基于Web Service的信息集成与访问模型研究

针对目前网络中信息的异构性、多样性、分布性等特点，基于Web Service架构构建一个异构信息集成与访问模型。在此模型中，对各种异构信息进行包装并且提出一种通用的reml信息中间格式，将信息注册到信息注册中心，信息请求方获得reml 格式的信息后，使用reml解析器解析并基于浏览器显示给用户。此外，还针对Web Service中的安全问题引入门限闭包授权方案。

On Information Integration and Access Models Built on Web Service

A heterogeneous information integration and access model built on Web Service is proposed, which can accommodate to the heterogeneous, disperse and various information in present internet. The model uses reml (root-element xml) to describe the information which will be changed in deferent systems, then registries it to the information registry center. After the information requesters receiving the reml information, they analyze it with JDOM and exhibit it to users by IE. Another, Threshold closure authorization mechanism was introduced to solve the security problem in Web Service.
