Semantic Interoperability through the Definition of Conceptual Model Transformations
SUMMARY To solve the currently urgent problem of collecting critical data across system and country borders without modification of any source system, we present a model based 4step procedure. Its core is a new language for "horizontal" mapping of conceptual models, which is introduced by a small but multi face example. It is further shown that this PIM PIM mapping of platform independent models needs to be completed by an appropriate "vertical" PIM PSM mapping between platform independent and platform specific models from the conceptual level to the (physical) format level. Together with geometric operations this combination of two model mapping types provides an effective semantic interoperability. Our work is based on practical experiences with the application of the MDA in Switzerland and a short review of these is given as introduction. Finally, the outlook sketches the near future with the integration of our 4step procedure into web services providing e.g. a transformation enabled model driven WFS.
