(Apologies for cross-posting) Hi all, we are happy to announce the release of the Linked Open Data Integration Benchmark (LODIB), which has been devised for comparing the expressivity as well as the runtime performance of Linked Data translation systems. It was developed by a collaboration between the University of Sevilla and the Web Based Systems Group. The benchmark was devised by looking at a sample of entities from the LOD Cloud. From this sample we extracted a catalog of fifteen data translation patterns and survey how often these patterns occur in the example set. Based on these statistics, we designed our benchmark that aims to reflect the real-world heterogeneities that exist on the Web of Data. The benchmark also comes with a data generator in order to test data translation systems at differet scales. We applied the benchmark to test the performance of two data translation systems, Mosto and LDIF, and compare the performance of the systems with the SPARQL 1.1 CONSTRUCT query performance of the Jena TDB RDF store. LODIB is publicly available at: http://lodib.wbsg.de Best regards, Carlos R. Rivero (University of Sevilla), Andreas Schultz (Freie Universität Berlin), Christian Bizer (Freie Universität Berlin) and David Ruiz (University of Sevilla)
