Fwd: Re: tags/keywords between Adobe Lightroom and Digikam

Forwarding to list for Jim's benefit.

Look in code :

https://projects.kde.org/projects/extragear/graphics/digikam/repository/revisions/master/entry/utilities/setup/setupmetadata.cpp#L206

This option is enabled only if Exiv2 shared lib is compiled with XMP
support. It's optional at compilation time.

Many thanks folks - I enjoy the discussion about workflow and other
softwares - would love to finally dump my windows XP.

I will study the links provided by Gilles and see if I can make head
or tails from them to enable xmp in DK.

Martin - when you say you export to jpeg then tag (both raw and jpeg)
does this mean you have to tag two different files (images)? I would
want to tag an image only once - preferably the raw, and then have any
photo derived from it to carry the original tags from the raw. You can
see I'm not understanding how you do this.

thanks, Jim

Gilles was basically saying that the library that deals with metadata,
Exiv2, has not been compiled with support for XMP. Exiv2 is not a part
of digikam but is needed by digikam to work. So the next question is
'where did you get your version of digikam and supporting files and how
did you install it on your machine?'

Yes, I always tag two files (at least). But this is not that much work as it
sounds. I simply have to select two (or even more files) and the rest of the
work is the same as you only would tag one file.

The point is: automatic tagging jpeg from raw is fine but not all my jpeg
files have the same tags as the corresponding raw files (some by accident I
must confess). If I select files for printing I use tagging (print-date tag)
for this. But I don't want my raw files to be printed. And if I decide to
rework the settings (does not happen that often) I want to copy the tags from
the old jpeg instead the one from the raw files.

The history function is not of much use for me. As long as the history only
handles final pictures and not the process which leads to the new picture its
usage is limited (for me). So even if the old tag belongs to a new photo
(different parameter set) I can find out which photos I had printed. And with
my backup I can restore the photo.

ok - I've found my problem (one at least). Thanks Andrew for the
interpretation. I use Gentoo and had not enable the xmp use flag for
compiling exiv2. Will enable that and recompile programs that can use
it.

Martin: ok - I understand that. In DK I separate out my files by file
directories, so I have a date parent directory with the untouched
raws, then a jpeg subdirectory for images sized for web. And I have a
"working" subdirectory for tiffs or photoshop psd's. So with the way I
am set up I couldn't really select all the images unless I filter
somehow. Lightroom shows all images in subdirectories if you choose,
so it would be very easy to do as you do. Maybe DK has that capability
too to show all images in subdirectories.. but I find it confusing so
see all versions of an image at once.

I used different subfolders for different types of photos once but
finally decided to store them all in one folder. With this I can see if
I already have one gimp file at once without the need to check another
subfolder. Usually I run gimp from within digikam but not always. And
all in one folder makes backup management much easier.

You might want to use the functionalities provided by Digikam. As for myself, I have all the versions of the same picture in the same album/folder. When you want to filter certain files only, you only have to use the filtering criteria: only raw, only jpeg, only tiff, everything but raw, etc. And if you want to make a more complicated selection (using date or whatever), you can use the search menu, and all the filtering capabilities of tags, color labels and such.
In addition, DK now provides a grouping functionality that allows to put all the versions of a picture in the same group; you can then either display one of each group, or all the versions ... unfortunately, there seems to be a bug that sometimes prevents DK to display a group (at the moment, I have 2 - in 30000 - I cannot see in DK); but hopefully, this issue will be solved quite soon.

I agree with that. As Digikam provides plenty of tools to filter/select images with a great number of criteria, it's better to rely on its powerfulness to find 'the' image you're looking for at 't' time.
I use albums/folders to roughly divide my whole collection, so I more or less know where I can find something, in order to reduce the searching scope for Digikam. For events, or trips, or whatever where I take 50 to 500 pictures, or many more, I create a specific folder; the rest goes in a monthly 'day-to-day' folder. And the whole in organized by years.
I am about to complete my 10th year in numeric photography, and it has worked for me all this time (I used Photoshop Elements with Windows before switching to Linux/Digikam and have been able to keep the whole structure and the tags from the beginning).

Recompiled exiv2 with xmp support (added it to my make.conf file and
did an "emerge -avuND @world" to make sure anything else using xmp
would be recompiled but I think only exiv2 and tellico were done.

Still grayed out in DK settings.
If I look at that same Metadata settings and look at the viewers, they
are all blank - no options selected- and I'm not sure how that ought
to be. There's too many things in there for me to grasp, but if I
enable them it doesn't appear to help in the Behavior tab with the
Read xmp sidecars.

I did do a restart of the computer just in case and for other reasons as well.

cheers, Jim

KDE libkexiv2 interface for digiKam need to be recompiled after Exiv2 changes.

Also, look into Help/Components Info dialog for details about Exiv2
and metadata capabilities if all is fine.

yes, that was that issue. Thanks.. now I will see if I can get it to
read LightRoom's xmp files.. doesn't want to right off but I'll
explore this a bit.
