Description Jo 2020-07-23 05:15:22 UTC
SUMMARY
Hi, my team uses digiKam to tag images of animals on remote wildlife cameras. We have been using it successfully with few issues for a number of years.

However, in the past month or so, we have had multiple instances of team members losing metadata tags completely, losing some but not others, and also having tags randomly changed to other tags that are incorrect (we use a supplied tag list).

I don't really know where to start as it is affecting multiple users on different platforms (Mac, Windows) and even different versions of digiKam.

I don't know if any of these errors are reproducible - they seem rather random except they are impacting multiple team members differently.

Thanks for any help!

Which windows version is used to host digiKam ?

Any virus protection is active on computer ?

Which kind of database do you use on each computer ?

What dou you seen in digiKam log using DebugView tool as explained here :

No similar problem is currently known. Do you lose tags in the metadata of the images or in digiKam's tag list? Are you using a SQLite or MySQL database? Does every user use the same database? In any case, use the current digiKam-7.0.0 with over 750 fixed bugs compared to digiKam-6.4.0.

Hi Caulier and Maik, thanks for getting back to me so quickly!

Sorry for my newb questions - 

How do we find out what database we use? I suspect we are all using something different?

I am using Windows 10 - we have other team members on Macs and possibly other versions of Windows - there are 10+ of us using digiKam to tag images and most of us work remotely (as does the world, at the moment!).

I will run the debugview tool and report back, and also get everyone to install v 7.0.0.

Thanks!

I am trying to install v7.0, but all the links still say 6.4?
Comment 5 Jo 2020-07-23 07:25:59 UTC
Hi, I am unable - it seems - to get 7.0 without Linux? I uninstalled and reinstalled 6.4.

I found details on the database - SQLite.
I will check across the team and come back if we have more issues.
Thanks

Thanks Gilles. I will download and get back to you.
Another member of our team had a strange thing happen too - when she opened her images some of them were already tagged - not all, and not all correctly, which seems vaguely similar to my initial problem. Is there some kind of auto-facial recognition that could be at play here?
Thanks,
Jo
