Towards Conceptual Modeling for XML

Today, XML is primarily regarded as a syntax for exchanging structured data, and therefore the question of how to develop well-designed XML models has not been studied extensively. As applications are increasingly penetrated by XML technologies, and because query and programming languages provide native XML support, it would be beneficial to use these features to work with well-designed XML models. In order to better focus on XML-oriented technologies in systems engineering and programming languages, an XML modeling language should be used, which is more focused on modeling and structure than typical XML schema languages. In this paper, we examine the current state of the art in XML schema languages and XML modeling, and present a list of requirements for a XML conceptual modeling language.
