[Shotwell] Feature request: merging databases

[Giampiero Salvi]

Hi,
Background: I use Shotwell the following way. I have a desktop
computer where I keep all my pictures and then I have a small laptop
that I bring with me when I am travelling that I use to download the
pictures from my camera and sometimes organize and publish them during
my longer trips. Both computers are running the latest version of
Ubuntu, and the version of Shotwell that comes with it.

Problem: I do not want to keep the whole database of pictures on the
small laptop because of space constraints on the disk. So, after every
trip, I would like to copy the photos to the desktop and delete them
from the laptop. I can do this easily by copying the picture files
with tools such as rsync and then importing again. The problem is that
any information contained in ~/.shotwell/data/photo.db on the laptop
is not transferred to the corresponding database on the desktop. For
example, any tags I may have added using the laptop are lost.

Question1: is there a good way to merge the SQLite databases without
breaking Shotwell functionality?

Question2 (feature request): could it be possible to add a function in
Shotwell that merges the databases and copies the picture files
between different computers?

Thank you for the great job you have done so far!!
