开放信息模型的设计

The Designs of an Opening Information Model

信息交换平台是一个基于点对点(Peerto Peer)的信息发布系统。在这个系统里,从信息的产生、采集、加工、存储、发布、消费到监管,形成了一个完整的信息生命体系。基于XML技术,经过对信息交换平台的信息描述深入的研究,提出了开放信息模型(OIM),对信息进行统一的描述,使信息可以跨平台发布。OIM研究目标有两个:一个是信息模型的设计(信息模型的设计重点在于对数据库查询语句的XML Schema的设计和数据清洗模型的设计);另一个是信息模型在信息交换平台里的实现。限于篇幅,本文介绍信息模型的设计。

Information exchange platform is a message publish system that based on peer to peer architecture. In this system, there is an integrated information circulation forming a lifetime including information production, collection, process, storage, publish, consu- ming and custody. The research of based on XML the information exchange platform of descript the information, put forward an Open- ing Information Model （OIM） so that to descript the information uniformly, that it can be used for crossing from one platform to anoth- er. OIM are two research aims： one is to design a Information Model（The designs of XML Schema of database Standard Query Lan- guage （SQL） and Data Cleaning Model. ） ; the other is to make sure how to use it in the Information Exchange platform, limit to length, this paper introduce the designs of Information Model.
