Bug ID: 370443
           Summary: jp2 metadata: Unrecognized UUID EXIF box
           Product: digikam
           Version: 5.2.0
          Platform: MS Windows
                OS: MS Windows
            Status: UNCONFIRMED
          Severity: major
          Priority: NOR
         Component: Metadata


I work with digiKam and ShowFoto 5.2.0 on a Win 7 system.

In order to come to know ShowFoto I played with it. So I also opened a *.jpg
(with Exif metadata) image and stored it as *.jp2.

Now Exiftool cannot read the Exif metadata written by ShowFoto. It reports :
Unrecognized UUID EXIF box.
Also XnViewMP - which uses an Adobe toolkit for metadata - does not read the
metadata of *.jp2 file.

I asked Phil Harvey, the developer of Exifttol, and he stated:
"Digikam has apparently written a JPEG EXIF header in front of the TIFF header
(six extra bytes: "Exif\0\0"), so ExifTool gives the warning and can't process
the EXIF.

>From interoperability point of view this is a very bad situation.
Because Exiftool and XnViewXP write a "common format" of the uuid tag, I guess
the problem could be on digiKam side.

Please help to solve the major interoperability problem.
Thanks in advance
Best regards
