Bug ID: 446350
Summary: XMP metadata in iPhone pictures cannot be modified
Product: digikam
Version: 7.4.0
Platform: Flatpak
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Metadata-Xmp
Assignee: digikam-bugs-n...@kde.org
Reporter: iwannaber...@gmail.com
Target Milestone: ---
SUMMARY
I have been having problems with pictures taken with iPhones (several versions,
but most of my examples come from the iPhone SE and iPhone 6). Tags do not seem
to be properly written to XMP, so they lose their hierarchy, or they simply
aren't modified after writing them to the file. However, these tags appear in
IPTC.
For some reason, this is a relatively recent problem (since digikam 7.3
maybe?), since some hierarchies seem to have been been indeed written correctly
in the past.
Also, I believe that all affected pictures have a face region on them. I have
attached a sample picture (2015-06-13 18.56.11.jpg) with this problem. Noticed
how it contains the tags Hawaii, Honolulu, Waikiki that appear as first-level
tags (which should be actually hierarchical), and an additional tag called
"ASI" that is only visible in IPTC. Any attempts at modifying the tags in that
picture in digikam fail. This is why I think that it can be related to bug
#436286
As a workaround, I use exiftool to repair the XMP metadata, and after that
point it works just fine. The command I use is: exiftool -XMP:All -TagsFromFile
@ -XMP:all <file.jpg>
STEPS TO REPRODUCE
1. Select a picture taken with an iPhone and containing one face region.
2. Add some tags in a hierarchy.
3. Re-read the metadata.
OBSERVED RESULT
The hierarchy disappears. All tags appear as first-level tags, or do not appear
at all under XMP (but they do in IPTC).
EXPECTED RESULT
Tags are written properly into the file.
