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