We are looking for ideas to help users search our collections for photos based on concepts (e.g. diversity) rather than the subject matter depicted in the photo. Since the high priority institutional objectives are often behind requests for these items, we'd really like a better solution than telling them to go fishing. Concepts that are not part of the subject matter are subjective and contextual by nature, but we can identify photos that satisfy some of the more common requests. However, we have not come up with a way to add appropriate access points -- methods that come to mind would/should get anyone involved tarred, feathered, and run out of town on a rail. Parenthetical qualifiers work reasonably well for some concepts and visual elements not directly related to the actual subject matter in a photo. But this method doesn't work for sensitive topics. Has anyone come up with a good way to provide this sort of access? Thanks, kyle
