为促进学习对象的共享与重用,本文提出基于数字权限描述语言的学习对象共享平台。本文根据学习对象权限管理需求,对现有的数字权限描述语言进行修订和扩展,提出学习对象的数字权限描述语言,并以此为基础,设计学习对象共享平台,以期达到重用学习对象的目标。此平台的特点是支持平台之间交换与共享学习对象的数字权限信息。本文还实现了学习对象共享平台的一个原型。

This paper revise and expand the existing digital rights description language according to the requirements of the rights management of learning objects, and propose the digital rights description language of the learning objects. Based on this, we design the learning object sharing platform in order to achieve the goal of reusing the learning objects.
