The official ebXML white paper states that the vision of ebXML is to create a single global "electronic marketplace" where enterprises of any size and in any geographical location can meet and conduct business with each other through the exchange of XML based messages. ebXML is an end-to-end solution between ebXML compliant software. However, B2B e-marketplace business models do not include such end-to-end B2B models that trading partners exchange XML or EDI based messages with each other. Therefore, this paper aims to clarify the difference between ebXML and B2B public e-marketplace as well as to discuss the application of ebXML to public e-marketplace for making a right decision to adopt a new B2B e-business technology.
