Hi Pubuthu

Its nice to hear your interested in this project.

Since Luciano's project idea is to aggregate photos from various streams
and display them in a single gallery.
my idea is extending this idea where by enhancing the gallery to add
various meta information of photos like when this was taken, where this was
taken, tagging the photos, and adding who is in the picture, and for Gsoc
I'm expecting the student should build a gallery that can show photos
according to the meta information provided or when possible automatically
show all pics where Mr.John was present, show all pics which are taken in

1. As i understood you are referring to the  EXIF information of the photo
> is that correct ??
yes part of the data can be gathered from the  EXIF information like image
size, shooting date and time,
but others the user or the data source has to provide

2. following data tags can be retrieve form a single image itself

this depends on the data source also, for the photos taken from the phone
will have more information but
the photos which we get from our flicker account wont have all that info,
at this point the user have to provide.

3. "x,y coordination of there positions" what did u mean by that ?? (GPS

knowing that we can precisely show where Mr.John is in the portrait

Hope the above information is helpful
