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, -R
