Schema transformation between different modeling languages in the INSPIRE context using GML

The INSPIRE Directive requires that EU member states adjust their spatial data systems in a way that will allow unifying them in interoperable geospatial web services and standardized transfer formats. European data models, called INSPIRE Data Specifications, are defined for important topics as a final goal of transformation. The Unified Modeling Language (UML) is used for the definition of the INSPIRE data models. At the moment, most of the countries use their own spatial data systems and also their own data models. Some countries (e.g. Germany and Switzerland) define their data models with the UML and apply UML profiles as well. By defining transformations between data models using the same UML profile it is possible to unify spatial data into a single system. However, the spatial data models of Germany, Switzerland and INSPIRE are represented by UML profiles that don't conform to the UML specification, but expand it with their own individual elements. This additionally complicates the transformation. One of the approaches to this problem is to define a core UML profile as an intersection of different UML profiles. The transformation between data models conforming to different UML profiles could then be defined using the core UML profile as an intermediate step. The goal of this thesis is to explore the Geography Markup Language (GML) specification as a possible solution for the above mentioned core UML profile.
