[rules-users] Integrate Fusion into Guvnor

[Andargor]

This may or may not answer your question, but with regards to #2, I've been
easily able to convert my project based on Facts to Events by simply adding
this to one of the DRL files (I used drools.package):

declare NumericFact // This is an already defined proper Java class
	@role( event )
	@timestamp( date ) // property defined in class with getter and setter for
my needs (historical data)
	@expires( 365d ) // for my needs
end

And in my code to process streamed events:

KnowledgeBaseConfiguration config =
KnowledgeBaseFactory.newKnowledgeBaseConfiguration();
config.setOption( EventProcessingOption.STREAM );
kbase = KnowledgeBaseFactory.newKnowledgeBase(config);

Note that facts have to be inserted chronologically with STREAM.

HTH (perhaps)
