IMHO it could be instructive to set up Nextcloud on a NAS over a LAN, <br>
and try out how Digikam reacts to such synchronization - both databases <br>
and image files. Probably I will test this kind of a setup, but not <br>
until late October when time permits.<br>
<br>
Nextcloud/OwnCloud has fine-grained access-controls for users/groups and <br>
sharing, and has pretty advanced mechanisms for resolving conflicts in <br>
case of simultaneous edits.<br>
<br>
I presume that if using a synchronized database one would have to share <br>
_all_ the files in each local collection _and_ the paths would have to <br>
be the same on all devices, right?<br></blockquote><div><br></div><div>yes, it's the best configuration but not the best design to work on multiple computer with a common database.</div><div><br></div><div>Also remember that no lock mechanism exists yet in DK database interface.
