Cory, (01)
A typical problem with government designed and managed architectures is that
they have the potential to represent a lowest common denominator (LCD)
approach in order to accommodate the interest of all the candidate
participants. The resultant LCD architectures are so vague that they still
allow many non-interoperable applications to be developed and almost always
contain relatively easy to obtain provisions for exceptions. It seems that
the one architectural standard that has best held up over a number of years,
gracefully evolved and truly supported broad interoperability is the World
Wide Web architecture. It was not designed or managed by the government.
Also, it is not proprietary. So, it may be useful to focus on ways to extend
the proven WWW model, via W3C processes, to accommodate the CDSI
requirements before branching out to seriously consider other less tried and
proven approaches. (02)

Brad,
We have been thinking along similar lines but I submit the government has to
own their architectures, only they have the cross-cutting view (or should
have). Contractors can help build these, but the architecture asset (as the
expression of the enterprise, enterprise needs and solutions - business or
technical) has to be put into the acquisition cycle. Systems then need to
be built to that architecture is an executable, testable way. Those
architectures have to STOP being "for a system" and be "for the enterprise".
SOA makes a great model for these architectures - separating concerns and
providing the boundaries to build to. The semantic technologies can help
here to join and bridge architectures, but you are absolutely correct that
the core problem is not technical.
