本文件规定了一种元数据结构，通过指定数据元素及其属性来描述各种在线教育平台上的引导者信息，从而存储、呈现和交换在线学习引导者（OLF）信息
本文件提供了OLF的通用信息模型，用于描述适用于在线提供的便利和培训服务的相关信息，包括提供便利的人员、人员的从属关系、便利能力、便利实践、提供的便利服务、学习者的评论和证词，以及相关的社交网络信息。概念数据模型允许OLF信息属性的语言多样性，并提供了一个灵活的元数据模式来描述它们。
注1:尽管本文件提供了如何指定需要隐私保护的元数据元素的建议，但并未提供如何实施隐私保护措施的详细方法或技术
注2:对于具有隐私的元数据，ISO/IEC 19788-1中的应用程序配置文件可用于标记与隐私有关的数据元素，并使用条件对其进行定义。OLF信息隐私保护方法和技术，如设计隐私，可根据实施者的需要进行选择和应用。

This document specifies a metadata structure to store, present and exchange online learning facilitator (OLF) information by specifying the data elements and their attributes to describe facilitator’s information on various kinds of online education platforms.
This document provides a generic information model of OLF to describe relevant information that applies to the facilitation and training services provided online, and includes information about the person offering facilitation, the affiliation of the person, facilitation ability, facilitation practices, the facilitation service offered, learners’ reviews and testimonies, and related social network information. The conceptual data model allows the linguistic diversity of OLF information attributes and offers a flexible metadata schema to describe them.
NOTE 1 Although this document provides suggestions on how to designate metadata elements that require privacy protection, it does not provide detailed methods or techniques for how to implement privacy protection measures.
NOTE 2 For metadata with privacy, the application profile in ISO/IEC 19788-1 can be used to tag data elements concerning privacy and define them with conditions. OLF information privacy protection methods and techniques, such as privacy-by-design, can be selected and applied as needed by implementers.
