Base URI in turtle output

Hi all,

I can't manage to produce Turtle output with a base URI from a Jena model.
The following piece of code...

---
Model model = ModelFactory.createDefaultModel();
model.add(
                model.getResource("http://mydomain/resource1/"),
                model.getProperty("http://mydomain/property1"),
                model.getResource("http://mydomain/resource2/")
);
model.getWriter("TURTLE").write(model, System.out, "http://mydomain/");
---

produces :

---
<http://mydomain/resource1/>
      <http://mydomain/property1>
              <http://mydomain/resource2/> .
---

while I expected :

---
<resource1/>
   <property1>
       <resource2/> .
---

Any idea how I could produce the above output ?

Many thanks in advance,

Damien

Hi Damien,

The Turtle writer does not use the base when writing.  It could do, and 
write a @base declaration, but it doesn't.

It does use prefixes, where possible.

or just

model.write(System.out, "TURTLE");
