Re: Controlled vocabulary (John Stumbles) Digikam-users Digest, Vol 81, Issue 35

Maybe you need to look at IPTC data used by journalists to tag photos.  http://www.iptc.org/std/photometadata/documentation/GenericGuidelines/index.htm?turl=Documents%2Fiptccoreimagesection.htm

Notice that I don't believe that IPTC supports hierarchies.

They have been using IPTC for a while so they may must have worked out the bugs.  I assume they have done something similar for XMP.

Personally I use the standard-

People
Places
Events

Plus top tags like-

Animals
Plants

I also find Digikam a bit difficult to use regarding hierarchies.  To me it seems reasonable that if you select the bottom item in a hierarchy that you also want the ones above and I think it works that way but it's a bit confusing.  So if under the xmp tab if you look at the subject line you only see the final item but if you look at the tags list then you see the hierarchy.  If you use the the left pane window and click on the tags it seems to work.

Notice that I don't believe that IPTC supports hierarchies.  So the IPTC will only show the bottom item.  Hierarchies are what makes XMP so valuable.

I use Digikam 2.1.1

Re: Digikam 2.5 KDE 4.8 missing thumbnails philip5 PPA

Dear Philip, if you are going to make a KDE 4.8 PPA and it's in the near 
future, great. Otherwise I will go back to KDE 4.7. If you could let me 
know. Thank you! Manfred

I will make a special setup with packages built for KDE 4.8 this weekend at the latest if nothing happens.

Re: Controlled vocabulary

Hi Mark
I would say that David is right on the money with his comments.
I have a similar problem to yours in that i am working on a collection 
of images of plants and ordering them by the international system of 
botanical names which is a controlled vocabulary called a taxonomy ( see 
wikispecies).
The problem comes when non specialists like me want to ID a plant 
growing in my local area but i havent a clue what the botanical name of 
my plant is. So i TAG my images with descriptive words in plain english 
that have a LOOSE relationship with proper botanical descriptions that 
use a controlled vocab ( jargon ) and put the botanical descriptions 
into the xmp metadata of that image.
Cheers John Bestervaar

I haven't had that problem on any of the computers I've upgraded to 4.8. Odd that only some are having problems with thumbnails.

Re: Digikam 2.5 KDE 4.8 missing thumbnails philip5 PPA

I have now uploaded rebuilded packages of Digikam 2.5 for Ubuntu 11.10
that use the Kubuntu teams PPA with KDE 4.8.0. If you use KDE 4.8.0
from that PPA then also add my kubuntu-backports PPA. That mean that
you have to have both my "extra" PPA and the "kubuntu-backports" PPA
from my site on Launchpad, https://launchpad.net/~philip5.

You can add this PPA by typing the following command in your terminal:

sudo apt-add-repository ppa:philip5/kubuntu-backports

If you are using KDE 4.8.0 this will also give the benefit Digikam
using newer versions of exiv2 and libraw.

If you don't use KDE 4.8 with (k)ubuntu 11.10 then don't use this.

Happy digikaming!

Rotate arrows don't work - full size preview

Hi all.

I have installed digiKam 2.5.0 in Fedora 16. When I click in a
thumbnail in album view, it enlarges to the full size preview, but the
right or left rotate arrows do not cause the image to rotate.

Any thoughts... Tom.

trouble with image degradation using DK with kipi-plugin: flickr export

When I upload a photo to flickr with the kipi-plugin from Digikam, I
get bad coloration.

When I upload using the flickr web uploader I get color as I've developed.

One thing: I've developed these in photoshop running under a windows
virtual machine. But then uploaded with digikam under linux - and get
the problem. I can upload using the flickr web interface under linux
with no problem.

here's an example:

Re: trouble with image degradation using DK with kipi-plugin: flickr export

I cannot see any color difference.

If you upload a RAW file from digiKam to Flickr, it will take embeded
JPEG image from RAW instead to process RAW file, to speed-up
downloading.
