I don't think a UDDI ever required a centralized repository
even if some thought that to be the case. We tried that
sort of thing in the CALS era for DoD and it breaks down
quickly. No matter how smart we think we are or how
powerful be believe our imprimatur, unless we enable
disagreement as well as agreement, our power degrades
and our smarts become irrelevant. Keep a light hand
on the tiller.
Systems of communication have to be able to
dispense with intermediaries as soon as they quit providing
interpretive value. Communicating endpoints have to be
able to provide their own descriptions. Standardization
is not a form of autocratic government. It is simply a
way for aggregating aggreements to remain stable by
authoritatively and contractually obligating themselves.
The right is to choose the means to choose the means.
Smart designers and contract specialists scope agreements
in time and by the affected resources. UDDI lets you shop around
and as such, is little more than billboards on the information
superhighway (to use a now aging term). Discover via
UDDI, then negotiate.
None of this is rocket science or even particularly
abstract. It does relate directly to the constraints
placed on centralized authorities to enable interpretations
to evolve yet not destabilize the process of cooperation.
VWs thrive where aging parts are available. Hummers
thrive where you need a bit more protection from the
local environment. But most of the time, the better
solution is to buy a Ford. Parts, service,
and modern performance conform to the EPA regs,
insurance is not prohibitive, and it has a good
trade-in value. Or buy a Lexus if you can. :-)
Cars evolve. So do standardized semantics, but
only insofar as the choice of choices remains open.

UDDI is interesting, but I think the decentralized model will continue to
dominate. Even those pushing UDDI recognize that and offer specs and
toolkits for rolling your own discovery service on your own website with no
central repository involved.
