If I try to merge properties to resource I usually use the resource URI, without any URI how can I refer to the blank resource. Or maybe there is an official URI for than blank object but could find it anywhere. Where is this defined? I wasn't able to figure out how to write such instance. Cheers Didier PH Martin
