There is much more to GOS than just the portal effort. There is considerable
work being done on schema mapping to address various semantic issues. The
schema mapping is being done through cross organizational work groups. I do
not want to start another OGC flame fest, but I thought that the List should
realize that the GOS portal is the front end "technology part". There is
also considerable effort "behind the scenes" dealing with the data model,
institutional, and organizational issues.

That's exactly what I said. All I questioned was the uniform orthodoxy
that the end result of all this talk about open interfaces was actually
going to improve the overall ability of people to work with integrated
data. A cascaded WMS service (might) look pretty, but you cannot
answer many (any) analytical questions with it. If organizations
remain unwilling to provide access to actual data, it is irrelevant
whether they fail to provide access via WFS or fail to provide access
via an FTP site full of SDTS files. My point is that the technology is
not the hard part, yet it receives for more attention than the actual
problem, which is organizational intransigence. In some cases, it is
being substituted for solving the actual organizational problem ("aha,
we can 'publish' our data via WMS and then people can look at it
without actually touching it"). Is a half measure better than no
measure? It depends on whether the half-measure is relieving the
pressure to solve the whole problem.
Do you see?
