After 5 years of work, we are very pleased to publish our Repository Design Report, which describes the architecture and design of the PDPTV model preservation repository!

Developed by the Digital Library Technology Services team at New York University, the repository provided an important testbed and prototype for digital preservation of complex video files and their associated metadata. Thanks to the Library of Congress, we know that this work is going to advance the design and creation of “trusted” digital repositories for public broadcasting and related media content.

The report describes:

  • The design of the preservation environment;
  • The technologies used to support preservation functions;
  • The creation of Archival Information Packages for managing complex video files;
  • The standards used to support aggregation of disparate sources of metadata, including METS, PBCore, and PREMIS;
  • And the process used to determine needs of repository users in order to design output requirements.

This report was written by NYU Software Systems Architect Joseph Pawletko, with contributions by Nan Rubin (WNET) and Kara Van Malssen (NYU).  Thanks to all PDPTV team members and fellow travelers for their input and collaboration, without which we could not have produced this caliber of work.  Also thanks to the NDIIPP program at the Library of Congress for their consistent support and confidence in our project.
