Some may already know about this but still this is very interesting topic for those who are involved in degisning rule engines in conjunction with object modeling for very large complex systems.

some of you might have used OCL while integrated with XML based models, but its worth having a look at IBM autonomics.

http://www.research.ibm.com/autonomic/

this needs a bit of research before fully understanding it, but this is an intelligent system that has the ability to learn so it makes life easier for those who get involved in complex rules. processes and system behaviour will be intelligent and interactions will all be automated using this technique. I leave the rest for yourself to findout.

dig into IBM website and become familiar with autonomic computing.
