Consider updating tags from EXIF when they change on source file

oPromessa commented 6 years ago

Would be nice to update ALL tags on replacePhoto and not only the mandatory checksum tag as FLICKR maintains the tags from the first load.
It would require accessing EXIF information from file...

I'm surprised flickr does not update tags based on contents of replaced file? If not, seems like this functionality is practically required if one is to update pictures in-place. To update a photo with changed tags locally and not have flickr mirror that would be sad. If there's no convenient EXIF/IPTC/XMP reading library for python, one could always parse exiftool output, which I see the documentation says the optional raw file conversion option uses already).

Confusingly I find that between digikam and darktable, my tags appear in jpeg files repeated under the following six exiftool output labels: Subject, Tags List, Last Keyword XMP, Hierarchical Subject, Catalog Sets, Keywords. Of these, it seems like the "Keywords" IPTC field is the most standard. And/or possibly the XMP "subject" field.

@timtoo

Thanks for the heads up! Will try to work on it in the coming month or so.
Tried to place the following remark on your repository timtoo/FlickrBox but it's not accepting Issues. So here hoes:

As the timtoo/FlickrBox project is in its infancy take a look at two alternatives where I'd invite you to contribute to:

flickr-uploader ... on its version 2.8.6 using flickrapi with plenty of functionality
flickr-rsync ... more towards the line of the concept of FlicrkBox of copy files over. It follows the idea of rsync (remote sync two folders)... I kicked off the migration work to flickrapi and compatibility with Python 3... but stil work in progress.
