Abstract

Prior to conducting business via the Web, business partners agree on the business processes they are able to support. In ebXML, the choreography of these business processes is described as an instance of the so‐called business process specification schema (BPSS). For execution purposes the BPSS must be defined in the exact business context of the partnership. Reference models for B2B processes developed by standard organizations usually span over multiple business contexts to avoid a multitude of similar processes. In this paper we present how business collaboration models following the UN/CEFACT Modeling Methodology (UMM) are expressed in ebXML BPSS. To allow a mapping from multi‐context business collaboration models to a context‐specific choreography in ebXML BPSS we extend UMM to capture constraints for different business contexts
