Subject: Re: The initial ebXML business vocabulary - A call for a listofcandidates

Dear John,
You are welcome to stay with the old and I'll take the new :).
I think you will find extending traditional EDI to work with smaller and
medium companies much harder than keeping the EDI investement where it works
(within VANs and within fortune 1000) and using new systems to work with
trading partners that are not going to be on EDI. I believe you will see
that in the next 4 to 5 years a lot of big EDI users are planning to
implement part or all their business automation over XML. I think I read
that in some report very recently. EDI will be around no doubt but so are
mainframes. They run and they are OK but they are not a solution for
everything and certainly not the solution for the internet.
