云模式下大学区教育资源服务平台及关键技术研究

摘要

This paper describes the architecture of Wide-range District Public Education Resources Service Platform based on the cloud computing model.As for the"data exchange and sharing between heterogeneous information systems"in the construction of the resource database,a design scheme for the metadata standard which meets the national standard and the real needs of the service platform is presented by using the metadata technology.And also the XML meta-markup and the description method are given.The study mentioned above is of value in sharing education resources within a Wide-range District,optimizing resources allocation and balancing educational development.%论文对基于云计算构建的大学区教育资源公共服务平台进行了架构分析，同时针对资源库建设中异构信息系统之间数据交换共享的关键问题，以学区教育为核心，利用元数据技术提出了一套符合国标且服务平台实际需求的元数据标准设计方案，同时给出了X ML 标识及描述方法。上述研究对实现大学区内教育资源共享，促进资源优化配置，提高教育水平的均衡发展有一定的价值。
