lost a lot of information about photo rating!!!

[samR]

Hello

I wanted to save the informations about my photos in digikam, especially the
rating I give to my favorite photos (1 to 5 stars), because I had bad
experience before (lost partly theses ratings)
I went to Tool --> migrate database (sorry if its approximate translation - I
use digikam in french). Th computer did many things for some time. Then I had
to rebuild all the thumbnails.. then I lopst completely the rating I give to
every single photo in each of my albums..... !!!!! This is absolutely not what
I wanted to do!!! I can I retrieve everything?
And is giving a rating to my favorite photos the good way to manage and sort
them? or is there another way to do?
other related question:
How can I save properly this kind of information? (information about which
photos are my favorite photos, the rating I give to each)
And can this information be shared with other program, like gwenview?

Thanks for your help.

Samuel

If we are not talking about raw pictures and you did previously write
metadata to pictures there is a chance that it comes back by read
metadata from photo, in my opinion it schould count at least for tags,
maybe is a rating some sort of a tag too.

using tags gives the opportunity to far more complex management

It can maybe be done by writing metadata to photo in digikam. Maybe
gwenview can read (some of) it, but it will certainly not read from
digikams db, if you going to test it, please share your experience. And
using sidecarfiles is a no go as you can read in yesterdays messages.

yes, but as Gwenview author has never wanted to use libkexiv2
interface (it use a dedicated metadata interface based on Exiv2), it
will lost digiKam experience !

no it cannot. Also digiKam DB interface is not shared (and it will be
never shared) and it complex. At least schema is shared, but we can
change it between digiKam version.

The last point is Nepomuk, but it require a nepomuk DB server in
background. And not all information are shared like this.

So npw that Samuel brought this up; what is the best way to safelu keep that metadata information if one is working with RAW files?
1. Create a jpeg loaded with all the tags, ranking, etc. from the RAW in lue of the sidecard?
2. Try to write the metadata to the RAW? (Not recommended)
3. Use sidecards?
4. Use digiKamvs database?

I know personal preference plays a role. My question is more about reliability and how the program is intended to be used at this point.

Thnks.

I use option 4, with always some fresh copies around. Not that I ever needed them, just to be sure. A lot of things can happen not neccecarilly related to digikam.
Not reading from or storing to pictures speeds op your work.

In a related way, my single complaint with Digikam is that I've lost
tags several times in the past couple of years, namely every time i've
upgraded or changed disks.  Digikam recognizes that the UUID has changed
and all my tags are gone.  The images (RAW & jpg) and folders and such
are all there, which is the  most important thing--but any user data is
gone.   I won't use tags any more until I have a better understanding of
how to transfer tags across disk changes/replacements/upgrades.  I'd
rather it never looked at UUID, which I think of as a machine pointer,
as opposed to a handle with deliberate semantics (path or mountpoint).

Thanks,

I think the problem is not so much that you changed disks, as Digikam doesn't know where the database file is. I always change the database location to the same directory as my pictures (settings --> configure digikam --> database settings) This way if I move my pictures folder to a new drive, or even a different computer, all my tags and settings remain.

Hope this helps.
