Chapter 2: A Comprehensive Set of Standards

                                            Place










                                            however, XML’s use could be limited to carefully prearranged data
                                            exchanges with well-established business partners.

                                            However, business standards are generally less well-developed and agreed
                                            upon than XML’s core technical standards. Unlike XML technical
                                            standards, all of which are established and maintained by the W3C,
                                            business standards are developed by a variety of public and private sector
                                            organizations, including industry consortia, and are not always universally
                                            supported. For example, a number of different approaches to addressing
                                            the process of conducting business transactions have been proposed.
                                            Currently, at least three of them are vying for support and offer
                                            functionality that is in part overlapping and incompatible. These
                                            approaches include the following:


        ebXML                               UN/CEFACT and OASIS have approved a modular suite of ebXML
                                            specifications that enables the conduct of business over the Internet. 2
                                            EbXML’s goal is to allow any enterprise—of any size or in any industry—
                                            to conduct business electronically with any other entity anywhere in the
                                            world. Launched in November 1999, the ebXML project finished its initial
                                            development phase in May 2001. At that time, it established a set of design
                                            rules for data dictionaries as well as a number of significant reference
                                            documents, including a technical architecture, business process
                                            specification schema, registry information model, registry services
                                            specification, requirements specification, message service standard, and
                                            collaboration-protocol profile and agreement. Figure 6 shows a
                                            representative ebXML transaction involving two organizations that locate
                                            each other through an ebXML registry and then negotiate and carry out the
                                            transaction based on ebXML specifications.
