by modal operators, what do you mean? Do you mean modal logic? http://en.wikipedia.org/wiki/Modal_logic
Are you looking for temporal logic support, or modal logic support. I'm not an expert on modal logic, but many people have tried to implement a general purpose modal logic engine. to my knowledge there aren't any commercial or successful modal logic rule engines. Proper support for modal logic is very complex, so it's not a trivial task. peter On Tue, Jul 29, 2008 at 10:14 AM, Martijn Tromm <[EMAIL PROTECTED]> wrote: > Hello, > > Has anybody ever attempted to add modal operators to the Jess language?
