(Tool description last modified on 2011-01-9.)


Parliament is a high-performance triple store designed for the Semantic Web. Parliament was originally developed under the name DAML DB and was extended by BBN Technologies for internal use in its R&D programs. Parliament was released as an open source project under the BSD license in June, 2009. Parliament's rule engine currently implements most of RDFS inference plus selected elements of OWL-Lite. Parliament is a triple store and a rule engine, but it does not include a query processor. Therefore, it is typically paired with a third-party query processor, such as Jena or Sesame. "
