Health Level 7 (HL7) is a non-profit consortium dedicated to developing and publishing protocol specifications for application level communications among diverse health data acquisition, processing, and handling systems. Todd Freter of the Sun XML Technology Center created an annotated presentation that provides an overview of HL7's ebXML proof-of-concept demonstration.

The presentation defines ebXML, electronic business extensible markup language, as a joint initiative of the UN/Centre for Trade Facilitation and Electronic Business (UN/CEFACT ) and the Organization for the Advancement of Structured Information Standards (OASIS). ebXML is supported by Sun, IBM, CommerceOne, and others.

The ebXML mission is to provide an open XML-based infrastructure, enabling the global use of electronic business information in an interoperable, secure, and consistent manner by all parties. Other goals are a global electronic marketplace where enterprises of any size, anywhere can:

• Find each other electronically
• Conduct business through the exchange of XML-based messages: - Using standard message structures - According to standard business-process sequences - With clear business semantics - According to standard or mutually agreed trading partner agreements -Using off-the-shelf business applications

Additional topics discussed in the presentation:

• ebXML architectures (including illustrations)
• other related standards
• ebXML today and tomorrow

The presentation can be found in the Enterprise section of the XML at Sun web site.
