DK 2.6: tags/caption from sqlite --> jpg (no go)

[Boudewijn]

Hi list,

Sorry for using such an old version of DK (and thanks for keeping improving
it): I use 2.6 on Debian Wheezy. For a while I have turned off writing metadata
to file, to speed up tagging photos.

I intended to use "Image/Write metadata to image" afterwards. Now it turns out
I can't get Digikam to write the tags from sqlite to jpg using that function.

Am I mistaken in the functionality? Is it supposed to work in 2.6? I remember
using it in a distant past, probable before v1.9. After turning on writing to
the images (via "Settings/Metadata/Behaviour" and ticking some boxes in the
"Write this information to the metadata") and writing a single tag, all tags
get rewritten from metadata to jpg.

So as a workaround I added a "touch"-tag, that I added to all images in an
album and afterwards removed, but it didn't work as expected: the new tag was
added to the file (added to the incomplete list of tags in the file), but not
the rest of the tags in sqlite. To my surprise: removing the "touch"-tag from
the image set would remove it from the images in sqlite, but not from the
images. It did write the other tags though!

Is anyone using this ancient version of DK and can confirm my findings, or even
knows a better workaround?

(Even with the workaround, my workflow is much faster when not writing to file,
so there's a benefit in the experiment ;-) )

Best regards,

Boudewijn

Probably a version issue
I presently use digikam 4.1.0 with openSuSE 13.1.
I don't know much about Debian, but I think you can find that digikam
version for your system.

Has the database scheme changed between DK2.6 and DK4.0?

The desktop that doubles as fileserver runs Debian stable, and with
dependencies as they are, it is difficult to get it to DK4 without leaving
stable.

My laptop runs Debian testing, with DK4. I copied my digikamdb from 2.6 to the
approprate location on the laptop, with the photos mounted at the appropriate
places as well.

Digikam 4 has troubles reading the 2.6 database. I hoped that
"Settings/Database migration" would help me out, but it can't read the 2.6
database either.

Any suggestion? Is an db-upgrade-script available?

Best regards,

Boudewijn

Hi
I had the same problem, I solved it this way:
First, I run DK 2.6 (sqlite) with only xmp sidecars read/write tags (no
exif, no iptc tags)
  I didnt use tool migration.
Then I installed DK 4.0 and I sync from images metadata to new database
(sqlite).
It works

Hi Maderios,

Thanks, I haven't tried the sidecars yet. I will try something in that spirit.

Did you write metadata to exif/iptc later on? That is my goal: I like to use
the jpg-versions of the photos as "sidecars" to the raw images.

I also make it more difficult than is necessary, because I don't have an upgrade
path of DK on one system. I got this ancient version running "stable" on one
system, and DK4.0 on another system.

It will be a couple of weeks before I continue solving my puzzle: I go on
holiday with only a minimal IT department :-) In case I found a way to reach
my goal, I'll post back.

Best regards,

Boudewijn

I  only use xmp sidecars read/write tags metadata
