摘    要:基于多XML文档的政务数据交换平台以映射函数作为基本计算单位,将XML数据交换操作分解为数据抽取、函数及数据组合3个步骤,通过映射函数的组合实现复杂的XML数据交换操作。相对目前采用XSLT技术进行XML文档格式转换的方式,该平台具有开发效率高、可扩育性强等优点。

关 键 词:XML  映射函数  数据交换

Abstract:An engine of data mapping based on multi-XML documents named GDEP is designed and realized in this paper. GDEP uses the mapping function as the basic calculating unit, and separates the whole data mapping operation into three steps: data extracting, function calculating and data composing. The complex operations of data mapping could be completed by the combination of mapping functions. Compared with the present way in which XSLT is used to transfer the format of XML document, the GDEP possesses the advantages of high deveolping efficiency and strong extensibility.
Keywords:XML  Mapping function  Data exchanging
