RAPR is a project of the research team Knowledge Management of the DFKI Kaiserslautern in collaboration with John Deere and Agricultural Management Solutions (AMS) in Zweibrücken for the Land Rheinland-Pfalz in Germany. RAPR stands for Raumbezogene Regelwerkzeuge für ein Produktions- und Ressourcenmanagement von Biorohstoffen. It is one component within a larger set of interacting tools which shall realize various services in the agricultural domain. In particular, RAPR connects to the AGROCONNECT plattform, which offers interconnection and messaging services among several systems and uses ebXML to this effect. This connection relies on ebMessaging - so far the project has good experiences with that.
