Comment 3 for bug 946544

Actually, we would like to evolve Shotwell so that all metadata edits and changes are always stored in files, not only in the database. There are several ways this can happen:

- we can write metadata changes to the original photo file (which is what happens when this checkbox is checked today)
- we can make a copy of the original file and store the metadata changes there
- we can store metadata in a sidecar file

We may someday have options that enable any of these behaviors. See http://redmine.yorba.org/issues/1798 and http://redmine.yorba.org/issues/1879 .
