  The problem of defining and managing the detector description, in the quite complex context such as the software environment of the Atlas experiment is being handled by applying a generic approach to the software design. It is centered around the notion of a generic model, independent of both the application (simulation, reconstruction, visualisation, etc...) and the specificities of all subdetectors. This model permits in particular to provide a parametric description of the physical elements and of the logical organisation of the detectors (including a mechanism for a generalised identification scheme). Due to this genericity of the approach, the industry standard XML is able to describe the model (using the DTD syntax) and the effective descriptive parameters, including materials. Using this standard brings simplicity and opens a wide range of commodity tools for visualisation and validation. Work is currently active on applying the model up to the digitization, onto the various clients of the detector description.
