Matti,

DNG has JPEG preview editable.

All preview in raw file are stored in a dedicated makenotes. In theory, if you
can change makernote tags, you can edit preview image (has in PEF format for
ex.)

Currently, digiKam use Exiv2 library which provide a limited list of editable
RAW metadata.

Exiftool has a bigger list. So i let's you imagine...

In proprietary world, each maker provide software in this way. I'm sure that
Canon do it...

But the best format for that is DNG, because it's standardized and based on
TIFF/EP.
