1. ebXML Convergence with SOAP and Attachments
Dick Brooks, John Ibbotson and Henrik Frystyk Nielsen

2. 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

3. Disclaimer !!!
Note that this is
WORK IN PROGRESS

7. Summary ebXML TRP will be SOAP compliant
Conversion follows KISS principle !
Restructuring for SOAP + Attachments
No other major redesign work
Adoption of XML DSIG
