There is an update to the axiomatic semantics. This includes minor fixes from comments we received.
Possibly more importantly, the publishing scheme for the axiomatic semantics has changed (thus if you have things
bookmarked, you should update them sorry).
Our semantics will always be published at
www.ksl.stanford.edu/people/dlm/daml-semantics

from there you will be able to get to the word, html, and text versions.
also, there is an abstract version in html
http://www.ksl.stanford.edu/people/dlm/daml-semantics/abstract-axiomatic-semantics.html

i have maintained the previously announced versions.
I also updated the ksl web page
www.ksl.stanford.edu/projects/daml to reflect the updates.

There will be a new release of DAML-ONT which will be called DAML+OIL as a result of the December meeting of the US/EU
joint committee.  After that is released, there will be another update of the axiomatic semantics.
