This document describes best practices for use case projects in terms of characterization, template, plan and maintenance. It is intended to developers of use case projects, including in the context of standardisation. The document can be used to complement existing methodology standards such as IEC 62559 or IEC Guide 125.

ISO/IEC 18023-1:2005 addresses the concepts, syntax and semantics for the representation and interchange of environmental data. It specifies:

- a data representation model for expressing environmental data;

- specifications of the data types and classes that together constitute the data representation model; and

- an application program interface that supports the storage and retrieval of environmental data using the data representation model.

ISO/IEC 18023-1:2005 also specifies topological, rule-based, and other constraints that ensure appropriate data can be available for applications that rely on automatically generated behaviours when interacting with environmental data.

Recommendation ITU-T F.748.15 specifies a framework for digital human application systems, and proposes corresponding subjective and objective metrics for the dimensions of image, speech, animation, interactive processing and multimodal input/output. This Recommendation can be used to guide relevant parties to test, select or evaluate a digital human application system. The metrics can reflect the current state of the digital human application system by providing meaningful comparison dimensions.

Recommendation ITU-T F.748.14 specifies requirements and evaluation methods for non-interactive two-dimensional (2D) real-person digital human application systems, in terms of image, voice, movement, display, etc. It can be used to guide relevant parties to test, select or evaluate a non-interactive 2D real-person digital human application system. The evaluation methodology can reflect the current state of a non-interactive 2D real-person digital human application system by providing meaningful comparison dimensions.

This recommendation specifies the framework and requirements for the construction of 3D intelligent driven digital human application system based on multimedia services. The scope of this Recommendation includes:

(a) Overview of 3D intelligent driven digital human application system.

(b) Framework of 3D intelligent driven digital human application system.

(c) Requirements of 3D intelligent driven digital human application system.

This document describes guidelines for developing education and training systems using VR/AR/MR technology. It defines VR/AR/MR based information modelling that can be used for education and training systems. It provides procedures and methods to be used when developing 3D VR/AR/MR based education and training systems using ISO/IEC JTC 1 standards. It also provides a systematic approach to developing VR/AR/MR based applications for systems integration areas. This work will:

- define concepts of VR/AR/MR based education and training.

- define an information modelling architecture for VR/AR/MR based education and training systems.

- specify standards based functional components for VR/AR/MR based education and training systems.

- specify framework components for implementing VR/AR/MR based education and training systems.

- include use cases for VR/AR/MR based education and training systems based on the information modelling architecture.

Device hardware technology for VR/AR/MR based education and training systems is excluded from this draft.

ISO/IEC 19776-3:2015, Extensible 3D (X3D), defines a system that integrates 3D graphics and multimedia. Conceptually, each X3D file is a 3D time-based space that contains graphic and aural objects that can be dynamically modified through a variety of mechanisms. This part of ISO/IEC 19776 defines a mapping of the abstract objects in X3D to a specific X3D encoding written out in a compact binary form. Each X3D file encoded using the Compressed binary encoding:

a. supports all of the purposes of X3D files defined in the X3D abstract specification ISO/IEC 19775; and

b. encodes X3D constructs in a compressed binary format, taking advantage of geometric and information-theoretic compression techniques.

X3D files encoded using the Compressed binary encoding may be referenced from files using other X3D encodings, and may itself reference other X3D files encoded using other X3D encodings. Sets of X3D files that use multiple encodings can only be processed by browsers that support all of the utilized X3D encodings.

ISO/IEC 19775-2:2015, Extensible 3D (X3D), defines a system that integrates 3D graphics and multimedia. Conceptually, each X3D file is a 3D time-based space that contains graphic and aural objects that can be dynamically modified through a variety of mechanisms. This part of ISO/IEC 19776 defines a mapping of the abstract objects in X3D to a specific encoding using the technique defined in ISO/IEC 14772 ? Virtual reality modeling language (VRML). Each Classic VRML-encoded X3D file:

a. supports all of the purposes of X3D files defined in ISO/IEC 19775; and

b. encodes X3D constructs in Classic VRML format.

A Classic VRML-encoded X3D file may be referenced from files using other encodings and may itself reference X3D files encoded using other encodings. Such files can only be processed by browsers which conform to all of the utilized encodings.

Conceptually, each X3D file is a 3D time-based space that contains graphic and aural objects that can be dynamically modified through a variety of mechanisms. This part of ISO/IEC 19776 defines a mapping of the abstract objects in X3D to a specific X3D encoding using the Extensible Markup Language. Each XML-encoded X3D file:

a. supports all of the purposes of X3D files defined in the X3D abstract specification ISO/IEC 19775; and

b. encodes X3D constructs in an XML format.

An XML-encoded X3D file may be referenced from files using other X3D encodings and may itself reference other X3D files encoded using other X3D encodings. Such files can only be processed by browsers that conform to all of the utilized X3D encodings.

ISO/IEC 19775-2:2015 specifies a standard set of services that are made available by a browser so that an author can access the scene graph while it is running. Such access is designed to support inspection and modification of the scene graph.

ISO/IEC 18024-4:2006 specifies a language-dependent layer for the C programming language. ISO/IEC 18023-1 specifies a language-independent application program interface (API) for SEDRIS. For integration into a programming language, the SEDRIS API is embedded in a language-dependent layer obeying the particular conventions of that language.

ISO/IEC 18023-3:2006 defines a binary encoding for DRM objects specified in ISO/IEC 18023-1 according to the abstract syntax specified in ISO/IEC 18023-2.
