Tags are written and visible to windows explorer but

[I3ordo]

 Hi!
I would love to write a wall-o-text but have a feeling that i should it simple and to the point.

the tags we add through exiff tool are only readable to windows explorer, and they are invisibly broken to the user unless the tags are edited by window's explorer.

i zipped the problematically tagged image (incase slack processes and fixes it) https://slack-files.com/TSS4RSSUA-F039CM56WUF-9a7cd9c319

I was wondering if one can point me and my friend in the right direction;

WALL-0-TXT ;

Me and a friend (that does the phyton scripting) are trying to write tags to image files, thus eliminate the need the branching folder structures.

Currently we have come so far and are able to write to and search by: "Title", "Authors", "Copyright",  "Camera Maker" and "Camera model";
but the "tags" section is not yielding any results.

The tags written by exiff tool look totally correct when right click\ details; but cant be read by picasa or lightroom. They become readable (searcable by other programs) only when  tags are modified by the user through windows r.click \"image details".

After the images are processed, the "supposedly broken" tags look like this:


Yet, I can find the file with the search string "tag: aethetics" by windows explorer's search box.
but same thing wont happen as somehow the tags are not compatible /visible to programs like picasa 3.2 or acdsee photo studio or adobe lightroom classic.

When i find the image in light room (for example) , i see  the keywords as an empty field.  I can add to the empty list and and search for the newly added that but the existing ones are still invisible to the programs other than the windows explorer.

While trouble shooting, i noticed that i can make the keywords work (yielding as results) by browsing to the file with explorer and edit one of the tags. or even ctrl+a cut and repaste the whole the tags to make them become useable universally.


The non-readable tags are copy/pasted like this       

Code Select Expand

aesthetics; vision; fabiano; armchair;

And the "now"readable ones looks exactly the same

Code Select Expand

aesthetics; vision; fabiano; armchair; test; (i added  the word "test" just to make all tags working again.)

So the tags we add through exiff tool are only readable to windows explorer(as far as i know) and they are invisibly broken to the user unless the tags are re-written by window's explorer.

I will ask and write here the exact line that is used for the exiff tool but wanted first to know if this was an already known issue (which i have not come across the reference pages.)


Thank you for your supportive suggestions.

This is a FAQ #3.

Looking at your file, the reason is that you're writing the keywords to XPKeywords.  This is a tag that almost nothing outside of Windows will read.

The reason it becomes visible after you edit it through the Properties window is because Windows is then rewriting the data to the more standard XMP:Subject, possibly IPTC:Keywords.  If you run the command in FAQ #3 before and after, you will see the changes and the new locations.

You can find a table in this post which lists what tags Windows will read for each of it's properties.  And this post does the same for e Lightroom.  It should still be mostly correct even though it's based upon an older version of LR.

Thank you very much for the clarification, i will pass through the information to my friend and hopefully the tool will be feature enough for  serious  usage.
