[berezovskyi]

task.getExtendedProperties()
        .put(
                new QName(Oslc_cmVocabularyConstants.CHANGE_MANAGEMENT_VOCAB_NAMSPACE, "testedByTestCase"),
                new Link(
                        new URI("http://qmprovider/testcase/1"),
                        "Accessibility verification using a screen reader"));

produces:

  oslc_cm:testedByTestCase  "Link{to='http://qmprovider/testcase/1'; label='Accessibility verification using a screen reader'}"^^<java:org.eclipse.lyo.oslc4j.core.model.Link>;
