Bug ID: 481762
Summary: Can't write XMP tags: to file Unknown namespace prefix
for qualified name
Classification: Applications
Product: digikam
Version: 8.2.0
Platform: Microsoft Windows
OS: Microsoft Windows
Status: REPORTED
Severity: normal
Priority: NOR
Component: Metadata-Engine
Assignee: digikam-bugs-n...@kde.org
Reporter: betoke...@gmail.com
Target Milestone: ---
SUMMARY
***
XMP tags and face regions are not being saved to file, even using exiftool.
It is not the case of XMP segment >64K:
exiftool -G1 -a -s -xmp "PXL_4487.JPG"
[XMP] XMP : (Binary data 4703 bytes,
use -b option to extract)
***
STEPS TO REPRODUCE
1. Scan/identify faces and set some tags in picture
2. Save metadata to file
OBSERVED RESULT
See comment with log extract.
EXPECTED RESULT
Face rectangles and tags should be saved to file. It seems only "XP Keywords"
and "Keywords" are, nothing else.
