Jeff,
Seemed to have hit a real nerve with you. I noticed that you were one of
the main participants in the demo you point me to. Could it be that this
demonstration was not so much of an independent performance test, but rather
a "critical-mass" building effort, coupled with a justification of existence
effort, that does not truly examine the bits and bytes level performance of
the combined OGC technology under real LIVE conditions.
You say that "factors like map generation, response time etc. are not a
factor of the specification, rather the vendor implementation of the spec":
this may be true to some extent, but are there really so many possibilities
of implementing a "standard" that it would manifest itself in significant
differences between vendors ? If so, whats the point of the "standard"?
Granted, some vendors never hear the message and the voices of discontent,
that doesn't keep them from becoming industry behemoths, in spite of bad
performing products. So, this argument by you should not be used as a basis
to judge the standard itself should it ?
I did not assert that no testing has been done, I challenged those who have
done testing to make it public. The real interesting stuff, not the summary
conclusions that "we tested it, it works fine". What were the bit by bit
items tested, under what conditions or scenarios, what network parameters
existed, what layers were used, how many different formats, file sizes, were
they vectors, rasters, a single shapefile or a Geodatabase, an Oracle
instance that resides inside an ERP database, what scales, what other
metadata is involved. Simply stating that "interoperability testing" has
been done does not satisfy the challenge. So what. No one is arguing that
they are not "interoperable", that's almost irrelevant. How they scale and
perform under would-be real-life commercial and/or other conditions is the
real test.
You wrote "Or, we could just accept a simple fact. OGC specifications work.
They have been proved time and time again and they are now being used to
support geospatial enterprises." Why on earth would we want to just
"accept" something that is arguably a "fact". This is a dangerous, if not
irrational direction to consider. If you truly believe that, why not just
simply accept the FACT that the ESRI data model is the de facto
international standard, and all other formats should be encouraged to become
interoperable with that data model, and live with whatever performance
pre-dated OGC? I mean really, why be bothered and distracted by all this OGC
effort to essentially dilute ESRI's leverage, and just acquiesce to ESRI and
work on making it the best it can be for all constituents?
Does OGC WMS or any other specification do anything for the non-internet-GIS
user ? I don't think so, and as such, I would again assert that the relative
effort of OGC and its members on such a small % of actual GIS work, that it
is grossly disproportional in its influence on the GIS industry. Why not
focus on true enterprise GIS interoperability first, and then simply take
whatever is accepted as success and move that to the internet.
I have a more generalized questions for anyone from OGC or simply anyone:
When will OGC consider that it's mission is accomplished ? If the ultimate
evolution of OGC is not "extinction" then we should all be asking ourselves
why not ?
Thanks.
Anthony
