Supporting interactive multi-attribute electronic negotiations with ebXML

The inter-organizational character of electronic negotiations raises social, legal, organizational and technical research questions. One of the main weaknesses of electronic negotiation applications today is that they do not sufficiently take into consideration the integration requirements that stem from the latter two of these aspects. Our objective is to design and build an electronic negotiation application that complies with these requirements. A major task within this work is the modeling and specification of the negotiation process and negotiation objects. To meet the integration requirements, the use of standards is essential. In our paper, we apply the ebXML framework to the task of modeling interactive bilateral multi-attribute electronic negotiations. For this purpose, we introduce the negotiation process flow underlying our application scenario. We explain the significance of ebXML for standardized business transaction modeling. We develop ebXML process and object definitions and suggest modifications of and additions to the current ebXML standard. Finally, we discuss the scope and the limitations of our concept and prototype.
