A registry model for UN/CEFACT's core components

Business documents exchanged in a service-oriented context play a crucial role in the definition of service interfaces. Only if both partners have a common agreement on the data exchanged, automated business interactions are possible. The United Nations Center for Trade Facilitation and Electronic Business (UN/CEFACT) provides a reliable and interoperable solution for conceptual business document definitions with UN/CE-FACT's core components technical specification. However, document definitions aren't available in a centralized manner to all interested business partners. In order to allow for an easy search and retrieval of core component business document definitions, a registry is needed. Business partners may retrieve service interface definitions from the registry and adapt their software accordingly in order to engage in automated business interactions. We specify a registry meta model on top of ebRIM, registering core component artifacts and defining their inter-dependencies.
