教学资源库规范化构建研究

摘要

In order to achieve the resources sharing and reusing by solving the resources' exchange, inquiry and extraction,a standardized description is proposed for the teaching resources from two aspects of metadata and camponent. Using triad to described the component resources and adopts four parts to package the resources content. The storage patterns of distributed storage centralized sharing is proposed by comparing the advantages and disadvantages of centralized and distributed storage.The results show that describing the teaching resources based on the component is advantageous in teaching resources reconstruction and reuse.%为了解决资源的交换,查询、提取,实现资源共享和重用的目的,从元数据和构件2个层面对教学资源进行规范化地描述.采用三元组描述构件资源,对资源进行内容包装.比较集中式和分布式存储的优缺点提出分布存储、集中共享的存储模式.结果表明基于构件描述教学资源的思想,有利于教学资源的重构和复用.
