I would rather suggest going Picasa way. What they do is saving
Picasa.ini file in each directory where any changes to originals were
introduced. This file has very simple markup, e.g.:

[IMG_1367.CR2]
crop=rect(0 138 3191 2264)
backuphash=11362
filters=crop=1,0,138,3191,2264;finetune=1,0.000000,0.003922,0.015686,00000000,0.067251;bw=1;radblur=1,0.422922,0.454052,0.871345,0.000000;

Thus you won't resave original file into some new fancy one and waste
disk space. You will just load original file and apply this
description of changes as adjustment layers.

That's why you guys  have such a progress with Krita. You meet often ;)
