How to use the engine with OpenStruct object about wongi-engine HOT 4 OPEN

The way I've been doing this sort of thing is like:

object_list.each do |one_object|
    engine << [one_object, 'is', OBJECT_TYPE]
    engine << [one_object, ATTRIBUTE1 << one_object.ATTRIBUTE1]
    engine << [one_object, ATTRIBUTE2 << one_object.ATTRIBUTE2]
    ...
end

and then rules something like

rule "object1 box == object2 box" do
  forall {
    has :Object1, 'is', OBJECT_TYPE
    has :Object2, 'is', OBJECT_TYPE
    has :Object1, 'box', :OneValue
    has :Object2, 'box', :OneValue
  }

Of course, if you're only using the rule engine on one type of thing, you can leave out the type step/rule.

If there's a better way, I'd love to hear about it :-)

There isn't. If you want to use structures, you must decompose them into triples.

Although having some sort of automatic translation is an interesting idea.

I've been slowly working towards this, actually.
