从哈工大图书馆的实际情况出发,对一类分布式数字图书馆系统结构进行研究,运用中间构件技术和智能主体技术构造一种三层客户/服务器模式的数字图书馆系统结构模型,该模型可扩展性和安全性好,对分布异构的数字资源具有很强的集成能力。另外,还对相关的问题进行探讨,给出一种信息模型,使信息组织灵活方便;提出一种优化的资源调度方法,能使系统运行成本降低;同时,还对数字图书馆的互操作性问题进行讨论,提出相应的互操作性规范。
Based on the actual situation of HIT Library, this paper studies the structure of a type of distributed digital library system, and constructs a three-layer client / server model of digital library system architecture by using intermediate component technology and intelligent agent technology. Scalability and security, distributed heterogeneous digital resources with strong integration capabilities. In addition, the related problems are also discussed, and an information model is given to make the information organization flexible and convenient. An optimized resource scheduling method is proposed to reduce the operating cost of the system. At the same time, the interoperability of digital libraries Discuss the issue, put forward the corresponding norms of interoperability.
