摘要：

研究开放环境中远程教学系统的资源共享，提出社区型P2P资源共享模型，以更加自然的社区型交流方式实现大规模远程教学系统中的学习资源共享.模型基于LOM规范描述数字化学习资源，在结构化纯P2P模式下采样分布式元数据管理方式，充分利用分布于远程教学环境中的存储、计算、带宽等资源.文章给出了社区的形成、社区内部的学习资源信息发布及检索方法，并简要介绍模型实现.

Abstract:

This paper studies the resource sharing in Tele-learning systems.A community P2P learning resource sharing model is proposed and the resource sharing will be restricted in certain communities. The metadata of digital learning resources is stated by LOM standard. By means of distributed metadata management in structured pure P2P topology, the distributed storage and bandwidth can be taken full advantage. The constitution of community, the publication and retrieval of learning resources are specified in this paper as well as implement of the model.
