Digital Asset Management
Upload assets in bulk, assign them multiple metadata and then have them displayed quickly/easily through out the site using repeaters which specifically target the list of metadata.
Upload a photo of a tree.
Meta data on characteristics of image: Tree, Apple, In Bloom, Backyard, Sunset Tree
Meta data on photograph: rights managed, photographer, date, price, limitations.
Meta data on access/sites/access: Allowed on intranet, not allowed on external.
Just standard DAM functionality. Seems like a popular module. It would make managing images in the Media Library a whole lot easier to manage too.
