The purpose of this task is evaluating if Virtuoso can serve as alternative to Blazegraph as a backend for Wikidata Query Service. We need to check:
- Whether it is feasible to install Open Source version of Virtuoso in our production environment
- Whether is is possible to load Wikidata SPARQL dump into Virtuoso and efficiently run queries
- Which functionality differences exist between current implementation of WDQS and Virtuoso and whether it is possible/feasible to bridge them and what it would cost
