I'm wondering if anyone knows of an ideal metadata scheme for digital oral history projects and collections. I've seen many different approaches, most often DublinCore-based, but none seem to follow any identifiable standard specific to the oral history medium or field as a whole. In addition to the use of DublinCore et al, have there been any attempts to create or use something like PBCore (NPR/PBS multimedia metadata scheme http://pbcore.org/2.0/) that answers specifically to some of the unique characteristics of oral history media? Are there any agreed upon standards, exemplary use cases, important articles, etc.?
EDIT: I've created a public open Zotero Group that explores this issue as well. Join/Add if interested: https://www.zotero.org/groups/digital_oral_history_and_metadata
