Not completly right !

The first way to backup metadata into PNG file are raw profiles, and digikam image editor support ImageMagick raw Exif/iptc profile to save EXIF and IPTC metadata ! 

Try this command line (with foo1.jpg is a file with Exif info) :

# convert foo1.jpg foo2.png
# convert foo2.png foo3.jpg

Now look the results into digikam or showfoto metadata tab ! foo3.jpg have the same EXIF info of foo1.jpg

The second way is chunk creation like photoshop does (i think). I study this way for the next release (later 0.9.0 issue).
