Photo Extensions to RSS from Pheed.Com: Syndicated Photography Feeds. [Scripting News]

Here's a site that Dave Winer found that is experimenting with using extensions to RSS 2.0 to better describe the attributes of photos, called "pheeds", and to aggregate pheeds from different sites/photographers. I'm no RSS jockey but it looks like they have taken some of the useful elements used to categorize images and added them to RSS. I wonder how this lines up to either metadata standards being adopted by the camera vendors or tagging and categorization schemes used by stock agencies or photo-desk/news wire applications? It would be nice if they made it so libraries of images that were already catalogued could be easily and automatically represented as pheeds. It looks like the person behind Pheed.com is a talented commercial photographer, Mark Meyer, so I'd assume that he's familiar with those formats.
This kind of use of RSS could be used to create a dynamic master catalog of photos from different sources. Is this a threat to stock agencies or maybe an opportunity.................
