ebXML Convergence with SOAP and Attachments

• Dick Brooks, John Ibbotson and Henrik Frystyk

Background

• ebXML started in November 1999, continued through
  2000
• ebXML viewed SOAP 1.0 as RPC and proprietary
• SOAP 1.1 and XML Protocol formation seen as
  possible convergence route
• Strong requirement for non XML (binary)
• SOAP Attachments not available
• Technical willingness for convergence
• Some IP issues outstanding
• Resolution at Vancouver (Feb 2001) meeting
• IP statements by SOAP 1.1 and Attachments owners
• Work in progress by TRP WG to convert messaging
  services spec
• Approval by ebXML plenary
