title: Protecting the Long-Term Viability of Digital Composite Objects through Format Migration
creators: Elizabeth Roke Dorothy Waugh
abstract: This poster documents work recently undertaken at Emory University’s Manuscript, Archives, and Rare Book Library (MARBL) to review policy on disk image file formats used to capture and store digital content in our Fedora repository. Survey of the field and current best practices revealed waning support for the formats previously used and prompted collaborative efforts between Digital Archives staff and software engineers to migrate existing disk images to formats now deemed more suitable for long-term digital preservation.
