Modeling ebXML registry service architecture

Department of Telecommunications, Faculty of Electrical Engineering and Computing, University of Zagreb works on the research project named "networked economy", supported by Croatian Ministry of Science and Technology. The project is also recognized by corporate domain and was made a part of an e-business initiative by the Agrokor group. The Agrokor\´s intention is to use the ebXML registry/repository layer as the central point of integration among the many Agrokor\´s affiliates and partners. We have considered different approaches toward ebXML specifications describing registry/repository layer, not only to conform to specifications, but also with vision that careful architecture modeling will enable modularity and flexibility of our solution. This could be vital, as we must bear in mind that specifications are surely going to be improved over certain period of time. This paper describes modeling ebXML registry/repository architecture and concentrates on its registry service part.
