Model-Driven Business Document Evolution

The United Nations Centre for Trade Facilitation<br> and Electronic Business (UN/CEFACT) provides a conceptual,<br> model-driven approach, named Core Components (CC), for<br> creating business document models. These business document<br> models are essential for defining service interfaces of systems<br> following the Service-oriented Architecture (SOA) paradigm.<br> However, in such a highly dynamic environment with everchanging<br> market demands, business partners are confronted<br> with the need to constantly adapt their systems. This implies<br> revising conceptual business documents as well as adapting<br> the corresponding service interface definitions. In this position<br> paper, we discuss evolution challenges encountered while using<br> CC in industry, present our current framework, as well as<br> future challenges for model-driven business document evolution<br> in service-oriented systems.
