Abstract:

XML is universally recognized as the standard document format for the purpose of interchange and device-independent presentation. Literature shows many efforts towards the development of formal and conceptual models for XML, although no commonly accepted model exists as yet. In this paper, we present a survey of some formal and conceptual modeling techniques, and discuss the merits and shortcomings of such techniques. We then present HNR (Heterogeneous Nested Relations) a formal modeling method for representing XML, and discuss how this formal model could be used to derive many useful results on XML query language, and how this could lead to a potential conceptual modeling technique as well.
