Suppose I have three separate apps that do the following:

* Scan my entire Pictures folder digitising any text
* Scan my entire Pictures folder matching faces to contacts in my
address book
* Scan my entire Pictures folder adding geotags based on a separate
database of when and where I've been on holiday

Will this result in my entire photo collection being copied three times
over?  Will each of these apps have to do the whole copy from scratch
each time they run?  Will they keep a permanent separate copy?

All three of these apps are going to update the EXIF tags of the photos
as they go.  How will the results from the three apps get merged back
into the copy in the Pictures folder when they're done?
