Hm, not sure. We can ask in this list: How does your camera do it? I'll need 
to check with mine.

I'd assume that for files a (RAW) and b (JPEG) to form a pair,
- the same basename, only different suffixes, when downloading from the 
camera, is sufficient
- the exact same creation date is necessary, but not sufficient if there are 
other pictures with the same date+time
- same value in one of some metadata fields implemented as a UUID or click 
counter is sufficient (see DMetadata::getImageUuid for potential candidates, 
but the intention there is different)
