Quoting "Bullard, Claude L (Len)" <firstname.lastname@example.org>:
> It's called the complexity moat theory of
> constraining competition. Serious players
> believe in it and it always fails.
> GJXDM hasn't been proven on the ground yet.
> We use it for exchanges and given some smarts,
> it works, but it is deuce difficult to
> interpret when getting started. It isn't
> exactly a train wreck; more like a jammed
> up station. I think it varies in value
> depending on where you apply it.
> There is user community involvement. The
> trouble is likely having a lot of cooks with
> limited experience in markup design and also
> a need to follow the dictates of the XML Gov
> group that made the w3c holy before getting
> experience with the technologies. Whatever
> the customer wants, the customer gets. No
> sales guy causes contention when it gets
> to the down select. So money follows fashion.
> Also, some of the public safety vendors who
> had good running schemas for their systems
> hoarded them. Mine was one so I can't be
> too critical because the charge can be justly
> made that we sat the design phase out with
> the motto 'if they design it, we'll code
> to it'. Our guys had their heads squarely
> in the 80s and missed the web revolution
> of community effort and thought leadership.
> It was a terrible mistake. We made ourselves
> profitable again, but like a swimmer in the
> middle of a storm failed to realize that getting
> our heads above water for a breath didn't mean
> we weren't drowning.

> GJDXM is a classic train-wreck.
> The scary part is people build these schema
> without even determining the use cases. We're back to my - 'oh all we need
> a schema' rant again.
> So when the GJDXM people did actually stop to ask user communities what they
> wanted - they realized that there was no way that GJDXM can be deciphered
> purposed to provide that.
> Solution - instead of using CAM - let's invent our own 'CAM'.
> Sometimes you just shake your head. But full credit to them for continuing
> get funded for all this - someone must believe they have all the right
> Oh well.
> p.s. fighting complexity is a tough battle everywhere - not just OASIS.
> vendors thrive on complexity - since they figure only their vast team
> can figure out the implementation details then. Automatic lock-in. Also -
> something is inherently simple - why hire legions of consultants? So "the
> system" has a vested interested in perpetuating schema - oops - I meant
> complexity ; -)
