//  more than XML.  The NewXmp method returns an XML document with
//  the standard XMP boilerplate.
xml := xmp.NewXmp();

//  Add some properties...
success := xmp.AddSimpleStr(xml,'Iptc4xmpCore:Chilkat','Blah blah');
//  If you wish to view the XML, save it to a file and review it
//  with a text editor:
success := xml.SaveXml('newXmp.xml');

  begin
    ShowMessage(xml.LastErrorText);
    Exit;

//  To add the XMP to the JPG (or TIFF), simply load the JPG,
//  append the XMP, and save:
success := xmp.LoadAppFile('scream.jpg');
