Since start of the standardisation project XPlanung, the Geoinformation Working Group is actively engaged in developping the exchange format XPlanGML for spatially related planning documents. Main emphases were lead management in specifying the UML models for all hitherto existing versions of the standard, leading the XPlanung "Modelling" working group, support of XPlanGML implementations in specialised software applications as well as administration and maintenance of the standard's Internet presentation and Wiki-pages. The pilot implementaion XPlanGML-Toolbox developed in the institute is used nationwide for converting existing plans and testing XPlanGML implementations.
In addition to the standardisation activities the working group is engaged with scientific research on the semantic data model XPlanGML. Main topic are
- Rule-based testing of XPlanGML implementations;
- Automatic conformity testing of XPlanGMl models;
- Visualisation of XPlanGML based spatial plans with SVG vectorgraphics;
- Integration of XPlanGML with other GML based data models (CityGML, GeoSciML) on application level.
