Metadata

We created a metadata record for each commercial in the AdViews collection consisting of the following tags/elements. Each of these elements is mapped to a Dublin Core metadata element (more details coming soon).

  • Filename (dmbbreel#segment#)    
  • Reel Number -- ID # of the archival 16mm film print   
  • Date of Clip       
  • Product    
  • Company (if known)    
  • Notes   
  • Ad agency    
  • Hard drive  -- for production tracking 
To publish the collection in iTunes U, we added two more elements:
  • Album Id -- used to build RSS feeds for each album in iTunes U    
  •  I-Tunes Title -- constructed from other tags: Company: Product, Date of Clip (Filename)

Accessibility

Commercials in the Highlights album will receive captioning and video description by the Media Access Group of WGBH, which administers the National Center for Accessible Media. Commercials with accessiblity features will be added to the collection as they are completed.


Publication

To publish the collection in iTunes U, we created an album/course page in Duke's iTunes U site for each Product in the collection. Then, we mapped our metadata records to the iTunes XML tag set and generated RSS feeds for each album. More information about using RSS feeds with iTunes U can be found in the iTunes U Administrator Guide.

We also published the metadata on our own digital collections site to facilitate cross-collection searching and browsing. Search results for AdViews provide links directly to specific album pages within iTunes U.

More details coming soon...
