[Bug 286165] New: Tag hierarchy not preserved when exporting metadata to IPTC

https://bugs.kde.org/show_bug.cgi?id=286165

           Summary: Tag hierarchy not preserved when exporting metadata to
                    IPTC
           Product: digikam
           Version: 1.9.0
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: Tags
        AssignedTo: [hidden email]
        ReportedBy: [hidden email]


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 ?
