openCMIS: Creating a relationship

Session interface provides below methods to establish a relationship between two cmis objects.

ObjectId createRelationship(Map<String, ?> properties);

ObjectId createRelationship(Map<String, ?> properties, List<Policy> policies, List<Ace> addAces,List<Ace> removeAces);

How to create a relationship?

         private static ObjectId createRelationShip(Session session, String sourceId, String targetId){

                  Map<String, Object> properties = new HashMap<String, Object>();

                  properties.put(PropertyIds.NAME, "a new relationship");

                  properties.put(PropertyIds.OBJECT_TYPE_ID, "CrossReferenceType");

                  properties.put(PropertyIds.SOURCE_ID, sourceId);

                  properties.put(PropertyIds.TARGET_ID, targetId);

                  ObjectId newRelId = session.createRelationship(properties);

                  return newRelId;

         }
