In recent years, concern over the longevity of physical audio and video (AV) formats due to media degradation and obsolescence, combined with decreasing cost of digital storage, have led libraries and archives to embark on projects to digitize recordings for purposes of long-term preservation and improved access. IU's Media Digitization and Preservation Initiative (MDPI) is one of those projects, estimated to digitize 325,000 audio and video items and 25,000 film items overall. Beyond digitization, in order to facilitate discovery and research use, AV materials must also be described, but many items and collections lack sufficient metadata. Join us to learn more about a planned project at IU with experts from University of Texas at Austin School of Information and AVP to create a technology platform and workflow to support the incremental application of both automated and human-based processes to create and augment metadata at large scales for AV collections. The project is called AMP: Audiovisual Metadata Platform.
Audiovisual archivists agree that media holdings must be transferred to the digital domain as soon as possible in order to survive. Because this work requires significant resources, it must be conducted as efficiently as possible. One place to realize efficiencies is in the management of the digitization process. This presentation will explore managing effective and efficient 1:1 as well as parallel transfer media digitization workflows. Using the Indiana University Media Digitization and Preservation Initiative project as a case study, Mike Casey will discuss applying the theory of constraints and adapting software development methodologies to efficiently manage 1:1 digitization workflows. This will include a look at working with bottlenecks, scrum methodology, and the daily standup. Andrew Dapuzzo from Memnon Archiving Services will address issues in regulating parallel transfer workflows including the role of workflow management software, the importance of both human and machine quality assurance in each step of the process, the difficulty in maintaining obsolete machines, overall system design and Total Quality Management. The more efficient the digitization workflow, the more we are able to preserve with scarce resources.
Indiana University announced the Media Digitization Preservation Initiative (MDPI) in October 2013 with the goal of digitally preserving and providing access to all significant audio, video, and film recordings on all IU campuses by the IU Bicentennial in 2020. Digitization began in mid-2015 and has now digitized more than 320,000 objects using more than 10 petabytes of storage. After digitization, every object in MDPI has to be verified to be stored correctly, checked for format conformance, processed into derivatives, and finally, distributed to a streaming video server. Conceptually, the process is straightforward, but like many things, the devil is in the details. The post-digitization processing has continually evolved since its inception in early 2015. Initially implemented to handle a couple of audio formats and processing a few terabytes of data per day, over the last few years it has been enhanced to handle peak transfers of more than 35 terabytes daily with more than 20 formats across audio, video, and film. This presentation details how some of the implementation decisions have held up over time, such as using a tape library as primary storage and using an object state machine for object tracking, as well as some of the growing pains encountered as the system was scaled up. In addition, there is a discussion covering some of the surprises that have been encountered along the way.

Summary:
The Indiana School of the Sky radio program of the Indiana University Department of Radio and Television began broadcasting educational radio programs in 1947 and continued through the early 1960s. The program reached schools throughout Indiana and nearby states and led to new course offerings at IU. Indiana University students performed in the radio programs originally intended for children ages 4-8 aired for 15 minutes during each school day. Eventually the popularity of the programs called for high school programming as well, and later adults also tuned into the programs. This collection contains recordings of these programs.
