<p>I also like to recreate my database from time to time. I just
delete digikam's database, and let it rebuild it from the metadata
in the pictures. It might take a few hours, but I do it every
several months and it's a way to be sure that your
database<->metadata changes are synchronized. So I am not
really worried about losing the database.<br>

<div dir="ltr">Hi Marc,
<div>Thanks for your answers. </div>
<div><br>
</div>
<div>So, about version 6.4 , I choose it because is the last
official stable version. </div>
<div>I really don't like to put in risk my photos with a not
stable program.</div>
<div>(yes, I have backup and etc, but who want to recover from
backup.. very annoying right)</div>
<div><br>
</div>
<div>I hope the version 7 should be stable enough, then I
already will upgrade to it.</div>
<div><br>
</div>
<div>About the tag performance, what happened: </div>
<div>1) the moving of theses geotags took ~3 hours.</div>
<div> During this, the application don't consume more than 15%
of CPU and no disk write. </div>
<div> Apparently it worked only into the metadata database on
SQLite. </div>
<div> 2) Then I click on Album -> Write metadata to file </div>
<div> Remember that my configurations are set to lazy
synchronization.</div>
<div> Apparently they update few photos files, but I have no
sure what they did because there is no log in the application
to check.</div>
<div> They were very fast, took ~1 minute. </div>
<div> I believe they update other changes I was made before
and not that 8k tags.</div>
<div> Also because probably all photos with tag "geo:*"
already have the "geotagged" tag, so no changes need. </div>
<div> 3) now I also see the tree structure I did into the DK
don't go to the photo file, only the individual tags.</div>
<div><br>
</div>
<div>That said, for me, the application still have a logic to do
this movement of tags where don't get into consideration a
high volume of tags or was never tested with this objective. </div>

Ok, so first of all, version 6.4 is a bit old now, and lots of
bugs have <br>
been fixed in the new 7.0 release (the final version will be
released in <br>
a few days, I think).<br>
<br>
The good thing with digikam, is that it respects the previous
metadata <br>
made by other software, but also saves the new metadata into
the file or <br>
sidecar so it's permanent. That means that, moving a tag
around a tree <br>
will trigger writing that change to all pictures that share
the tags <br>
that have been affected by the move/merge. Basically digikam
has to read <br>
and then write each one of the files. So for a large library,
it can <br>
take a while. But the idea is that you have a previous idea of
the <br>
hierarchy you want to implement, and minimize the number of
"moves" you <br>
want to make in the tree. (e.g. I have several "root" tags,
the main <br>
ones being People and Places, so moving a branch of places
outside of it <br>
can affect thousands of pictures).<br>
