Consider the following statements made in eWeek newspaper from Ziff Davis
Aug 7, 2000:
"by next year, 70 percent of all B2B transactions executed on the Web will
be done using XML, Gartner Group Inc. predicts"
please note .. it says .. web . second .. it does not relate this to the
total number of B2B transactions from all sources.
EDI vs. XML
EDI
1. Optimized for compressed messages
True
2. Requires dedicated EDI server costing $10,000 to $100,000
False
3. Uses value-added network
False
4. EDI message format can take many months to master
False
5. Requires C++ programmers
False
6. Machine Readable
XML
1. Optimized for easy display and programming
Not necessarily true
2. Requires Web server costing up to $5,000
False
3. Uses existing internet connection
IF one exists
4. XML message format can be learned in hours
False .. from what source
5. Requires JavaScript, Visual Basic, Python or perl script writers
True
6. Human and machine readable
Only when translated
"My suggestion is to limit investments in EDI and explore ways to use XML.
EDI will probably be around for the next 10 years though, " [Gartner's] Knox
said.
Does this guy do anything but write !~?? Ziff-Davis is only a publisher ..
not necessarily an expert on anything
I guess this proves it conclusively :) - EDI is dying.
What in the above .. gives you that impression ......?? if anything.??

Subject: Re[2]: Is the Internet/XML Going to Kill EDI?
I see that my instincts about EDI versus EDI/XML or just XML are pretty
close to the target....I am just starting to look at XML and it seems
cumbersome, but not difficult. I believe that W3C is in the process of
developing 'schemas' to mirror X12 standards, that is for related
elements
in a segment, but that seems a ways off.
So of the two 'camps' or schools of thought, I believe that EDI will
not be
replaced by XML, but useful in implementing trading partners more
quickly
if they don't have/need EDI in the background.
Thanks for your note...
Chris

List-
I've been a lurker on this list for some time and I
would like to make a comment about the exitement
regarding XML and its ability to "replace" EDI.
Roy makes a good point of dividing the e-commerce
connection into three areas, Medium, Syntax, and
Semantics, so I will use these terms.
The Internet *can* replace the Medium, which is now the
expensive VAN's (Value-Added Networks). For that
matter, people can e-mail or FTP EDI documents. So
long as the receiver is sophisticated enough to receive
it, the Medium can change at any time, regardless of
whether EDI is used or not. In many cases two parters
with massive EDI exchanges elect to use an alternate
method because the convenience of the VAN cannot offset
its significant dollar costs.
Regarding the Syntax and Semantics, XML *can* replace
EDI's current syntax and semantics. But, to what
discernable benefit?
An XML Semantics *can* be a viable replacement if not
an improvment upon EDI. XML can use document format
descriptions that are more easily read by a human, so
that is one benefit.
However, the problems which plague EDI will plague its
successor, no matter what the form.
One of the biggest problems in setting up EDI systems
is what Roy refers to as the "Semantics". Namely,
with EDI every company in effect uses its own format
and its own unique business rules. Take for instance
an EDI 850 Purchase Order. Given ten companies, there
will most likely be ten different variations. An
interface written to accept one EDI 850 will not be
able to accept another.
EDI uses the ANSI X12 Standard. However, this
standard could be compared to the standard of the
English language. The words and vocabulary are
defined, yes, but tell ten people to write a letter
and each will format and phrase it differently. And
they do.
The current EDI exchange has an advantage that the
"Syntax" is already defined. XML must now go through
this growing phase, and in the end it will probably
resemble the ANSI X12 standard with better
descriptions.
The only way the inherent e-commerce problem can be
solved would be if companies somehow agree to use a
common format for their documents. This does not seem
practical, however, no matter how attractive the
concept.
EDI or any replacement in effect connects two
businesses with unlike ERP's and unlike business
rules. Each ERP will have its own special tehcnical
requirements, and business plan has special needs
which other business may not use or anticipate. These
things contribute to giving EDI a bad reputation, but
its replacement will inherit the same.
I would encourage any and all responses to this post.
Sincerely,
Jim Szyszko
EDI Contractor
