Rules

Jon Udell highlights a technology lost in the late 1980's "A.I. Winter", but which kind of hung around and is now coming back into its own. I'm a veteran of the A.I. Winter and was disappointed when very practical tools like KnowledgeCraft and GoldWorks were lost in the hype of those days. Looks like GoldWorks is still available.

Some more resources to add to Jon's list...

• CLIPS - the grandparent of almost all current rules engines, public domain, written in C with good integration possibilities to other languages.
• Business Rules Applied - a very good book that covers a wide variety of issues around the management of business rules.
