基于Web服务统一检索系统的设计

通过分析目前数字图书馆统一检索方法,利用Web Services技术,对传统异构数据源集成方法Mediator/WrapPer进行改进,提出一个基于Web Services统一检索方案,以Web服务注册机制代替虚拟视图,在包装器上增加web服务封装及发布功能,构建资源透明访问框架,实现对分布式异构数字图书馆资源的统一检索.

Design of Universal Retrieval System Based on Web Services

Presents a universal retrieval scheme based on Web services by analyzing current universal retrieval methods of digital libraries, applys Web services technology to improve traditional Mediator/Wrapper methods of encapsulating heterogeneous data, uses Web services registration mechanism instead of virtual view, adds functions of Web services encapsulating and publishs on the wrapper, conceives transparent frame of accessing distributed libraries resource, achieves universal retrieval of distributed digital library resources.
