exif data handling for users

[Deb Nicholson]

At some point, we will need to address exif data. I think it would
be nice for the user to be able to access and search for their exif
data, but we also want to be able to let the user scrub it before
posting to their network. The best case is where the user has
access to exif data by default and the viewer does not.

Usecase 1: I want to search for all the photos from my trip to
Greece 4 years ago using my exif data.

Usecase 2: I do not want people to access the exif info for my
kid's elementary school or my company's colo.

Usecase 3: I want to see the exif info for last year's awesome
mushroom foraging spot, but absolutely do not want it made public.

Finely tuned control of exif data would represent a tangible
feature that we could offer that is not offered by flickr. I don't
have a strong opinion about how this would look on the back end. On
the front end it should be very clear what's happening and the
default should be to strip it out before posting so no one posts
exif data unless they specifically choose to.
