Namespace and dynamic custom property access

Question

Hi,
I am trying to dynamically set Custom Property of KM Folder(Repository Framework) using the sample code which I found in one of the SAP site. I have modified the code for my requirement and this is how it looks. What I am not able to understand is the "namespace" part. Can anyone tell me what is this namespace field and how should I modify the code for it to get working.
RID rid = RID.getRID("/documents/TestFolder");
IResource resource = ResourceFactory.getInstance().getResource(rid, resourceContext);
String namespace = "http://com.sap.netweaver.bc.rf.sample/xmlns/sample";
String name = "PublishedOn";
IPropertyName propertyName = new PropertyName(namespace, name);
IProperty property = resource.getProperty(propertyName);
IMutableProperty mutableProperty = property.getMutable();
mutableProperty.setStringValue("10/12/2005");

They play the same role as namespaces in XML, RDF or WebDAV. You may want to read http://www.rpbourret.com/xml/NamespacesFAQ.htm.
