[ansel] Request for API pointers

[Heath S. Hendrickson]

I'm starting to work on the TODO of reading the EXIF data in on image 
upload and though it would be best to use the Horde multi-variable 
storage mechanism for storing the data in the DB... can anyone point me 
to any documentation (or even where this is set up/created/read) so I 
can figure out how to put the data into the proper format?

I'm referring to

a:2:{s:4:"time";i:1079941418;s:4:"host";s:16:"ultraspace.local";}

as stored in the horde_prefs table...

Thanks,
heath
