[Bug 197285] New: Understand keyword hierarchies with different delimitors.

https://bugs.kde.org/show_bug.cgi?id=197285

           Summary: Understand keyword hierarchies with different
                    delimitors.
           Product: digikam
           Version: unspecified
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: wishlist
          Priority: NOR
         Component: general
        AssignedTo: [hidden email]
        ReportedBy: [hidden email]


Version:            (using KDE 4.2.4)
OS:                Linux
Installed from:    Ubuntu Packages

I have been using Lightroom for a while, and have my keywords arranged in a
hierarchy there. When I import my collection to digikam, it does not understand
that this is hierarchical.

Is it possible to make Digikam understand tag hierarchies that has other
delimiters than Digikam uses itself? Is it allowed to use Lightrooms delimiter
(is it '/'?) in a keyword name? If not, it could maybe be a small fix?

digiKam use already '/' has delimiter.

Keyword are stored with no delimiters in IPTC/XMP keywords tags. But we store
Tags path with delimiters in a dedicated digiKam XMP namespace.

I'm sure that LR do the same. We just need to know which namespace and Tags
from XMP is used.

Please provide some photos to make investigations.

One correction from my initial report. Lightroom uses "|" as delimiter.

Anders,

XMP tag used is below :

Xmp.lr.hierarchicalSubject    XmpBag      1  Places|Torpa|Fosstun

Note : Current Exiv2 library do not know LR XMP tags yet. Please open a file in
Exiv2 bugzilla.

Import and export digiKam tags from/to this LR XMP is trivial.

Anders,

Import tags from LR sound working fine with your picture now :

Look message from the console:

Please test with more image from your collection using current code from svn

Great! I'm actually in OS X at the moment, preparing for going back to Ubuntu,
so I'll check as soon as I have the chance. Do you still want the image with
more than one hierarchical tag?
