ViziQuer Data Schema Store

Load a schema into ViziQuer

Introduction This page provides Linked Data endpoint schemas. The schemas are obtained by examining their structure, with possibly minor manual adjustments.
The schemas can be loaded into ViziQuer tool projects ('Import VQ Schema' button) and used for visual query composition over these endpoints.
