OASIS has formed a new technical committee to develop an XML-based protocol for managing complex, B2B transactions over the Internet. The OASIS Business Transactions Technical Committee plans to build an open specification for XML message interfaces that will support the coordination and processing of Web services from different organizations. The new OASIS committee initially plans to base its work on the Business Transaction Protocol (BTP) specification, submitted to the Consortium by BEA Systems. BTP allows complex XML message exchanges to be tracked and managed as loosely coupled `conversations’ between businesses. OASIS welcomes the submission of other suitable technologies for consideration in this work. Organizations and individuals interested in business transaction issues are invited to join the OASIS Business Transactions Technical Committee and participate in this development.
