It's currently a copy of the Mason ruleset. Where Mason focuses on letting the users create the world themselves, Deeds instead focuses on allowing world authors to set up enticing worlds with gameplay and stories. In contrast to Mason there are more features available to the world authors which allow for automatic creation of entities and so on.
