Parliament™ is a high-performance triple store designed for the Semantic Web. Parliament™ is a trademark of BBN Technologies, Inc., and is so-named because a group of owls is properly called a "parliament" of owls.

Parliament was released as an open source project under the BSD license at SemWebCentral in June, 2009.

Parliament implements a high-performance storage engine that is compatible with the RDF and OWL standards. Parliament is typically paired with a query processor, such as Sesame or Jena, to implement a complete data management solution that complies with the RDF, OWL, and SPARQL standards for data representation, ontology, and query, respectively.
