The Emory Libraries implemented a second-generation preservation infrastructure in 2019 utilizing Hyrax 3, Fedora 4 and AWS, following a requirements gathering phase that included developing a preservation policy and a review of preservation community best practices. This presentation describes our solution design including locally-defined entities such as preservation workflows and events and FileSet expansion to support derivative files. We will also address implementation lessons learned while leveraging existing Samvera functionality and building new features to bridge gaps between existing framework components.

Fedora 6, the next major version of Fedora, will focus on digital preservation by aligning with the Oxford Common File Layout (OCFL). The OFCL is an application-independent approach to the storage of digital objects in a structured, transparent, and predictable manner. This provides many benefits, including, storage diversity, to ensure content can be stored on diverse storage infrastructures including cloud object stores, parsability, both by humans and machines, to ensure content can be understood in the absence of original software, robustness against errors, corruption, and migration between storage technologies, versioning, so repositories can make changes to objects allowing its history to persist, and and completeness, so that a repository can be rebuilt from the files it stores. This presentation will provide an overview of the Fedora 6 design, including a brief introduction to the OCFL and how it is being implemented, along with a summary of development progress to date and the anticipated timeline for the 6.0 release.

A lightning talk at Samvera Virtual Connect 2019 described thus and For the past several years the Fedora community has prioritized alignment with linked data best practices and modern web standards. We are now shifting our attention back to Fedora's digital preservation roots with a focus on the Oxford Common File Layout (OCFL). The OFCL is an application-independent approach to the storage of digital objects in a structured, transparent, and predictable manner. Fedora 6.0, the next major release, will replace the current ModeShape backend with a more scalable and performant implementation that persists data in accordance with the OCFL specification. This presentation will provide an overview of the Fedora 6.0 design, including an introduction to the OCFL and how it will be implemented. It will be of interest to Samvera community members who want to track Fedora developments and understand their impact on Samvera applications.
