I'm currently working a bit on the TYPO3.Media package (adjustments for 
Flow 2.1). In my opinion it would at least make sense to integrate the 
features you need into TYPO3.Media rather than trying to implement it 
elsewhere.

If someone™ comes up with a basic concept how reading metadata like EXIF 
can be integrated into Media, we can discuss this further here.

For the time being you can use the stream wrapper URI "resource://" . 
$resource->getHash() for access to the actual file (in order to process 
it with some EXIF library). Be aware though that in future versions of 
Flow (that is: 2.1) you can't rely on that the file is stored in your 
local file system ...

Cheers,
Robert
