Construction and Implementation of Government Data Mapping Engine Based on Multi-XML Documemts

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.
