Richard Cyganiak commented on JENA-51:
--------------------------------------
Upgrading to 2.6.4 fixed the problem. Sorry, should have tried that first.
Thanks for the help everyone.
(Good to see that jena.jar and arq.jar now have the version number in the
filename.)
> Turtle parser misses prefix declarations
> ----------------------------------------
>
> Key: JENA-51
> URL: https://issues.apache.org/jira/browse/JENA-51
> Project: Jena
> Issue Type: Bug
> Components: Jena
> Reporter: Richard Cyganiak
> Assignee: Andy Seaborne
> Priority: Minor
>
> Jena's Turtle parser doesn't capture @prefix declarations in the prefix
> mapping. Any triples are parsed correctly, but model.getNsPrefixMap() and
> friends show an empty prefix mapping.
> The N3 parser handles this correctly.
> ====== example code below =======
> import com.hp.hpl.jena.rdf.model.*;
> public class Test {
> public static void main(String[] args) {
> String s =
> "@prefix ex1: <http://example.com/1#>.\n" +
> "@prefix ex2: <http://example.com/2#>.\n" +
> "ex1:A a ex1:B .";
>
> Model n3 = ModelFactory.createDefaultModel();
> System.out.println("Parsing with N3 parser and printing
> prefixes:");
> n3.read(new java.io.ByteArrayInputStream(s.getBytes()), null,
> "N3");
> System.out.println(n3.getNsPrefixMap());
> Model turtle = ModelFactory.createDefaultModel();
> System.out.println("Parsing with Turtle parser and printing
> prefixes:");
> turtle.read(new java.io.ByteArrayInputStream(s.getBytes()),
> null, "TURTLE");
> System.out.println(turtle.getNsPrefixMap());
> }
> }
> ===== output ======
> Parsing with N3 parser:
> {ex2=http://example.com/2#, ex1=http://example.com/1#}
> Parsing with Turtle parser:
> {}
