ebXML and Web Services: Is this a fair assessment?

["Chiusano Joseph" <chiusano_joseph@bah.com>]

All,

I was not involved in ebXML until after May 2001 (although I monitered
various listservs prior to that), so I don't have as solid an
appreciation as I would like regarding ebXML and Web Services. Can
someone please tell me if the following is a fair assessment - my
intention is to be as accurate as possible, and not controversial (I've
numbered the points below for easy referral):

(1) The ebXML initiative began before Web Services became prominent;
therefore there are many aspects of ebXML that do not utilize Web
Services to as full a potential as they may have otherwise. 

(2) For example, the emerging OASIS Web Services Business Process
Execution Language (WS BPEL) is centered on the Web Services hierarchy
presented in WSDL (portType, operation, message, etc.) while the ebXML
Business Process Schema Specification (BPSS) is centered on the concept
of "business documents". 

(3) An exception to this is the ebXML Messaging Service (ebMS)
specification, whose foundation is SOAP. 

(4) However, many of the ebXML specifications have incorporated Web
Services since their original version - one example is the inclusion of
a SOAP interface to ebXML Registry in its 2.0 version.

Thanks,
Joe
