Re: how to mark up a photo on the web

Ben,

This is not in the context of RDFa, but you might be interested in  
some (unfinished) work I did 3 or 4 years ago on this topic:

http://www.holygoat.co.uk/projects/images/

Mark's point about attaching the longitude and latitude to the URL is  
quite important: a particular JPEG at some URL is an instantiation of  
some image, the taking of which is an event that occurred at some  
place and time (or perhaps a composition of several images, or a  
thumbnail of an image, or...). That's a pretty broad network of facts.

Similarly, the time a photograph was taken, the time a particular  
version of it was produced, and the time that a particular JPEG file  
was created on a server can all be different -- the first is probably  
what users will want to search on, but the last is what the filesystem  
will give you.

Keeping these indirections in place prevents nonsensical output, such  
as a JPEG having a current location, and allows for useful scenarios  
such as the indirect associations between various sizes of the same  
image.

HTH,
