            Bug ID: 341772
           Summary: Re-read metadata when image file timestamp has changed
           Product: digikam
           Version: unspecified
          Platform: Other
                OS: Linux
            Status: UNCONFIRMED
          Severity: wishlist
          Priority: NOR
         Component: Metadata
          Assignee: digikam-devel at kde.org
          Reporter: kristian.hermann.karl at gmail.com

I would like to have a feature that automatically makes digikam re-read all
image files that has a different time stamp.

If this feature already exists, I apologize that I have not yet found it, and
would gladly take any pointer in how to do this. Otherwise, I'm prepare to
write a path that implements such feature. 

This is my use case for this feature.
1) I have a Desktop with all my 88K+ images stored on SSD disks locally. All
metadata are saved to the images.
2) I have a fast home wired/wifi network, and I use sshfs to share and mount
those pics on my laptops.
3) I use a laptop to browse and occasionally update an image here and there
using a local Digikam. I add new face tags, and normal tags.
4) Now, if I start Digikam on the Desktop, these changes will not appear in
Digikam (on the Desktop machine), unless I do a complete re-read of metadata of
all 88K+ images.

My suggestion is to save the time stamps of each image file into the digikam
database. When Digikam starts, it will notice which files has changed (if they
have gotten a changed file time stamp), and initiate a re-read of those
specific image files. 

Does this sound like a feature that somebody else than me would like to have?
