           Summary: XMP with Google depth-map gets corrupted when metadata
                    is modified in Digikam (likely exiv2 issue)
           Product: digikam
           Version: 7.5.0
          Platform: Microsoft Windows
                OS: Microsoft Windows
            Status: REPORTED
          Severity: normal
          Priority: NOR
         Component: Metadata-Xmp
          Assignee: digikam-bugs-n...@kde.org

SUMMARY
***
An image file with XMP metadata for Google depth-map (Images taken in Portrait
mode) gets corrupted when metadata is modified in Digikam (likely exiv2 issue)
***


STEPS TO REPRODUCE
1. Open image TestPortrait_original.jpg in digikam (Refer to attached sample
files)
2. Perform an action which alters the file metadata such as adding a tag. For
example add tag - "statue"
3. Extract altered XMP using exiftool ( exiftool TestPortrait_original.jpg -b
-xmp > TestPortrait_digikam.xml)

OBSERVED RESULT
- Invalid XMP - XMP is missing the namespace - 
xmlns:Camera='http://ns.google.com/photos/dd/1.0/camera/'
- XMP metadata is not read by other applications (Example: Windows Explorer
among others)

EXPECTED RESULT
- Valid XMP, namespaces is preserved.

SOFTWARE/OS VERSIONS
Windows 11

ADDITIONAL INFORMATION
- Modifying metadata using exiftool works ok.
- Likely an issue with exiv2
