Abstract
The United Nation´s Center for Trade Facilitation and Electronic Business (UN/CEFACT) is a standardization body known for its work on UN/EDIFACT and ebXML. One of its most recent developments is UN/CEFACT´s Modeling Methodology (UMM). The UMM standard is used to model inter-organizational business processes in the B2B domain. With the increasing availability of electronic governmental services over networks, the frontier between B2B and B2G/G2G disappears. Today one expects a governmental institution to react like any other business partner. Therefore also governments now face the interoperability and compatibility issues as regular businesses do. In order to allow two governmental institutions to collaborate, a methodology uniquely depicting the inter-organizational process from a global perspective is needed. In this paper we propose to use UN/CEFACT´s Modeling Methodology in the eGovernment domain. UMM allows the definition of a global choreography which is then being used to derive local orchestrations for each business partner. Such orchestrations can then be used by enterprise applications in a service oriented context. As an example, a real-world scenario from the waste transport domain within the European Union will be shown. Furthermore the possible integration in the context of the We-Go project [3] is examined.
