Horizon

Transactional system that defines a set of primitive and composable concepts. It is inspired by Finite State Grammars.

ABSTRACT

Finite State Transactional Grammar. I don't know if I made up this term, so I won't claim to have invented this, but I'm running with it. What is sketched here is a transactional system inspired by finite state machines, finite state grammars, rule engines, map-reduce algorithms, functional programming (namely Clojure and LISP), business intelligence, and the rubygem Hero.
