Kyle, I don't know if I'm understanding your question correctly, but I think this is something I was just reviewing. I removed "Diversity" as a subject term (we're a little loose here in applying subjects terms that aren't directly in the photo) from some photos that were of, for example, a single student studying on the lawn or in the coffee shop. The diversity in the photo was that the student was of color. When there is an image of a white student, we wouldn't put "homogeneity" or something like that, so I took off "diversity". But, as you say, users do want to be able to search for these concepts, and I think it is important not to erase differences just because it is difficult to represent that without being essentialist in metadata. Are you trying to automate this process, or are humans doing this? If automated, watch out for what Google Photos did: http://www.usatoday.com/story/tech/2015/07/01/google-apologizes-after-photos-identify-black-people-as-gorillas/29567465/ On Fri, Jan 8, 2016 at 8:06 AM, Brian Kennison <[log in to unmask]> wrote: > >I don't know what system these collections are in, but isn't this what > >tagging is for?
