Multiple LR hierarchies.

Description Anders Rønningen 2009-06-20 17:19:13 UTC 
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?
Comment 1 caulier.gilles 2009-06-20 17:30:00 UTC 
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.

Comment 3 Anders Rønningen 2009-06-20 23:36:04 UTC 
One correction from my initial report. Lightroom uses "|" as delimiter.
Comment 4 caulier.gilles 2009-06-23 15:19:04 UTC 
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,

Can you provide an image with more than one keywords hierarchy assigned, please ?

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 (1.0.0-beta2)

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?
Comment 10 caulier.gilles 2009-06-23 18:51:07 UTC 
yes, i want to check multiple keywords path from LR...
