5.7.0: I screwed up

[AndriusWild]

I think you will have to re-write xmp sidecars for all raw images.
If you also use daktable and set it to write to xmp sidecars too make sure
to backup all the sidecars first.
I usually have no problem with darktable and digikam writing in the same xmp
sidecar but who knows what can happen.
You don't want to lose all darktable editing history in addition to the lost
tagging info.

For future you might want to rename files on import only and do not change
their names after that.
I find the following naming structure useful:
yyyymmdd_hhmmss_(unique number).jpg/dng
where unique number can be either a random number or the original number out
of camera e.g. if the image was IMG0023.dng on the SD card you can extract
the 0023 to make the name  yyyymmdd_hhmmss_0023.dng
I use Rapid Photo Downloader for that.

Any random sequence of numbers will work too. I use
$(FILE_FOLDER)/$(FILE_NAME)_$(SEQUENCE) when exporting jpeg from darktable.

Pros of such naming structure:
No spaces
Readable date and time
No duplicates
