基于网格技术的数字图书馆应用研究

文章围绕数字图书馆网格的设计和建设,介绍了计算网格以及Web Service的基本概念和体系结构,引入了将网格技术和Web Service相结合的Globus项目组的GT4开发工具包。在此基础上分析了数字图书馆的资源整合以及一站式网格信息服务的设计和相关技术,研究比较了目前流行的数字图书馆网格体系结构,提出采用四层体系结构构建数字图书馆网格,并设计出基于此体系结构上的资源整合和网格信息服务的架构,初步实现了数字图书馆网格环境。

Research on the application of digital library based on grid technology

Focusing on the design and construction of digital library,this article makes an introduction to grid technology,the basic concept and systematic structure of Web Service,and the package of Globus technology combined with the grid environment on the Linux server.The authors of this article explore the consistency and functional advantages of the grid technologies used in the field of digital libraries,compare the popular grid systems of digital libraries and advance the four-tier structure.Based on the GT4 grid environment to package Grid resource,the framework of resources integration and information service of grid technology have been constructed,and a preliminary grid environment of digital library has been realized.
