Description Nicofo 2013-10-21 21:12:03 UTC
Some EXIF tags (including concerning geolocation information (country name, city, landmark, etc...)) are not read by digikam (nor showphoto), while they are read by other software. These tags are Panasonic Makernote tags.

Example of such picture: see
  http://nicofo.tuxfamily.org/tmp/panasonic-tz40-GPSinfo.JPG

Example of software that can read these tags: "ExifView" (available on android). A screenshot of ExifView, with the missing information in digikam (Panasonic Makernote - City ; Country ; Landmark ; Location ; State) is given below:

In comparison, the Panasonic Makernote Exif tags are very poor in digikam:

Remark also that some tags are not correctly displayed in digikam, like:
- 'Baby Age' ("9999 .." instead of nothing) 
- 'Time since power on' ("14987" instead of "149,87 sec" in ExifView, under 'Camera Uptime')
- ...

Reproducible: Always

digiKam do not have any metadata parser code. All is delegate to Exiv2 library, including Markernote.
