GitHub repository: Buchhold/SparqlEngineDraft
Primary language: C++
Description: Basic (no full language support) but highly efficient SPARQL engine. To be extended to support Semantic Full-Text Search (see http://broccoli.cs.uni-freiburg.de/demos/BroccoliFreebase/) in a standard SPARQL-like fashion. That follow up extension will feature a proper license and encourage collaboration eventually. If you're interested in using code of this project, please just contact me.
