本文件定义了一个在学生信息系统（SIS）（也称为学生管理信息系统）之间记录和交换学习者成绩信息的模型，以及第三方供应商汇总信息的模型。 此外，本文档定义了对学习者流动成就奖（LMAI）模型的改进，以表示数字文凭补充（DDS）。 注意:所提出的模型并不是为了定义学习者流动信息的整个范围的表示，而是为了定义参与正式学习过程的学习者的官方、机构证明的成就信息的正式结构化表示，以便于其记录和随后在学习者流动可能的任何国际区域内的交换。当然，按照本文件结构和呈现的成绩信息可以用于其他目的，例如，提供成绩描述，以丰富电子档案袋中学习者拥有的报告。然而，关于文件的指导和用于正式成就报告以外的目的的信息组织超出了本文件的范围。

This document defines a model for the recording and exchange of learner achievement information among student information systems (SIS) (also known as student management information systems), as well as the aggregation of information by third party suppliers.
In addition, this document defines refinements to the learner mobility achievement award (LMAI) model for representing the digital diploma supplement (DDS).
NOTE The proposed model proposed is not intended to define the representation of the entire spectrum of learner mobility information but to define the formally structured representation of official, institutionally attested achievement information for learners engaged in formal learning processes, in order to facilitate its recording and subsequent exchange within any international area within which learner mobility is possible. Achievement information structured and presented in compliance with this document could, of course, be used for other purposes, for instance, to provide descriptions of achievement to enrich a learner-owned report in an e-portfolio. However, guidance on the document and the organisation of information for purposes other than the representation of formal achievement reports is outside the scope of this document.
