Klaus; I am happy to work with any consistent meta-data format that works and is practical. If XMP delivers the goods, that's great.
Viewed on Digikam: PNG XMP meta-data looks fine except that we are missing tag/title information. TIFF files look very bare in the meta-data area (no tags also) and are still unfortunately being written as 'tif' ... thus showing-up as RAW if the file is reloaded. JPG is fine in all respects except that I am not so gung-ho on the 8 bit lossy format.
