Model, and how it works with underlying IoT communication protocols; 2. Specify structure of IoT Device Model: define the elements of Status, Profile, and Resource; Furthermore, specify the structure of Resource element, to describe the functionalities of IoT devices through Property, Service, and Event; 3. Specify construction method of IoT Device Model: how to build IoT device functionalities based on IoT Device Model; 4. Describe the device interoperability based on the IoT Device Model: IoT Device Model discovery, remote query, remote controlling, subscription and data uploading.
This document provides a collection of representative use cases of Digital Twin applications in a variety of domains.
The document defines a conceptual model for the building of use cases; specifies a use case template ontology, i.e. vocabulary as well as conventions for describing and representing use case contents; provides guidance on building use case templates and on extending a use case ontology to cover the targeted standard; provides examples of use case templates and use cases; and specifies an implementation scheme that will allow use cases to be stored and shared in a repository.
