Myself and several others are in the process of developing a prototype that uses Omeka for the POYi Competition. For those of you unaware, the POYi competition is a world renown journalism event that dates back to 1943. Every year the judging committee (including several Pulitzer Prize winners) accepts photograph submissions that are judged by category, composition, etc... We have some really quality content and are genuinely excited about it.
Anyway, right now the goal is to develop a new online presence for the POYi competition. The current one located at: [www.poyi.org] could stand some major work. To resolve it's problems we have decided to start over. The plan is to use Drupal to host the main POYi site and Omeka to structure, describe, and present the archived winning images. There are roughly 35,000+ of them!
I'm not sure where the project will take us at this point but hopefully Omeka will continue to fit into the equation. It's support for metadata and displays certainly is something we want to keep!
