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

ISO 14306:2017 defines the syntax and semantics of a file format for the 3D visualization and interrogation of lightweight geometry and product manufacturing information derived from CAD systems, using visualization software tools that do not need the full capability of a CAD system. ISO 14306:2017 has been adopted as a 3D visualization capability in addition to the ISO 10303 series. The file format supports the following information:

(1) facet information (triangles), stored with geometry compression techniques

(2) visual attributes such as lights, textures and materials

(3) product manufacturing information, such as dimensions, tolerances and other attributes

(4) boundary representation (b-rep) solid model shape representations. Several alternatives are available, including a representation based on the geometry standard defined in ISO 10303

(5) configuration representations

(6) delivery methods such as asynchronous streaming of content

ISO 14306:2017 does not specify the implementation of, or definition of a run-time architecture for viewing or processing of the file format.

This document is the first of a family of standards. ISO 12637-1:2006 defines a set of fundamental terms that can be used in the drafting of other International Standards for graphic technology. In order to facilitate their translation into other languages, the definitions are worded so as to avoid, where possible, any peculiarity attached to one language. The entries in ISO 12637-1:2006 are arranged alphabetically.

Artificial intelligence (AI) computing differs from generic computing in terms of device formation, operators, and usage. AI server systems, including AI server, cluster, and high-performance computing (HPC) infrastructures are designed specifically for this purpose. The performance of these infrastructures is important to users not only on generic models but also on the ones for specific domains. Formal methods for the performance benchmarking for AI server systems are provided in this standard, including approaches for test, metrics, and measure. In addition, the technical requirements for benchmarking tools are discussed.

This document specifies guidelines for developing a cybersecurity framework. It is applicable to cybersecurity framework creators regardless of their organizations' type, size or nature.

Data format requirements for blockchain systems are established in this standard. This standard addresses data structures, data types, and data elements.

This standard defines a baseline architectural framework and defines functional roles for blockchain-driven supply chain finance (SCF) implementations, e.g., core enterprise, supplier, bank, blockchain platform provider, and so on. The procedures of registration, asset issuance, asset transfer, financing based on asset on chain, asset clearing and settlement, and asset tracing, are explained. Finally, the technique requirement of the business system, and blockchain platform are discussed.

Blockchain interoperability is the ability of two or more blockchain systems or applications to exchange information and to mutually use the information that has been exchanged. The interfaces and protocols play a very important role in realizing interoperability. Therefore, the standard of cross-chain interoperability interfaces and protocols, especially those for data authentication and communication among homogeneous and heterogeneous blockchains systems, is needed. Such protocols coordinate blockchains while supporting multiple cross-chain models and levels to meet business demands without the need to customize gateways or exchanges for specific use cases. Provided in this standard are an infrastructure of cross-chain interoperability, as well as interfaces and protocols of data authentication and communication for homogeneous and heterogeneous blockchain interoperability. The protocols include the distributed identity protocol, metadata protocol, on-chain proof transformation protocol, and cross-chain communication protocol.

This standard defines a technical reference framework and terminology for the platform of blockchain in electronic contracts. Functional requirements and technical indicators are also defined.

This standard defines requirements for multiple aspects of user identification and Anti-Money Laundering on cryptocurrency exchanges, such as KYC (Know Your Customer) and AML (Anti-Money Laundering) regulations, outsourcing proper compliance measures to third-party solutions, and building up a self-regulatory layer of security and accountability among exchanges. It is to keep customers from malignant influence of unethical and illegal money that can be traced back inside/outside the cryptocurrency space. It is different from the IEEE P2140.2 standard, which is based on the protection of customer cryptographic assets.

This standard defines the performance metrics of cryptocurrency payment between consumers and merchants required to quantify the experience assessment of both consumers and merchants, such as the duration time required to complete a transaction made in cryptocurrency through a general process of cryptocurrency payment.
