ViziQuer: A Tool to Explore and Query SPARQL Endpoints

  • Martins Zviedris
  • Guntis Barzdins
Part of the Lecture Notes in Computer Science book series (LNCS, volume 6644)


The presented tool uses a novel approach to explore and query a SPARQL endpoint. The tool is simple to use as a user needs only to enter an address of a SPARQL endpoint of one’s interest. The tool will extract and visualize graphically the data schema of the endpoint. The user will be able to overview the data schema and use it to construct a SPARQL query according to the data schema. The tool can be downloaded from There is also additional information and help on how to use it in practice.
