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2部分:“全部访问”个人需求和数字交付用参数选择

[中文适用范围]： ISO/IEC 24751-2 提供了描述在学习或访问数字化交付资源或服务时学习者的需求和个人偏好的通用信息模型。该描述是与数字化交付（如 ISO/IEC 24751-1 中所述）匹配用户需求和个人偏好的成对描述之一。该模型将学习者的个人需求和个人偏好分为三类：a. 显示：资源应如何呈现和结构化；b. 控制：资源应如何控制和操作；c. 内容：应提供哪些补充或替代资源。本部分旨在满足 ISO/IEC 24751-1 中定义的残障学习者的需求以及处于不利环境中的任何人的需求。本部分的目的之一是提供一种机器可读的方法来陈述用户关于数字化教育或学习的需求和偏好。本部分可独立使用，例如向学习者/用户交付所需的或期望的用户界面，也可与 ISO/IEC 24751-3 结合使用，以交付满足用户需求和个人偏好的数字资源。 [外文原描述]： ISO/IEC 24751-2:2008 provides a common information model for describing the learner or user needs and preferences when accessing digitally delivered resources or services. 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 24751-2:2008 discusses the basic principles adhered to in developing this model for describing personal needs and preferences. It explains: the rationale for using a functional approach to describing needs, possible methods of creating a personal needs and preference statement, the major groupings of needs and preferences within the standard, the use of different needs and preferences statements in different contexts, how needs and preferences can be ranked with respect to priority, and the use of generic and application-specific needs and preference specifications. It contains the information model for ISO/IEC 24751-2:2008, including the attribute, allowed occurrence and datatype of each element. It defines and describes how the terms in the information model should be used. Conformance to ISO/IEC 24751-2:2008 is discussed. Conformance is dependent on the role played by the conformant technology. Conformance requirements for both education delivery applications and alternative access systems are explained. ISO/IEC 24751-2:2008 provides a consolidated list of all the terms defined in ISO/IEC 24751-2:2008, 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 Learner Information Package Accessibility for LIP - Version 1 [ACCLIP] that serves as the reference specification for ISO/IEC 24751-2:2008. It describes information scenarios for applying ISO/IEC 24751-2:2008 and gives informative implementation examples. Use of ISO/IEC 24751-2:2008 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.
