基于网格的数字图书馆互操作技术研究

Research on the Technologies of Digital Library Interoperability Based on Grid

以支持大规模资源共享和协作为核心的网格技术在解决数字图书馆(DLs)互操作问题,尤其是在异构平台兼容、集成已有系统方面有着独特的优势。本文对目前数字图书馆互操作主要解决方案进行分析和对比,包括:分布式搜索(Distributed Search)、元数据收集(Metadata Harvesting)、中间件(Middleware)技术,指出各自的优势和不足,提出一种新的数字图书馆互操作框架——数字图书馆网格DL Grid,探讨利用先进的网格技术解决各数字图书馆的互操作性问题。

Grid technology, which supports a large scale resources share and collaboration, has particular advantage in solving digital library interoperability, especially in integrating existing heterogeneous systems and platform, First this paper gives an analysis and comparison of existing conventional approaches of digital library interoperability, including Distributed Search, Metadata Harvesting , Middleware Technology, and advantages and disadvantages of each method is pointed out, in the end, a new framework of DLs interoperability, Digital Library Grid, is presented, which try to solves interoperability problem of digital library using advanced grid technology.
