UN/CEFACT's Modeling Methodology (UMM) is a mod-eling approach for describing the choreography of B2B processes. UMM is developed by the United Nations Center for Trade Facilitation and Electronic Business (UN/CE-FACT) and currently defined as a UML profile. Thereby, it constrains the UML for the specific needs of B2B. As we learned, using UML as the(More)

SOA is said to enable quick and inexpensive changes of the IT in order to establish new business partnerships or to reflect changes in existing partnerships. However, current approaches to(More)
UN/CEFACT's Modeling Methodology (UMM) is a UML profile for modeling global B2B choreographies. The basic building blocks of UMM are business transactions, which describe the exchange of a business document and an optional response. In addition to these business document exchanges, UMM business transactions mandate business signals that acknowledge the(More)
The United Nation's Centre for Trade Facilitation and Electronic Business (UN/CEFACT) is an e-business standardization body. It is known from its work on UN/EDIFACT and ebXML. One of its ongoing work items is the UN/CEFACT modeling methodology (UMM) for modeling global choreographies of B2B scenarios. The goal of UMM is defining a shared business logic(More)
The Web Services Transaction protocol family includes the WS-AtomicTransaction and the WS-BusinessActivity specifications in order to carry out distributed transactions in a Web Services (WS) environment.

Due to their wide industry coverage and long-standing establishment, they will presumably continue to play an important role for some time. EDI systems are typically not " process-aware " , i.e.,(More)
The development of inter-organizational systems requires a well defined development process. UN/CEFACT's Modeling Methodology (UMM) provides such a development process. We served as the editing team of the UMM 1.0 foundation module, which is defined as a UML profile. First experiences of applying UMM in real world projects have disclosed some limitations.(More)
