Intelisys announced that IEC-Enterprise, Version 4.0, supports full-scale interoperability between all buyers and suppliers, regardless of the data protocol. A long-time proponent of open standards on the Internet, Intelisys built an architecture that facilitates a broad buying community by enabling fluent data exchange of documents in many formats including any variant of XML. Intelisys is also working with Microsoft Corp. to accelerate the adoption of business-to-business electronic commerce. The companies plan to integrate Intelisys’ operating XML definitions with the Microsoft BizTalk Framework to define schema for communicating business-to-business e-commerce transactions.
