Exiftool is giving this warning when I am setting artist tag for png images.
exiftool -artist=hi 1159.png
Warning: [minor] Ignored empty rdf:Seq list for dc:subject - 1159.png
1 image files updated
It is updating the artist tag to hi but giving this warning. I don't want to see these warnings. What should I do?
Note: this warning is not comming for .jpg images. I don't understand why it is happening.
You can safely ignore this error. No data is lost. Some software used on this image wrote an empty Subject tag. To ignore all minor errors, you can add -m to your command.
If you want to "fix" this file to avoid the error in the future, you can use this command to rewrite the XMP tags:
exiftool -xmp:all= -tagsfromfile @ -xmp:all <FILE>
To find any file with this or a similar error, you can use this command:
exiftool -if '$warning=~/Ignored empty rdf:Seq/' -warning
