SPARL Lab was created to encourage experiments with the public SPARQL endpoints of ZBW Leibniz Information Centre of Economics, and with a few other datasets. Queries can loaded from our GitHub repository (or others) and edited by everbody.
Our public SPARQL endpoints are mostly based on Fuseki2, part of the Apache Jena project, and on the YASGUI libraries for the user interface. For more information on Fuseki, YASGUI and SPARQL Lab see below.
We currently offer endpoints for the following datasets. General queries for exploring the endpoints can be found here.
Data from the GND Linked Data Service.
Endpoints with multiple versions of a dataset and queries to compare them are referenced in the skos-history project.
