The Dominion Rules Licence (or DRL) is the open gaming licence under which the Dominion Rules role-playing game system is distributed.

These provisions resemble those found in many open-source licences.
It was under this version of the DRL that Dominion Rules 2.0 was released in 2002.
DRL v. 2.0 is the version under which Dominion Rules 3.0 was released in 2008.
