I guess I should have made it clear that this is my own personal (stupid?)
opinion, not an AF position.

As a potenial DAML +OIL user, but one who will probably not go that route,
here is my 2 cents worth.  Every new thing like DAML exits somewhere in a
tradeoff between academic elegance and practical utility.  From what I see
of DAML, it is way to far from utility and way to close to (attempted)


It seems DAML is re-fighting (and still not winning) the wars the KR
community has been struggling with for at least the last 20 years.




It is so good to see our Air Force researcher lab staff so open-mindedly
examining a new technology - I hope that this will not come back to haunt
them during AFSAB reviews.  I'd love to hear from John why he thinks that
DAML is not winning - I cannot remember another AI language that ever has
had so much public interest, web use, and moved into standardization by a
major body -- in fact, in hype we probably lag behind the old expert systems
days, but in acceptance we seem to be moving beyond and winning acceptance.
Perhaps the military seems to be moving slow (as usual), but the Web
Ontology Working Group includes such small companies as Intel,
Daimler-Chrysler, EDS, Fujitsu, HP, Intel, Lucent, Nokia, Philips
Electronics, and Unisys -- with a couple of other big players talking to me
about joining.  There's also a rumor around that IBM Research has included
Semantic Web-related work in their strategic plan -- in short, we're seeing
a positive interest that had not been seen in this way in the past (except
maybe for the expert systems days - which all these companies, and many of
the rest of the Fortune 500, are using regularly).  Perhaps John's message
helps explain why Air Force F-16s are flying with 240,000 lines of Jovial
code in their controllers and why the DoD is still maintaining that Corba,
not Java, is the language of the future...
p.s. John - you're lucky I'm not the PM anymore - if you sent a messgae like
the above when I was PM you'd be looking for another program to support.
