Wow. That is exciting, exciting, stuff.
Early on, I posited the potential need for a "knowledge mathematics"
that lets us abstract our knowledge and manipulate it. At the time,
I had no idea how much work had been done in Ontologies. Now this
comes along. A "mathematics of relationships" might well be the key
to abstract "understanding".
