Re: Summary of XML Datatypes as required for B2B applications

["Tim McGrath" <tmcgrath@tedis.com.au>]

Well!  we thought it was only us.

Coincidentally, I have recently been asked by the ebXML sub-Group of the Australian CEFACT Management Committee to voice similar concerns.

Whilst i understand the thread under discussion originates from the XML/EDI Group List, it has some application to the processes within ebXML as well.

As yet, it has been unclear from the core components group how or when the semantic knowledge of 'heritage' EDI methods (e.g. EDIFACT) will be incorporated into this initiative.

I suspect, there are a considerable number of persons with appropriate knowledge and experience in solving many of the semantic and structural issues facing the group who are wondering how to contribute to this process.

The statement in the Core Componenents section of the ebXML Requirements Specification is:

> ? Use semantics solutions that accommodate currently defined accredited EDI semantics where they add value

- are there processes in place to bring this about?

Ian,

I think you have voiced my concerns here.  But what I suspect will happen is
that most of the "new" efforts being started now are primarily through
ignorance of the value of traditional EDI dictionary content.  These new
efforts will recreate and remodel until they find that their efforts fall
short of the universal need, then they will have no choice but to look at
the real world of EDI and integrate the EDIFACT and other data dictionaries
into their models.

IMHO: What is happening here is that most of these efforts are trying to
differentiate themselves from traditional EDI rather than integrating
themselves into the vast effort already expended to create the standards
already in place.  Then by manipulating the statistics, making the
e-commerce community believe they have a solution.  Their solutions may work
for a small part of the total EDI picture, but every time I take a look at
them, find them lacking many of the requirements for real-world, universal
EDI.  But I could be wrong.

Oh William, how right you are!  The EDIFACT dictionaries (and the rest) have
evolved through years of consideration of real user needs; it is not a big
deal to convert the essential semantic content of these dictionaries into a
different syntactic environment.  This was exactly the intent behind EDML.
The EDML proof of concept work demonstrated a means of transferring semantic
content (ie data dictionaries) developed for one syntactic message structure
into a quite different syntactic structure.  So to my mind an obvious way to
accelerate the development of XML-based ecommerce would be to exploit the
EDIFACT (and other) data dictionaries. But right now I don't have much
confidence that the good bits of EDIFACT, X12, HL7, etc will actually be
exploited.  It seems perhaps, that in rejecting the syntactic structures of
"traditional" EDI the semantic baby is being thrown out with the bathwater.

Best regards

Ian
