There is a public SPARQL endpoint over the DBpedia data set at:

http://DBpedia.org/sparql

The endpoint is provided using OpenLink Virtuoso as the back-end database engine.

You can ask queries against DBpedia using:

• the Leipzig query builder at http://querybuilder.dbpedia.org;
• the OpenLink Interactive SPARQL Query Builder (iSPARQL) at http://dbpedia.org/isparql;
• the SNORQL query explorer at http://dbpedia.org/snorql (does not work with Internet Explorer); or
• any other SPARQL-aware client(s).

There is a list of all DBpedia data sets that are currently loaded into the SPARQL endpoint. This may not always include all available DBpedia data sets.
