Hello,

several applications, e.g. digikam save image ratings in the exif tag "Rating" but RT ignores this tag.
In the last days I took a look at the code und easily managed to read the rating tag on thumbnail creation. This works just fine for the moment.

One thing still missing is writing back the Rating tag in the case you change it in RT. I would like to do some further work on this topic but at first I'd like to discuss it with you.

One problem is that in the thumbnailbrowser RT only reads/writes file information from cache. So there is no direct access to the file exif/iptc information after the thumbnail has been created the first time.

My proposal is to allow exif/iptc editing in thumbnailbrowser. When this is available the ranking can easily be written as an exif tag, too. This also makes it possible to edit and filter iptc tags in the browser as well.

RT should not replace complete managment software like digikam which already does a great job.
My workflow is to do the tagging and sorting of my images in digikam. Afterwards i open RT and do the image adjustments.
But currently it's difficult to find a special image in RT that has been tagged and sorted in digikam. Mainly in folders with more than a few images it would be easier if you can filter this by iptc/ratings.

What do the main developer think about this?

If you agree I will try to create patch in the next weeks implementing the above behaviour.

Accessing IPTC and EXIF at thumbnail level is planned. You can already see a "Tagging" tab in the thumbnail browser. This will hopefully make it easier to save/load rating to/from exif data as well.
