> Key: JENA-2075
> URL: https://issues.apache.org/jira/browse/JENA-2075
> Project: Apache Jena
> Issue Type: Bug
> Components: Core
> Affects Versions: Jena 3.17.0
> Reporter: Claude Warren
> Assignee: Claude Warren
> Priority: Major
> Fix For: Jena 4.0.0

>
> I think the issue is in the Seq.set() method but the if the example below is
> executed the results are variously boolean values or strings representing
> boolean values.
> Code:
> {code:java}
> import org.apache.jena.rdf.model.Model;
> import org.apache.jena.rdf.model.ModelFactory;
> import org.apache.jena.rdf.model.Seq;
> public class SeqTest {
> public static void main(String[] args) {
> Model m = ModelFactory.createDefaultModel();
> Seq seq = m.createSeq();
> seq.add( 1L );
> seq.add(2, 2L );
> m.write(System.out, "TURTLE");
> seq.set(1, 1L);
> m.write(System.out, "TURTLE");
> }
> }
> {code}
> Result:
> {code:java}
> [ a <http://www.w3.org/1999/02/22-rdf-syntax-ns#Seq> ;
> <http://www.w3.org/1999/02/22-rdf-syntax-ns#_1>
> "1" ;

> "1"^^<http://www.w3.org/2001/XMLSchema#long> ;

> "2"
> ] .
> {code}
> The Collection.add() code and the Seq.add() methods both insert string
> representations for the long values. The Seq.set() method on the other hand
> places a typed literal in the graph.
> Personally I would rather see the typed literal but I don't know that the
> standard says.
