The tool enables to model XML data on PIM and PSM level as specified by XSEM. It offers a standard environment commonly offered by other tools for conceptual modeling such as ER or UML class diagram editors.

The tool enables to model the data on the following two levels:

• Platform-Independent Model Level (PIM)
  • Data is modeled independently of its representations in different types of XML documents (i.e. a conceptual schema of the problem domain is created)
  • UML class diagrams are applied for modeling
    • packages, classes, class attributes, stereotypes, (n-ary) associations


• Platform-Specific Model Level (PSM)
  • Models how the data is represented in different types of XML documents
  • Each PSM diagram models one type of XML documents
  • User can work with components of PIM diagrams
  • Organizing them to hierarchical structure
  • Using extended constructs proposed in [1] to model how the data is represented in more complex XML structures (XML elements vs. XML attributes, irregular structure, mixing structured and unstructured data, ordering, ...)
  • Automatic translation of PSM diagrams to representations in XML Schema
