  2. What is XML/EDI? • This is the present attempt to combine the best features of traditional EDI (which has a broad industry support) with the improvements in technology offered by XML. It is EDI with XML, or XML with EDI - depending on the perspective. • In an XML/EDI message, the EDI information is explicitly labelled using tag names. Reference may be made via Internet to a Document Type Definition (DTD) - which contains structure declaration and relevant sets of code values. • Web browsers are expected to support XML; therefore, XML/EDI messages could be transmitted in any way: e-mail, VAN, Internet etc.

  3. Characteristics of XML/EDI • Support W3C XML standard • Compatible with EDI (X12 or EDIFACT) • Business data exchanges • Support business processes • Provide business document and process templates • Use public network for business transactions • Time and cost efficiency • Ref Fig. 7.1
