Its a description logic, is all, rendered into a barbaric notation, and with a botched interface to a triple-store mechanism (for which botching I bear part of the blame, to be honest) and burdened with an ill-defined commitment to using URIs as universal identifiers in some as-yet-still-unspecified way. > - I hope that this will not come back to haunt them during AFSAB >reviews.

Endorsing DAML+OIL is something else again, however. > 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...

You know its not considered good form to threaten the servants, even if they do annoy you sometimes with their talkative ways.
