ISO/IEC 24751-3:20 08提供了用于描述数字学习资源的通用语言，以促进这些资源与学习者的可访问性需求和偏好（如ISO/IEC 24751-2中所定义）相匹配。该描述是用于将用户需求和偏好与教育交付相匹配的一对描述的一侧（如ISO/IEC 24751-1中所述）。 ISO/IEC 24751-3:20 08讨论了在开发描述数字学习资源的模型时所遵循的基本原则。它解释了:在开发ISO/IEC 24751-3:20 08时所做的假设、原始和改编资源的概念、原始和改编资源的元数据的主要类别、资源访问模式的概念、适应性的含义、互操作性的重要性以及一致实现在互操作性中所起的作用。它包含ISO/IEC 24751-3的信息模型，包括每个元素的属性、允许出现和数据类型。 它定义和描述了如何使用信息模型中的术语，并解释了如何扩展ISO/IEC 24751-3:20 08。 它讨论了与ISO/IEC 24751-3的一致性。一致性取决于一致性技术所扮演的角色。解释了教育交付应用程序、资源和元数据创作工具的一致性要求。 ISO/IEC 24751-3:20 08提供 ISO/IEC 24751-3:20 08中定义的所有术语的综合列表，按法语字母顺序排序， ISO法语等效术语和定义，以及 代表法语术语性别的代码。 定义了词汇代码、值和相关的应用规则。提供了针对学习者偏好和需求的推荐默认值的信息列表。 它列出了作为ISO/IEC 24751-3:20 08参考规范的所有元数据规范版本1（ACCMD）的IMS访问的现有绑定。 它描述了应用ISO/IEC 24751-3:20 08的信息场景，并给出了信息丰富的实施示例。 使用ISO/IEC 24751-3:20 08将有助于在以计算机为媒介的学习环境中，将个人学习者的需求与满足这些需求所需的必要用户界面和资源相匹配。

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.
