Dear Digikam users,

I have a problem and I'm hoping someone here can help.

I have about 9000 images in an IMatch database, running on windows in
a VirtualBox. I've been putting off transferring my categorization
efforts over to Digikam, but IMatch isn't running as well as it used
to in the VirtualBox - an understatement.

If it is relevant, I'm running Digikam 10.4 on Ubuntu Lucid using
icewm as the window manager, with a mix of gnome, kde, and other apps.

I have hierarchical categories/tags in IMatch. IMatch can write IPTC
and XMP to the image file itself or to a side-car. About half of my
images are jpegs. The rest are raw (CR2) files. IMatch can write to
both raw and jpeg, but writing to the raw files is very, very, very
slow.

I made a test run with some jpegs, using an IMatch script to write the
keywords to the IPTC keywords field. Digikam  doesn't import the
dotted keywords from the IPTC keywords field as tags - the dotted
keywords just get ignored, though they are visible in the Digikam IPTC
window.

 I am going to ask the IMatch forum for advice on how to get the tag
hierarchy from the IMatch database into the images, but I'm not quite
sure where the keywords need to go for Digikam to be able to import
them as tags. There is a script that rights to the lightroom subject
field, but that probably won't help. The scripts available to me in
IMatch use dotted notation to indicate a hierarchy, though perhaps a
kind soul on the IMatch forum could help me modify a script to output
forward-slash notation, if necessary.

I think the tags ought to go in xmp subject field? digikam tag field?
someplace else? slash? dot? Is there a way to get Digikam to read
dotted keywords from IPTC keywords?

I know this is a very dry subject for someone not in my predicament.
But trying to get this project done has actually reduced me to tears.
Any advice, help, inspiration is much appreciated. I have some
familiarity with exiftool at the command line, if that will help.

Many, many thanks in advance,
Elle Stone

This is a very important subject from me, to be able to import tags
hierarchies from another photo-management software.

I already solved lightroom, picasa, and iphoto import through XMP
metadata. imach is not yet done.

This is not help. Go to Help/Components Info and give me a copy of all
info provided, in cluding right digiKam version show in the dialog.

The id provided by ubuntu do not fell digiKam release id. Do not ask me why...

In all case, i recommend to update to last digiKam 1.3.0 release.
Also, to have Exiv2 library updated to last 0.20.0 is very there
important here.

yes, i know. I already tested imach on my computer.

Note that xmp side car is not yet fully supported by digiKam. This is
will done with digiKam 2.0.0. It's under development.

digiKam do not use a '.' as separator, but '/'.

Look this code relevant :

http://lxr.kde.org/source/extragear/graphics/digikam/libs/dmetadata/dmetadata.cpp#574

Look like, for LightRoom, i have adapted code to use '|' instead '/'.
I can do it also for Imach.

You will see also there where tags path list list will be parsed from
metadata. By order :

Xmp.digiKam.TagsList        => 1/ from digiKam xpm namespace. this is
out of subject there for you.
Xmp.lr.hierarchicalSubject   => 2/ from LightRoom namespace.
Xmp.dc.subject                  => 3./ from standard xmp keywords.
Iptc.Application2.Keywords  => 4/ and finaly, from standard iptc keywords

Now, i need to know WHERE Imach write tags path list in metadata. I
need a sample image processed to check. A jpeg file is enough here.
lease send me it by private mail.

and this to be continued (:=)))

Re: (no subject)

Elle Stone
Gilles,

Thank you so much for helping. It may take a couple of days before
I've understood and collected all the info you requested. For now,
here's the digiKam components:

digiKam version 1.3.0
Exiv2 can write to Jp2: Yes
Exiv2 can write to Jpeg: Yes
Exiv2 can write to Pgf: No
Exiv2 can write to Png: Yes
Exiv2 can write to Tiff: Yes
Exiv2 supports XMP metadata: Yes
LibCImg: 130
LibExiv2: 0.19
LibJPEG: 62
LibJasper: 1.900.1
LibKDE: 4.4.5 (KDE 4.4.5)
LibKExiv2: 1.1.0
LibKdcraw: 1.1.0
LibLCMS: 118
LibPGF: 6.09.44
LibPNG: 1.2.42
LibQt: 4.6.3
LibRaw: 0.10.0-Beta1
LibTIFF: LIBTIFF, Version 3.9.2 Copyright (c) 1988-1996 Sam Leffler
Copyright (c) 1991-1996 Silicon Graphics, Inc.
Marble widget: 0.9.3
Parallelized demosaicing: Yes
Database backend: QSQLITE
LibGphoto2: 2.4.8
LibKipi: 1.0.0

I'm sending a sample jpeg to your private email. And I will strive to
update exiv2 to 0.20.

