【摘要】制定教育资源管理系统（ERMS）互操作框架，是实现教育资源有效共享与交换的重要工作。本文首先介绍了ERMS互操作方面的已有相关研究，并在此基础上，提出了一种基于元数据采集的ERMS互操作框架(ERMSIF)。在这种ERMSTF框架中，各个ERMS都是自主的，可以通过元数据采集协议交换与共享资源的元数据。此框架容易实现，而且便于各个ERMS发挥特长，或着重于资源开发，或着重于提供服务，从而可以带动教育资源建设形成产业。

Abstract: It is a prerequisite for sharing and exchanging of education resources to adopt Education Resource Management System (ERMS) Interoperability standards and implement pointpoint exchange between ERMSs. The paper gives a brief survey of the related efforts that have done on research of ERMS interoperability. Then, it puts forward the framework for ERMS interoperability,which is based on metadata harvesting. At the same time, the framework supports pulling and pushing method to gather metadata. In this framework, the component ERMSs is independent and can exchange metadata through metadata harvesting protocol. It is easy to implement the framework. The most important characteristic of this framework is that component ERMSs can choose to focus their efforts on developing resources or on providing services according to their advantages.
