Parliament™ Introduction

Parliament™ is a high-performance triple store and reasoner designed for the Semantic Web. Parliament's initial development was funded by DARPA through the DAML program under the name DAML DB and was extended by Raytheon BBN Technologies (BBN) for internal use in its R&D programs. BBN released Parliament as an open source project under the BSD license on SemWebCentral in 2009. In 2018, BBN migrated the Parliament open source project to GitHub under the same license.

Parliament™ is a trademark of Raytheon BBN Technologies. It is so named because a group of owls is properly called a parliament of owls.
