The tags are still in the database, the path or device identifier may have 
changed after replugging the proper disk. But I don't know how to correct that 
(for one, it depends on the operating system used)

XMP sidecars would have helped, in that you can then reread the metadata from 
the sidecars. But then you will end up with superfluous information in your 
database (not dangerous, just taking up space)

That's a completely different problem: there are several places tags etc. can 
be stored (even within the XMP metadata), if Piwigo uses a location that 
digikam can't understand (or vice versa), you'll have to use some tricks.
