Microsoft Corp. released a draft of the Microsoft BizTalk Framework version 2.0. This newest version of the BizTalk Framework has been redefined to be SOAP 1.1 compliant, thereby allowing BizTalk Framework XML documents to travel over a network in the form of SOAP messages. In addition, version 2.0 has been extended to include specifications for reliable server-to-server messaging, guaranteeing exactly-once delivery of business documents over the Internet. Multi-Part MIME encoding guidelines also have been added to the framework to support the inclusion of one or more non-XML attachments within a BizTalk message. Microsoft BizTalk Server 2000 will support BizTalk Framework 2.0 as the protocol for reliable interoperability over the Internet. The BizTalk Framework takes advantage of XML and MIME to provide the specifications for XML-based integration within and between organizations. The support for the SOAP 1.1 specification, which was recently submitted to and acknowledged by W3C, will allow developers to create applications and services that can be more easily integrated, independent of operating system, programming model or programming language. The new reliable messaging capabilities defined in BizTalk Framework 2.0 allow organizations to reliably transmit information via the Internet using standard transport protocols such as HTTP and SMTP. The inclusion of support for Multi-Part MIME, an alternative to inline encoding of binary information, provides guidelines for encoding and decoding of one or more non-XML attachments within a BizTalk XML message. The BizTalk Framework 2.0 specification is available for review at
