Moving an album

John B. Egger
I created a ~200-photo album in /home/john/Pictures and added captions,
tags, and revised creation dates. Earlier, I had copied the same
photographs to /media/disk/Photographs and had created a few captions
and tags there. (There's a small digikam4.db file there dated a month
ago.) Although I worked with the photos in that location a little bit, a
month ago, but I then did much more extensive work with the
/home/john/Pictures copy. How do I get the complete set of metadata (in
/home/john/Pictures/digikam4.db) into /media/disk/Photographs?

As soon as I'm confident this is done, I'd like to completely delete the
/home/john/Pictures folder, which was always intended to be temporary.

The answer to this is probably pretty simple, but I didn't find it in
the Handbook. (Digikam 1.4.0)

So metadata you want (for some picture) is on /home/john/Pictures, and you want to discard metadata stored in /media/disk/Photographs (for the same pictures), right?

I'd setup Digikam to save metadata to pictures, sync metadata in the database with metadata in the pictures, and just copy/move pictures I need to /media/disk/Photographs, and sync the database again.

This should work. Try with a test image to become confident yourself with the process.

Not exactly, Gerlos. I want to copy the metadata from all of the 196
photos in "Pictures" to the photos in "Photographs," then completely
eliminate the /home/john/Pictures folder.

Thanks! Yes, that worked with a test image from another album.

What are the disadvantages of writing the metadata to the images? I'm
just a family snapshot guy (that's probably obvious from my questions),
not a pro like so many in this group, but there must be some advantages
to having the metadata in a separate .db file.

* copy them to any image user?
* may be long if there amre many images
* increase the risk for the image file is ever there is a write
problem (pretty often on my phone :-()

> to having the metadata in a separate .db file.

update the meta data on line without transfering all the file(s)

Good. I'm happy I helped you.

Mostly, writing metedata to images is slower, and since needs to modify your saved files (but not RAW ones), if something goes wrong you could lose, it can break your images.
If you work locally (no network collections), don't worry, it won't break anything (and anyway, you do periodic backups, don't you? ;-). In several years, I never experienced problems with metadata saved in files.

On the other side, saving metadata to files is more reliable (you always have 2 copies of metadata: in the file and in the database, and can while it can happen that the database is broken, it difficult to break hundreds on images), and when you copy or move your images metadata will be still with them.
For example, with embedded metadata, when you copy a set of shots from your desktop pc to your laptop, and open them on the laptop, you'll still be able to see any tag and description you saved before when working on your desktop.
It is nice that when you upload to Flickr your shot, they read your embedded metadata and don't need to enter your tags again! :-)
