Code examples

Java

For java we recommend the Jena Framework. 

import com.hp.hpl.jena.query.Query;
import com.hp.hpl.jena.query.QueryExecution;
import com.hp.hpl.jena.query.QueryExecutionFactory;
import com.hp.hpl.jena.query.QueryFactory;
import com.hp.hpl.jena.query.QuerySolution;
import com.hp.hpl.jena.query.ResultSet;

public class javaCodeExample {

	public static void main(String[] args) {
		String sparqlQueryString = "SELECT * WHERE {?s ?p ?o} LIMIT 10";
		Query query = QueryFactory.create(sparqlQueryString);
		QueryExecution queryExecution = QueryExecutionFactory.sparqlService("http://sparql.wikipathways.org", query);
		ResultSet resultSet = queryExecution.execSelect();
		while (resultSet.hasNext()) {
			QuerySolution solution = resultSet.next();
			System.out.print(solution.get("s"));
			System.out.print("\t"+solution.get("p"));
			System.out.println("\t"+solution.get("o"));
		}
	}
}

php

For php we recommend the arc2: Easy RDF and SPARQL for LAMP systems

R 

   library(rrdf)
   sparql.remote(
     "http://sparql.wikipathways.org/",
     "SELECT DISTINCT ?p WHERE { ?s ?p ?o }"
   )

Bioclipse

The below code works in both the JavaScript and the Groovy console: 

   rdf.sparqlRemote(
     "http://sparql.wikipathways.org/",
     "SELECT DISTINCT ?p WHERE { ?s ?p ?o }"
   )

SPARQL from the command line

For quick and easy querying, we recommend to use curl (Linux and OS X) 

curl -F "query=SELECT * WHERE {?s ?p ?o} LIMIT 10" http://sparql.wikipathways.org
