IT in general

This standard defines a technical architecture as well as primary functional and non-functional requirements for blockchain fusion servers.

This standard defines an application model and technical framework for green power identification based on blockchain. This standard also specifies the technical and operation management requirements of green power identification based on blockchain.

This standard defines an evaluation model and evaluation index system for using blockchain in low carbon zones, combining carbon emission scenarios and zone types. This standard also defines the technical requirements and management requirements for using blockchain for low carbon zones, including carbon accounting data sources, data storage, data interaction, data accounting, emission factor database establishment, carbon accounting method selection and prediction.

This standard defines a trusted data circulation platform based on blockchain and distributed ledger technologies. The system overview of trusted data circulation platform is defined including underlying computation engine layer, blockchain and DLT core function layer, trusted data circulation layer, and interface layer. The functional modules, data circulation processes, technical and security requirements are specified. This standard includes recommendations for controlling the allowable purposes and amount of data utilization, and for data privacy and resistance to tampering during the relevant data operations.

This standard establishes a system designed to trade data through domain-independent and principled marketplaces operating under a unified architecture. It defines terminology, a reference model, and the roles and functions of data providers, data users, and data marketplaces. The standard provides an overview of the data trading system using its reference model.

This standard specifies the terminology, technical reference framework, basic functional requirements, and technical indicators for the platform of blockchain-based e-commerce transaction evidence collecting, which is the foundation of digital business interactions.

The technologies of this document specified are description languages and vocabularies to describe virtual world objects. The adaptation engine is not within the scope of this document. This document specifies syntax and semantics of the tools used to characterize a virtual world object related metadata: Virtual World Object Characteristics (VWOC) as an XML Schema-based language which enables one to describe a basic structure of avatars and virtual world objects in virtual environments.

This document specifies requirements for the preparation, revision and presentation of digital product definition data, hereafter referred to as data sets, complementing existing standards. It supports two methods of application: 3D model-only and 3D model with 2D drawing in digital format. The structure of this document presents requirements common to both methods followed by clauses providing for any essential, differing requirements for each method. Additionally, its use in conjunction with computer-aided design (CAD) systems can assist in the progression towards improved modelling and annotation practices for CAD and engineering disciplines, as well as serving as a guideline for CAx software developers.

This document specifies an image-based representation model that represents target objects/environments using a set of images and optionally the underlying 3D model for accurate and efficient objects/environments representation at an arbitrary viewpoint. It is applicable to a wide range of graphic, virtual reality and mixed reality applications which require the method of representing a scene with various objects and environments. This document:

(1) defines terms for image-based representation and 3D reconstruction techniques;

(2) specifies the required elements for image-based representation;

(3) specifies a method of representing the real world in the virtual space based on image-based representation;

(4) specifies how visible image patches can be integrated with the underlying 3D model for more accurate and rich objects/environments representation from arbitrary viewpoints;

(5) specifies how the proposed model allows multi-object representation; and

(6) provides an XML based specification of the proposed representation model and an actual implementation example (see Annex A).

This standard defines the data format, classification and application programming interface of blockchain in the field of electronic evidence.

The current blockchain has problems such as a wide variety of chains, independent design rules for each identity account, and different cryptographic curve signature algorithms. If the traditional private key mode is used to manage multiple accounts on the same chain or multiple accounts on different chains Identity requires users to perform multiple backups, and faces complex management and authentication problems. Therefore, the design of hierarchical deterministic schemes and related proposals have emerged. The IEEE P3209 standard will unite many blockchain technology providers to jointly formulate international standards for hierarchical deterministic schemes, output uniform and standardized cryptographic derivation rules between different chains, and determine multiple blockchains through mutual signature and self-certification of private keys of different chains. The same identity corresponding to the public and private keys on the chain.

This standard defines the functional requirements in data compliance, governance and risk management in the operational process for Blockchain-based IoT data management systems.
