ClioPatria is a SWI-Prolog application that integrates SWI-Prolog's the SWI-Prolog libraries for RDF and HTTP services into a ready to use (semantic) web server. The core server has an integrated package manager that allows distributing and using add-on libraries: CPACK.
The development of ClioPatria started within the MultimediaN project, where it formed the core of the a semantic search demonstrator that won 1st price in the ISWC2006 application contest . With the current ClioPatria, we stripped the functionality to the basics and provide the CPACK system for extending it. We intend to continue with the development for a long time.
