At least exif tool displays the folllowing  metadata, but this metadata is not
displayed in the metadata tab:

If I save a jp2 picture with digikam, then the metadata is displayed. But if I
create a jp2 for example with "convert -depth 14 -quality 80 -resize 10%
img.jp2 img_small.jp2" then the resulting picture does not show up any
metadata. I attach this resulting picture to this bugreport.
