RDF is the format of choice to exchange data between software components of a corporate system. That’s why we decided to use it in a recent work at Renault, in the field of technical documentation. The prototype of a new repository for repair and diagnostic information was modeled with OWL. REST web services using RDF as data format were built on this repository, to provide access to improved repair and diagnostics methods. This report describes how Semantic Web technologies were used. It is not about the "grand vision" of the Semantic Web, but it could be of interest for those eager to promote the use of these technologies in the enterprise.
