LODStats: a statement-stream-based approach for gathering comprehensive statistics about RDF datasets

LODStats is a statement-stream-based approach for gathering comprehensive statistics about datasets adhering to the Resource Description Framework (RDF). LODStats is based on the declarative description of statistical dataset characteristics. Its main advantages over other approaches are a smaller memory footprint and significantly better performance and scalability. We integrated LODStats into the CKAN dataset metadata registry and obtained a comprehensive picture of the current state of the Data Web.
