数字图书馆互操作信息服务体系框架的研究

Research on Interoperable Mediation of Digital Library

提出了一种数字图书馆互操作信息服务体系框架模型(IMDL),系统采用组件式结构设计,实现了图书馆多种异构信息服务的集成,具有动态性和可扩展性。系统中间过程交换信息格式采用RDF,完成协议转换、查询转换和结果合成。以中国数字图书馆公司的异构数字资源为背景,介绍了模型的具体实现和应用测评。

Information heterogeneity is one of the main challenges faced by digital libraries. An interoperable mediation for digital library (IMDL) is introduced. IMDL is based on component architecture and integrates heterogeneous information services, which is dynamic and extensible. IMDL uses RDF as information exchange format, and implements protocol translation, query translation and result integration. The paper also describes the implementation and evaluation of IMDL based on heterogeneous data source of China Digital Library Corporation.
