Description swami.kevala 2011-11-09 09:03:23 UTC
Version:           1.9.0
OS:                Linux

After tagging my images with a two-level tag (e.g. Family/John), I run the  Tools -> 'write metadata to all images' function. (Under the Configure/Metadata/Common Metadata Actions settings I have checked "Save image tags as "Keywords" tags in metadata embedded in files")

Now when I go to Image -> Metadata -> Edit IPTC, I notice that it has stored two separate keywords, "Family" and "John", side by side. This is not what I want. I want it to store a single keyword "Family.John" or "Family/John".

And when I read the metadata back from the images, I want the tag hierarchy to be recreated.

Reproducible: Always

Steps to Reproduce:
As above

Actual Results:  
As above

Expected Results:  
As above

Tag hierarchies are preserved in XMP metadata, through digiKam namespace.

IPTC is limited as tags size and Characters encoding. XMP is not limited.

digiKam use XMP in first to recreate tag hierarchies from images to DB.

Also, use 2.x serie instead unmaintained 1.x. 2.3.0 is just released...

I have just changed to Ubuntu 11.10 (which includes digikam v2.1.1). The
tag hierarchy still doesn't appear to be getting preserved in the XMP
metadata. Was this fixed in a later version?

It support XMP since 1.x release.

Do you turn metadata writting in images through digiKam configuration dialog ?
