One of my projects is a huge alumni archive. As I get albums scanned and organized, I'm uploading versions to Facebook.
I would like a way to pull down that information. E.g.
Pull the names of people tagged into the IPCT extension field "Person Shown in the Image" along with the coordinates. (Facebook uses percentage of height and width as location info. This is invariant under scaling, but obviously fails with cropping.)
I'd like to slurp up the comments too, repurposing a field that allows long text strings.
The facebook API makes the FB end of this look simple.
