'''[[w:DBpedia|DBpedia]]''' [https://www.dbpedia.org/ (.org)] is a community effort to enable the web moving ''"Towards a Public Data Infrastructure for a Large, Multilingual, Semantic Knowledge Graph"''. | |||
Today the DBpedia '''[[w:data set|data set]]s''' contain a wealth of information structured into '''[[w:Ontology (information science)|ontologies]]'''. This [[w:structured data|structured data]] can be queried with [[SPARQL]] query language at their [http://dbpedia.org/sparql public DBpedia SPARQL endpoint]. | |||
DBpedia uses [[w:Virtuoso Universal Server]] to store and query the data. [https://www.w3.org/wiki/VirtuosoUniversalServer VirtuosoUniversalServer at w3.org] | |||
There are many methods how the DBpedia ontology and datasets could be used in the Consumerium implementation stage wiki. | |||
