Re: BSI in a Nutshell
I must confess that I feel like strangling whoever it was who brought this
dead horse back to life. Still, I can't restrain myself from taking a few
more whacks at it to put the zombie back into the coffin.
From a technical perspective, BSI could work as well as any of the other
approaches to data exchange. From a market perspective, it was DOA when
first introduced, despite the protestations of its (few) proponents. It is
even deader now with the emergence of XML.
From my perspective, the fly in the ointment with BSI was that its
proponents always seemed to focus on the elegance of BSI technology and
trivialize the problems in coordinating business processes and data
semantics. These remain with us regardless of the underlying
technology. Notwithstanding the work done by groups such as UN/CEFACT,
RosettaNet, and ebXML, I have yet to see an approach that truly solves
these problems.
RIP BSI.
Long live EDI and XML (and market pragmatism)
Cheers,
Mike
