Summary: Execute SPARQL query
Operation ID: executeSparqlQuery
Auth: none

Execute SPARQL queries against the DBpedia knowledge graph via the root endpoint. This is the primary way to extract structured data from Wikipedia articles. The endpoint supports SELECT queries for tabular data, ASK for boolean results, DESCRIBE for resource descriptions, and CONSTRUCT for building new RDF graphs. Results are returned in SPARQL JSON format by default. Use this when you need to find specific facts across DBpedia's millions of entities - for example, finding all scientists born in a particular city, or retrieving labels and abstracts for a specific resource. The query parameter is URL-encoded and required.

Original spec description

Execute a SPARQL query against the DBpedia knowledge graph. Supports SELECT, ASK, DESCRIBE, and CONSTRUCT queries. Returns results in various formats including JSON, XML, CSV, and Turtle.

Usage Tips

- Always URL-encode your SPARQL query before sending - Use FILTER with langMatches() to get results in specific languages (e.g., FILTER (langMatches(lang(?label), "EN"))) - Include LIMIT clauses for large result sets to avoid timeouts - The default-graph-uri defaults to http://dbpedia.org if not specified

default-graph-uri (string, query, optional)

Default graph URI for the query
