The detector description is an essential component that is used to analyze data resulting from particle collisions in high energy physics experiments. We will present a generic detector description toolkit and describe the guiding requirements and the architectural design as well as the main implementation choices. The toolkit is reusing and combining already existing components and elements from the ROOT geometry package and the Geant4 toolkit to offer a complete and coherent detector description solution aimed to solve all typical problems during the entire experiment life-cycle. All detector description related issues from data processing application required during the experiment life-cyle will be addressed. The design is strongly driven by easy of use; developers of detector descriptions and applications using them should provide minimal information and minimal specific code to achieve the desired result. We like to use the opportunity to also report difficulties combining the ROOT geometry package and the Geant4 toolkit to a coherent detector description when different philosophies or contentions appeared.
