Alexandria, Va, December 10, 2002 - At the XML Conference and Exposition 2002 this week in Baltimore, the electronic business community will have a chance to hear first-hand about the X12 Reference Model for Extensible Markup Language (XML) Design, which describes a method for assembling flexible business messages. Mike Rawlins of Rawlins EC Consulting and Lisa Shreve of Syscom Strategies, Inc., who led the development of the reference model for the Accredited Standards Committee (ASC) X12, will give the presentation on Wednesday, December 11 at 11:00 a.m. at the Baltimore Convention Center, Room 314.

The session will address guidance provided by the reference model on the use of XML in ASC X12 business messages. At the heart of the reference model is the Context Inspired Component Architecture (CICA) that presents seven levels of semantic granularity, from the entire document at the top, down to primitives that contain one discrete piece of data. The approach encourages maximum reuse and flexibility, with a minimum of complexity. The reference model is also designed to align with draft ebXML core components specifications.

"This reference model puts ASC X12 in the forefront of e-business standards development," said Jerry Connors, president of Data Interchange Standards Association (DISA), the secretariat for ASC X12. "It provides a blueprint for e-business documents that builds on the work of ebXML core components, yet still provides a migration path for current EDI users."

DISA, a co-host of XML 2002, will present more information about ASC X12 and its vertical industry affiliates at Booth 539 in the eventís exhibit hall, from Tuesday, December 10, to Thursday, December 12.
