The download/registration form that the code was derived from is at: http://clarkparsia.com/pellet/download/pellet-2.3.0 This source code is only available here under the AGPL-3.0, as Clark & Parsia retain the copyright to the code so the license cannot be changed here: http://www.fsf.org/licensing/licenses/agpl-3.0.html If you want a commercial license you need to contact Clark & Parsia directly: http://clarkparsia.com/pellet/dual-license The deprecated Pellet DIG interface, any of the tests and CLI commands that relate to it have been removed. The test files that are required as resources for the pellet-test module are unavailable, so the relevant tests will fail until they are made available. If the pellet-query module fails to install due to an Out of Memory Exception, run maven using: MAVEN_OPTS="-Xmx1024m" mvn clean install
