Title: Copying metadata (location) values to hierarchical keywords
Post by: pbb on November 20, 2022, 05:26:00 PM
I am trying to create hierarchical keywords of some of the existing image metadata, starting with the locations fields. For an example image with metadata values "My Country" and "My City" for the corresponding fields, I would like add keywords "Shooting location|My Country" and "Shooting location|My Country|My City".

But when running the command
exiftool -"HierarchicalSubject+<Shooting location|$Country" -"HierarchicalSubject+<Shooting location|$Country|$City" image.jpg


Then only the "Shooting location|My Country|My City" keyword is added.

My guess is I'm just having a minor error with placement of operating characters, or am I misunderstanding something?

You need to use -addtagsfromfile or the latter assignment overrides the first (this is Note 5 in the -tagsFromFile documentation (https://exiftool.org/exiftool_pod.html#tagsFromFile-SRCFILE-or-FMT)):

exiftool -addtagsfromfile @ -"HierarchicalSubject+<Shooting location|$Country" -"HierarchicalSubject+<Shooting location|$Country|$City" image.jpg

Splendid! It never occurred to me that I'd have to use tagsFromFile, so I never got to read that note. Thank you!

The redirection notation ("-DSTTAG<SRCTAG") uses -tagsfromfile @ implicitly.

Also see FAQ #17 (https://exiftool.org/faq.html#Q17) (chrome link (https://exiftool.org/faq.html#Q17:~:text=Note%20there%20is%20a%20complication)), paragraph starting "Note there is a complication"

Testing out Chrome's ability to directly link to test. Works in Chrome and MS Edge, probably any Chromium based browser.  Doesn't work in my old version of Firefox, but this is obviously off topic so I'll shut up now.

Then I probably won't bother.  One question, did the chrome link at least take you to FAQ #17?

FWIW your Chrome link does work for me in Safari 16 - takes me to the words 'Note there is a complication'.

It took me to the top of the FAQ page.
