Hello this does not sum the newly entered goals with the one already saved
in my owl file. Every time I enter new goal (integer value), new data is
saved and does not added(sum) with previously entered values.
* int goalsss = soln.getLiteral("goal").getInt() ; //return integer value*
*int totalgoals=goalsss+totalgoals; // total goals initial value is 0*
*Literal p = model.createTypedLiteral(totalgoals);*
* team.setPropertyValue(goals, p);// here goals is property name*
OntModel model=ModelFactory.createOntologyModel();
InputStream in =FileManager.get().open("D://ont/soccer.owl");
if (in==null) {
throw new IllegalArgumentException( "File: " + " not
there");
} model.read(in,"");
String ns="http://www.semanticweb.org/neha/ontologies/2016/6/
untitled-ontology-11#";
OntClass team = model.getOntClass(ns + "Team");
OntProperty goals=model.getOntProperty(ns+ "Goals");
//Goals are entered by admin, so I want to sum the newly entered
//goals with previous stored in ontology.
//This is why I need integer values from these properties.
SELECT *" +
" WHERE { ?x rdf:type ont:Team . ?x ont:Goals ?goal )
";
Query query = QueryFactory.create(queryString) ;
QueryExecution qexec = QueryExecutionFactory.create(query,
model);
ResultSet results = qexec.execSelect() ;
while(results.hasNext()){
QuerySolution soln = results.nextSolution() ;
int goalsss = soln.getLiteral("goal").getInt() ;
int totalgoals=goalsss+totalgoals;
Literal p = model.createTypedLiteral(totalgoals);
team.setPropertyValue(goals, p);// here goals is property name
