In this paper, an approach to overcome the limits of XML encoded device descriptions by employing semantic Web technologies is presented. Starting with an illustration of the state of the art of working with XML device descriptions, reasons for a need to overcome these limits are given. The semantic Web, as idea and implementation, is then introduced shortly, followed by a presentation of the architectural concept. To conclude, this paper will highlight upsides and downsides of the system, and give a short overview over planned work.
