A Conceptual Model for the XML Schema Evolution Overview: Storing, Base-Model-Mapping and Visualization
Thomas Nösinger, Meike Klettke, Andreas Heuer · 2013
In this article the conceptual model EMX (Entity Model for XML-Schema) for dealing with the evolution of XML Schema (XSD) is introduced. The model is a simplified representation of an XSD, which hides the complexity of XSD and offers a graphical presentation. For this purpose a unique mapping is necessary which is presented as well as further information about the visualization and the logical structure. A small example illustrates the relationships between an XSD and an EMX. Finally, the integration into a developed research prototype for dealing with the coevolution of corresponding XML documents is presented. 1.
