XML-based Web Data Model
基于XML的Web数据模型

Some semi-structured data models have been analyzed,and some shortcomings of these models as Web data model are point out. Based on XQuery 1.0 and XPath 2.0 data model,a new XML-based Web Data Model(XWDM)is presented. XWDM gives a solution to the problem of name heterogeneous, which is resulted from the name difference of the same data element in different Web pages,and solves the problem of infinite circulation which is common during Web data querying.
