xmp containing digikam tags for photo

SUMMARY
***
NOTE: If you are reporting a crash, please try to attach a backtrace with debug symbols.
See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports
***
The program is not reading tags from .xmp sidecar files.

STEPS TO REPRODUCE
1.  Run appimage (7.7.0 or 7.8.0) 
2.  Tools | Manitenance | Find new Files
3.  

OBSERVED RESULT
Many Images shown in No Tags collection do have tags that were written to xmp sidecars by Windows digikam 7.6.0, or later.

EXPECTED RESULT
All versions of digikamread tags written by other recent versions. 

SOFTWARE/OS VERSIONS
Windows: 
macOS: 
Linux/KDE Plasma: 
(available in About System)
KDE Plasma Version:  ?
KDE Frameworks Version: 5.96.0 
Qt Version: 5.15.5 The xcb windowing system

ADDITIONAL INFORMATION
digikam displays a warning on starting saying that the disk containing the collection cannot be found, although the collection is on an internal hard disk. After I select the option to do nothing at this stage the appimage continues to load and correctly displays my photos.

Reading in the metadata from the sidecar works without any problems. I used a JPG image to delete the metadata and gave it the same name as the sidecar. Reading from sidecars is activated in the digiKam metadata settings?

Another thing is the "XMP" extension in upper case. digiKam only checks for "xmp" in lower case, however it may work on Windows depending on the file system and settings. Click on the image and look in the right sidebar under the Properties tab to see if there is a "Yes" next to Sidecar.

Ok, now I see it's about sidecars that were created under Windows and are now read under Linux. Yes, capital letters in the "XMP" extension do not work. You have to rename the extensions, we don't plan to query both variants for performance reasons.

Thanks, I will rename the XMP files to .xmp.
