The Case for Conceptual Modeling for XML

Because of its success, XML is increasingly used in many different application areas, and is moving towards the center of applications, evolving from an exchange format to the native data format of application components. These developments suggest that similar to other core areas of application design, XML should be designed conceptually before the implementation tasks of designing markup and writing schemas are approached. In this paper, we describe why conceptual modeling will become an important part of the XML landscape, what issues need to be addressed, and what the requirements for a conceptual modeling language for XML are.
