XCase

XCase is an application designed to act as a case tool for conceptual modeling of XML data based on MDA. The role of the tool is to separate the conceptual modeling process to two levels: Platform-Independent and Platform-Specific Model. From each PSM diagram you can derive an XML schema describing a data view and you can create new diagrams from scratch and save them to your computer, thanks to the integrated editor.

The app allows you to model one or more schemes in a Platform-Specific Model (PSM) where you specify how your data is to be represented in concrete types of XML documents. In this case, the app applies the well-known model of UML class diagrams as PIM and a little augmentation of this model as PSM.Using advanced MDA, the app greatly facilitates not only the design but also the maintenance of the XML schemes in your system. It may come in handy to a broad range of analysts and designers who generally work with XML data. 

It is important to note that the app represents an academic experiment whose  main purpose is to test some novel ideas of applying MDA for XML data modeling in a more advanced way compared to current approaches. In other words, the implemented PSM model has been developed on a theoretical level and XCase should be its proof-of-concept.