I looked at the code in
http://lxr.kde.org/source/extragear/graphics/digikam/libs/dmetadata/dmetadata.cpp#574.
The easiest IMatch script for me to use is the one that writes dotted
keywords to IPTC keyword field, as writing directly to XMP for a bunch
of files at once is not well-supported in IMatch v 3.6. All the other
available scripts would require modification, if they would run at
all.

Thank you again for helping,

Elle

ok. We can try with Exiv2 0.19 for the moment.

try to send me the JPEG file with XMP metadata patched by Imach, i
will fix digiKam metadata parser to import Imach tags path list to
digiKam DB

Note : I will work with current implementation from KDE svn trunk,
which is next 1.4.0 release.

I recommend to recompile digiKam using the code and install it in production.

There is no risk to use it as well in production. there is only small
change in 1.4.0 against 1.3.0, which are only bugfix. The main changes
are located in a dedicated branche which will be future 2.0.0 release.

The goal to use current implementation from svn is to be able to test
my fix directly on your computer.

Look at this page to know how to checkout code from svn :

Gilles, I sent you a jpeg with tags saved to IPTC keywords field as
dotted-notation. Do you mean try to write the tags to XMP rather than
to IPTC? I don't know if I can actually do that - there is an IMatch
script that uses exiftool to write to XMP, but I haven't gotten the
script to work and there is a good chance it won't work as most of the
scripts no longer work on my virtual machine.

I will try svn whenever you would like.

I'm not sure to understand. You want mean that Imach do not manage
image metadata by default ? You need to use an extension script to do
it ?

About IPTC against IPTC : yes XMP will be better than IPTC. IPTC are
ascii limited and string are size limited. XMP support UTF8 and don't
have size limitation.

digiKam 1.4 compiled from svn without problems, other than a few
missing programs which were easy to install.

I took the precaution of un-installing 1.3 and removing the database
before installing 1.4. First run with just the one jpeg went
perfectly. I ran it from a terminal to see the output - didn't see any
major issues or complaints.

Many, many thanks. I will fire up the virtual machine and try to get
tags written to the rest of the jpegs. I will write again with a
progress report after I turn digiKam loose on the whole collection of
jpegs.

All the images in my IMatch database have been successfully
transferred over to digiKam. Thanks to Gilles, all my keywords are in
place, at least for the jpegs. I think I will just have to re-tag the
3500 raw files.

While still in IMatch I used the IMatch IPTC-writer to write country,
state, city, (sub)location. I'm not sure if digiKam read the location,
though country, state, city is in each jpeg. Then I used an
IMatch-supplied script to batch-copy categories to dotted.hierarchy
IPTC keywords.

Before adding the "collection" to digiKam, I used exiftool to: (1)
remove all xmp tags from each image, along with quite a few individual
iptc tags that had erroneous information. At some time in the past,
somehow a tagging scheme that I had since ceased using had gotten
embedded in a lot of the images, and that tagging scheme was being
read by digiKam instead of the tags in IPTC. (2) add copyright,
by-line, by-line title, contact information to IPTC. (3) rename from
yyyymmdd_hhmmss.ext to yymmdd-##.ext and rearrange file tree from
yyyy/mm/dd to yy/mm - makes using the command line a lot easier when
the path and file name are short.

The above steps took quite a bit of experimentation with exiftool to
get right, plus the time to actually write to all the images, plus
further experimentation with digiKam on test directories. It was with
a bit of trepidation that I turned digiKam loose on the newly
restructured file tree to import roughly 9000 images. But the import
was smooth and quick.

Thank you Gilles and thank you digiKam.

Later, with XMP side car support currently under implementation for
digiKam 2.0, you will be able to backport RAW tags in digiKam.

Reverse geocoding in under developement for digiKam 2.0.

I lets Michael or Gabriel explain better there.

Take a look here also:

De nada. Quick and simple to do.
