What about Agenda Groups?

Rule "pick group X"

when

Fact( attribute = "condition1" )

then

drools.setFocus("Group X")

end

Rule "pick group Y"

when

Fact( attribute = "condition2" )

then

drools.setFocus("Group Y")

end

Rule "Group X1"

Agenda Group "Group X"

when

Smurf( )

then

// Do something

end

Rule "Group X2"

Agenda Group "Group X"

when

Smurfette( )

then

// Something else

end

etc

Hi,

I am building a system where I would need to fire different sets of rules based on some attribute in the fact object.

Here are someways which I thought of, I was wondering if there was something better than that.

1) I could do this by creating different sessions based on the data attrbute (different sessions would have different rule packages based on the attribute)

or

2) Have all the rules fire (all the different sets of rules) irrespective of the attribute and have them insert fact new objects into the working memory. In the second round of rules, collect the (newly made) fact objects based on the attribute and take that action.

Thanks

Jai
