apply keywords/tags from one album to contents of another?

[Daniel Bauer-2]

Hi again

Might be another stupid question and I'm sorry if I bother you again for
something you've already solved and I just haven't found it...

Let's say I have album "big" with images with keywords/tags. Now I use "extras
-> batch jobs -> resize images" to resize them into album "small". There the
photos don't have the tags, of course.

What can I do to make the photos of the same name (but in different
directories/albums) having the same tags? This is not of big importance, but
it would be nice to have it.

The only way that came into my head first was to write directly into the
Sqlite-database. But this appears quite tricky to me, because I'd have to
find out the id's in the Images table of the "big" and the "small", then look
up the tagid in ImageTags for "big" and build an INSERT command for "small".  
(And I don't know much about scripting on Linux yet, my programming knowledge
is nearly NULL, I wasn't even able to import the Sqlite dump into a
MySQL-database for testing a bit...)

Then I thought, ok, I'll copy all from "big" to "small" (tags will be copied
as well), then do the resize job with "overwrite" option. This works, but I'm
asked for each photo if I really want to overwrite it. That's ok, but when
resizing 800 photos it's a bit a lot of clicking ;-)

Finally I used kind of a brute method: copy all from "big" to "small", resize
with rename-option in the same directory, closing digikam, deleting all the
originals in "small", renaming all the new pictures back to the original
names and reopen digikam. Not very elegant, but it works...

Of course I'd pefer a more elegant way and I almost fear, that once again
there already is one and I was just to blind to descover it. So if anybody
has a hint for me, I'd be greatful...

Have a nice weekend!

Daniel

There is no direct way, but you can use the advanced search to select all
images from both folders, so you can tag them quickly.

Please report a wish on bugs.kde.org: 'Make a overwrite all button here and
here'.

No, the resize is a kipi action, so keeping the tags can be a pain in the ..
to implement. The overwrite all might be the best way out here.

I think there is a general problem related to this one. that
is relation between digikam and other system actions.

for example, I use a script to rename the files (simple mmv
"*" XXXX#1). The files are the same, but digikam don't know.

so if I forget to do so before tagging or simply creating
the album icon, the data is lost.

there should be two ways (at user will) to identify the
files in digikam.

* first by name (a file could be modified, but keep its
digikam stuff is the name is kept the same) - this need some
sort of file name storage,

* second by file content. It should be possible to keep a
file consistent through changing name. some sort of ID (raw
file node number, md5sum of some part of the file...)

I know this is not easy and I don't ask such thing for
tomorrow (but for yesterday it would be fine :-)))

thanks

I believe similar reports exist already in bugs.kde.org. Please check and add
a comment if needed. md5 could be a nice solution here.
