Mark Proctor commented on JBRULES-46:
-------------------------------------
We have something prototyped in trunk, but it's not exposed in the language yet. We
are probably going to hold off from pushing this live until we update to a new algorithm
around collection-oriented match, which won't have the recursion issues. We have
started to spec out what the language would look like;

Prolog Style Query Based Backward Chaining
------------------------------------------
Key: JBRULES-46
URL: https://jira.jboss.org/browse/JBRULES-46
Project: Drools
Issue Type: Feature Request
Security Level: Public(Everyone can see)
Reporter: Mark Proctor
Assignee: Mark Proctor
Forward Chaining means that facts are asserted and propgated forward throughout the
network, during forward propagation matching takes place which results in rules being
fired - the rules are event based, in that they are fired in response to changed in the
working memory.
Backward chaining is query based. Rules attempt to fire first but do not have the
necessary matched facts, so facts are pulled in from an external source.
