- You might want to check out YAPS, a production rule language we sell
- which provides rule-based programming. The syntax is simpler than
- OPS5, but YAPS is more powerful in that it provides the YAPS-KB class
- which you can include in your CLOS classes. Then instances of your
- classes have their own knowledge bases (facts and rules) attached to
- them. So, you associate with each objects the rules and facts that
- pertain to that object. This turns out to be a good way to modularize
- your rules.
-
- If you're interested in YAPS, send me your address, and I'll send you
- literature.
