Now that you have an idea for a photo use application, you can start thinking about the specifics of describing your photos. Your task is to develop a faceted and monohierarchical metadata system (classification) that is both appropriate for your own application and maximizes reusability for the overall photo database.

1. Faceted: You have multiple, differentiated top hierarchy levels (no single root node).
2. Monohierarchical: A node will always have just one immediate parent.

Design your metadata such that all photos would be accessible from all teams’ applications, and not only for the needs of your particular application, but also for the reusability of your photos and metadata. Remember too that in describing photos they have formal properties particular to the photographic medium, the photographic device, and the context of capture.

Your assignment is to develop your metadata system and to write a short rationale explaining your metadata design choices, strengths, and weaknesses.

1. We require you to only provide us with the main facets and the first 3 subhierarchical levels in your classification. This means that if one of your facets goes into more detail than 3 hierarchical levels, we only want you to submit the first 3.
2. If some of your facets have less than 3 subhierarchical levels, you will submit as many as you have.
3. For one of the facets with more than 3 hierarchical levels, we would like you to elaborate one path down to one leaf node.
4. Every descriptor (node) in the classification from a top level facet down to the leaf node needs to have a unique name.
