Astract: UN/CEFACT´s Modeling Methodology (UMM) is a well accepted and formal notation to analyze and design B2B business processes. In a service oriented architecture (SOA) environment process specification languages like the Business Process Specification Schema (BPSS) are used to configure B2B information systems. However, mappings from UMM models to BPSS process specifications currently exist just on a conceptual level. This results in a gap between defined B2B processes and BPSS configurable e-commerce systems. Thus, a model driven code generation of BPSS descriptions is required. In this paper we present a technical implementation of a transformation engine that generates BPSS process specifications from a UMM model represented in the XML Metadata Interchange (XMI) language. This implementation bridges the gap mentioned above. It has been used in the EU project GILDAnet to generate BPSS descriptions from logistic processes modeled in UMM.

Astract: UN/CEFACT´s modeling methodology (UMM) is used to develop global choreographies of inter-organizational business processes. UMM models should be publically available in order to foster re-use and to reference them in trading partner agreements. In this paper we define a mapping of UMM models or parts thereof to the ebXML registry information model (RIM).

Astract: UN/CEFACT´s Modeling Methodology (UMM) is a well accepted approach to define inter-organizational business processes. UMM models should be managed in a registry for two reasons: Firstly, business partners supporting the process can find it and bind to it. Secondly, a model - or more important parts thereof - may be reused in another model of an inter-organizational process. Accordingly, registering one model as one object in a registry is not appropriate. Those parts of a model that may be reused must become registry objects themselves. Extracting parts of a model results in objects that are logically inter-related. Thus, a registry model taking care of these inter-relationships is needed. In this paper we present a so-called business collaboration registry model that sits on top of the ebRIM (ebXML registry information model) in order to manage UMM business collaboration models in an ebXML registry. Furthermore, we outline the registry management functions for maintaining models in the registry.

Astract: 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 between business partners and fostering reuse of standardized process building blocks. The latest UMM version is defined as a UML 1.4 profile. In this paper we introduce the main concepts of UMM to realize its vision. Furthermore, the paper elaborates on the necessary UML meta model work-arounds we - as part of the specification´s editing team - took in order to accomplish the B2B requirements. Then we propose a move towards UML 2 that eliminates some of those workarounds. The paper is concluded with the introduction of a UMM modeling tool that we implemented on top of a commercial UML tool.
