That's a pretty broad > network of facts. The work we did some years ago on photo annotation following the foaf workshop is probably still a good approach: http://esw.w3.org/topic/SimplePhotoAnnotation The lat/long should be attached to the photo with dcterms:spatial. > 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. We simply used dc:date for the date the photo was taken, but that might run afoul of using things like dcterms:created and dcterms:issued (because of sub-property relationships) if you're trying to encode those things. .greg
