XMP/RDF help needed

Hi Guys

I am playing with Warrens patch, and using Gabriels GThumb tag import
patch as a template. So far so good. I have managed to import the normal
keywords (the ones F-Spot stores), plus some normal photoshop/iView
stored parameters. I am stuck on some other tags...

Do anyone have any clue of how to import tags in XMP/RDF?
I have done the following, 


> 			if (xmptags_sidecar)
> 				xmpfile = new XmpFile(System.IO.File.OpenRead(xmptags_file));
> 			else {
> 				JpegFile jpegfile = new JpegFile(xmptags_file);
> 				JpegHeader jpegheader = jpegfile.Header;
> 				xmpfile = jpegheader.GetXmp();
> 			}
>

> 
> 				string stmt_obj_str = stmt.Object.ToString();
>

> 				if (!found_keywords)
> 					switch (stmt.Predicate.ToString()) {

> 							break;
> 						case "http://ns.adobe.com/photoshop/1.0/Country"; :

> 							break;

> 							break;
> 						default :
> 							break;

But can not seem to import these tags...

If you wonder, I am using this XMP sidecar file as my sample.
