Web 4.0 and virtual worlds

The standard establishes access control requirements for blockchain systems. The standard addresses the following access control attributes of the system, including but not limited to:a) Node permissions - the permissions of block generation, block synchronization, block verification and broadcasting, and sending transactions.b) Smart contract access permissions - interface access control, user access control, and hybrid access control.c) User permissions - registered user permissions and unregistered permissions. The concept of role is applied to differentiate the permissions of registered users, which means permissions vary according to the role of a user.d) Global permissions - user access to deploy smart contracts, and to read smart contracts.

This standard defines a decentralized identity and access management (IAM) framework for the Internet of Things (IoT) based on the emerging concepts such as decentralized identifiers (DIDs) and verifiable credentials (VCs). The framework addresses the integration of DIDs and VCs into the lifecycle of IoT devices as well as the decentralized IoT security services such as device authentication, data authorization and access control.

This standard provides a framework for the implementation, and interaction utilizing Web 3.0 (Web3) in healthcare and life sciences involving privacy challenges. Web 3.0 represents the next iteration of the evolution of the web and is built upon the core concepts of decentralization, openness, and greater user utility. Digital Ledger Technology (DLT) tokens, smart contracts, transactions, assets, networks, off-chain data storage and access architectural patterns, and Web3 permissioned and permission-less DLT are included in the framework.

This guide provides an open, common, and interoperable reference framework model for distributed ledger technology (DLT), such as blockchain in the energy sector. It also covers three aspects:1) Serve as a guideline for Blockchain DLT use cases in Electrical Power industry; energy value industry chain, covering the Renewable energy industry and their renewable related sources services of generation.2) Create guide on reference architecture framework, including interoperability, terminology, functionality, and system interfaces for blockchain DLT applications in the energy sector by building an open protocol and technology agnostic layered framework.3) Evaluate and provide guidelines on scalability, performance, security, and interoperability through evaluation of consensus algorithm, smart contracts, and type of blockchain DLT implementation, etc. for the Energy sector.

This standard provides a common framework for distributed ledger technology (DLT) usage, implementation, and interaction in agriculture. The framework maps DLT terms including transactions, smart contracts, tokens, assets and networks to terms in agriculture, and addresses technical aspects including scalability, security and privacy challenges with regard to DLT in agriculture. Concerns from different stakeholders and requirements in horizontal and vertical categories of agriculture are included in the framework.

This document analyses visualization elements that are key components of the interface between the physical asset and the avatar (digital replica of the physical asset).

The present document collects information on glass-type AR/MR devices in the context of 5G radio and network services. The primary scope of this Technical Report is the documentation of the following aspects:- providing formal definitions for the functional structures of AR glasses, including their capabilities and constraints,- documenting core use cases for AR services over 5G and defining relevant processing functions and reference architectures,- identifying media exchange formats and profiles relevant to the core use cases,- identifying necessary content delivery transport protocols and capability exchange mechanisms, as well as suitable 5G system functionalities (including device, edge, and network) and required QoS (including radio access and core network technologies),- identifying key performance indicators and quality of experience factors,- identifying relevant radio and system parameters (required bitrates, latencies, loss rates, range, etc.) to support the identified AR use cases and the required QoE, and- providing a detailed overall power analysis for media AR related processing and communication.

This recommendation describes the scenarios, general framework, and requirements for a real-time interactive multimedia service (RIMS) under poor network conditions. The RIMS system plays an important role in many scenarios and situations, e.g., emergency relief, remote education and emergency communication. The RIMS requires providing measures for adjustment of coding parameters, including video and audio coding parameters, dynamically, and it requires setting maximal priority of audio communication under low-speed network conditions and configuring usage priority attributes to ensure that high-priority uses have priority of service over low-priority uses.

This document is the first of a family of standards. This document provides an overview of the ISO 8000 series. The following are within the scope of this document:(1) stating the scope of the ISO 8000 series as a whole;(2) establishing the principles of information and data quality;(3) describing the path to data quality;(4) describing the structure of the ISO 8000 series;(5) providing a summary of the content of each part in the ISO 8000 series; and(6) establishing the relationship of the ISO 8000 series to other international standards.

This document describes a visualization framework for data quality in analytics and machine learning. The aim is to enable stakeholders using visualization methods to assess the results of data quality measures. This visualization framework supports data quality goals.

This recommendation identifies the functional requirements for the media processing services. In particular, the scope of this Recommendation includes functional requirements and application scenarios. Media processing services utilize a set of techniques including cloud computing, computing resource virtualization, and job queue processing to dynamically control and manage computing resources, which improves scalability, flexibility, and availability. This Recommendation specifies the functional requirements of general requirements, service provision requirements, service management requirements, security considerations, etc.
