Kenji, thank you very much for your comments.   It is my hope that the UBL and CEFACT representatives present in Geneva will be able to work out a way to present and pursue their efforts as complementary and unified.   I have two primary concerns.

First, the window of opportunity for obtaining industry and user support for ebXML or any other web services schema is this year.  Another year of continued divergent efforts, in appearance or reality, will impair our ability to promote a unified nonproprietary eBusiness solution.  

Second, the actual technical differences between the two approaches are not great.   If put into the same room, I believe the authors and experts would be able to resolve issues and forge consensual answers.  By continuing to develop in parallel, we are encouraging differing opinions to avoid reconciliation.  In my view we have still failed to bring together the different opinions about modeling and implementation that were raised in Tokyo in 2000.  Both viewpoints have merit:  our project is unlikely to thrive unless we have both forward compatibility with fully-modeled, object-valid systems as well as smooth backwards compatibility with simple deployment of document-based messages such as the EDIFACT set. 

Ray, Klaus and I did discuss the overlapping work issues with the ebXML Joint Coordinating Committee on several occasions.  I believe that OASIS continues to be committed to ebXML, but the May 2001 MoU with CEFACT is not very clear or helpful in defining the relationship, and OASIS does not believe that it has much ability to constrain or limit the actions of its various committees.  I am confident that OASIS will cooperate with whatever resolution the UBL TC itself reaches.  We felt the best approach was to take up the issue directly with the UBL team and its leadership.

I am hopeful that the discussions this week will result in joint work rather than continued parallel tracks.

Best regards    Jamie Clark
