Steve Behrens’ 2003 article, “Too disorganized for digital era? DAM it!” brought up metadata in a context outside of libraries that I had not really considered before. However, it makes sense that television and radio stations have archives and have access to other news archives to create news segments – Behrens’ prime example being the use of previous news stories on Osama Bin Laden to create news content post-9/11 – and therefore these stations require an organization system and archivists to organize and access news stories.
In this specific example, WGBH, a Boston television station, opened a lab to work with a digital asset management system (DAM) to, well, organize its digital assets. To do this, a schema was developed based on Dublin Core and a created shared audio-visual (AV) dictionary that is called PB Core (Public Broadcasting Metadata Dictionary). PB Core uses 58 elements, many of which are based on Dublin Core elements but it makes a point to expand on elements specific to AV assets. The intention is for other stations to be able to easily adopt this schema so that stations can easily create and also share metadata. Going back to the Bin Laden example, with this DAM system in place, station archivists could save themselves hours trying to locate stories once they’ve been appropriately marked up and they would also find more sources by not having to guess or watch a week’s worth of old footage to find background information.
PB Core, which is now part of the American Archive Initiative, has since become “PBCore 2.0” and has added element attributes to further specify sources and taxonomies which should make it a preferred format for semantic web applications involving news stories in the future.
