relationships get complicated fast

Remember that a triple CSec has a relationship ("wife") and a topic (the wife).

Now that relationship will probably be of type relationship, which would be a special kind of topic, I'm guessing. And it would need some DEnts to indicate if the relations ship is transitive and/or symetric. I.E. If George is my brother then I am George's brother. And if Henry is my brother, then George is Henry's brother. --brother is both transitive and symetric.

The isa relationship will also be a fun one, especially when applied to other relationships... brother isa relative, so Henry is a relative of George.

Now, how do we do that! :-)
