信息技术.远程教育、教育和培训中个性化的灵活性和可访问性.第3部分:“全部访问”数字资源描述

[中文适用范围]： ISO/IEC 24751 旨在满足残疾学习者和受其环境限制的学习者的需求。本部分 ISO/IEC 24751 提供了一种通用语言来描述数字学习资源，以促进将这些资源与学习者的无障碍需求和偏好相匹配。元数据可用于至少两个与无障碍相关的目的：记录对无障碍规范或标准的合规性（例如，为遵守立法采购政策），并使资源能够满足用户的需求和偏好。本部分 ISO/IEC 24751 解决了后一个目的。断言符合无障碍规范或标准的元数据不属于本部分 ISO/IEC 24751 的范围。本部分 ISO/IEC 24751 旨在与 ISO/IEC 24751-2 结合使用，后者提供了一种描述用户希望如何访问在线学习内容及相关应用程序的方法。本部分 ISO/IEC 24751 旨在描述可以调整以改善可访问性的计算机系统（包括联网系统）的方面。它们不旨在解决非数字系统，后者可以包括物理位置、其他人、外部流程等。本部分 ISO/IEC 24751 侧重于描述影响用户如何感知、理解或与资源交互的资源特征的描述，包括：a) 资源中使用的感官模式，b) 资源的可调整方式，即文本是否可以自动转换，c) 资源接受的输入方法，以及 d) 可用的调整。本部分 ISO/IEC 24751 提供了描述学习资源的信息模型，以便根据 ISO/IEC 24751-2 描述的个别学习者偏好和需求可以与计算机中介学习环境中的适当用户界面、工具和学习资源相匹配。 [外文原描述]： ISO/IEC 24751-3:2008 provides a common language for describing digital learning resources to facilitate matching of those resources to learners' accessibility needs and preferences (as defined in ISO/IEC 24751-2). This description is one side of a pair of descriptions used in matching user needs and preferences with education delivery (as described in ISO/IEC 24751-1). ISO/IEC 24751-3:2008 discusses the basic principles adhered to in developing this model for describing digital learning resources. It explains: the assumptions made in developing ISO/IEC 24751-3:2008, the notion of an original and adapted resource, the major categories of metadata for original and adapted resources, the notion of an access mode for a resource, what is meant by adaptability, and the importance of interoperability and the role played by consistent implementation in interoperability. It contains the information model for ISO/IEC 24751-3, including the attribute, allowed occurrence and datatype of each element. It defines and describes how the terms in the information model should be used, and explains how ISO/IEC 24751-3:2008 can be extended. It discusses conformance to ISO/IEC 24751-3. Conformance is dependent on the role played by the conformant technology. Conformance requirements for both education delivery applications, resources and metadata authoring tools are explained. ISO/IEC 24751-3:2008 provides a consolidated list of all the terms defined in ISO/IEC 24751-3:2008, sorted in French alphabetical order, the ISO French language equivalent terms and definitions, and the codes representing the gender of the French terms. The vocabulary codes, values and associated rules of application are defined. An informative list of recommended default values for the learner preferences and needs is provided. It lists existing bindings of the IMS Access for All Metadata Specification Version 1 (ACCMD) that serves as the reference specification for ISO/IEC 24751-3:2008. It describes information scenarios for applying ISO/IEC 24751-3:2008 and gives informative implementation examples. Use of ISO/IEC 24751-3:2008 will assist in matching individual learner needs in a computer-mediated learning environment with the necessary user interface and resources needed to meet those needs.
