Title: Inconsistence of exported metadata to *.xmp vs. *.xml - the -rawimagedigest tag
Post by: cs on July 10, 2018, 10:28:16 AM

Hello,

in reference to: https://exiftool.org/forum/index.php?topic=2734.0 (https://exiftool.org/forum/index.php?topic=2734.0)
a md5 checksum on the sensor data is a usefull primary key for a capture.
But the quoted call of exiftool don't work. I must kill the job with ctr-c.

[worked]

Code Select

exiftool -rawimagedigest="checksum" image.jpg|raf

Code Select

exiftool -tagsfromfile image.jpg|raf image.xml
The tag -rawimagedigest is exported.
Any manipulation of the -rawimagedigest tag *.xml also worded fine.

[Don't worked]

Code Select

exiftool -tagsfromfile image.jpg|raf image.xmp
The tag -rawimagedigest isn't exported.

Code Select

exiftool -rawimagedigest="checksum" image.xmp
The tag won't be written.

Is there any sense about this behavior of exiftool out in the dark that I don't see?
https://exiftool.org/TagNames/index.html (https://exiftool.org/TagNames/index.html)
"The Writable column indicates whether the tag is writable by ExifTool. Anything but a no in this column means the tag is writable."

Environment:

RawImageDigest is an EXIF tag. It doesn't exist in XMP.

If you want it written to XMP, you need to create a user-defined tag.
