SUMMARY

I have been using Windows Photo Gallery, purely because of tagging. I have a tagged image where the tag = Animals/Dogs/Fido.

Although DigiKam shows the correct full path in the Tag manager, if I add that same tag to another image then just the last part gets added to that image i.e. "Fido".


STEPS TO REPRODUCE
1. Open a photo that has a tag with full path i.e Animals/Dogs/Fido
2. Copy that tag to a un-tagged image
3. 

OBSERVED RESULT
New image tag = Fido


EXPECTED RESULT
New image tag should = Animals/Dogs/Fido

The tag path is of course saved in by digiKam. It depends on which metadata you want to use in the image. The full tag path is saved in:

XMP-acdsee-categories
XMP-lr-HierarchicalSubject
XMP-digiKam-TagsList
XMP-MicrosoftPhoto-LastKeywordXMP
XMP-medipro-CatalogSets

There are some metadata in which only the last keyword is saved by standard.
You have to report in more detail how you come to the conclusion that digiKam is doing something wrong.

One more note about the tags in the thumbnail, only the last keyword is shown here for reasons of space. In the right sidebar in the Properties tab or if you activate the tooltips in the setup above the thumbnail, you can see the full path.

This image show the properties of the photo after it has been tagged by digicam
As you can see just the last part is written

I have taken some screenshots of what is happening.

As you can see only the last part of the tag is written to the actual photo "Fido"

Well, Windows stores a tags path in Xmp.dc.subject. One can argue about it, because the standard does not really provide for it. However, you can set up digiKam in the advanced metadata settings so that it is compatible with Windows. See the screenshot.

1. Deactivate the default entry
2. Create a new Xmp.dc.subject entry as in the screenshot.
