A presentation given at the Open Repositories conference in 2010. In part, the proposal reads and While repositories provide obvious benefits in hosting and managing content, it is equally clear that there is no “one size fits all” solution to the range of digital asset management needs at a typical institution, much less across institutions. A system that supports the submission, approval and dissemination of electronic theses and dissertations, for example, has demonstrably different requirements than a digitization workflow solution, an e-science data repository, or media preservation and access system. There is a clear need in the repository community to readily develop and deploy content-, domain-, and institution-specific solutions that integrate the flexibility and richness of customized applications and workflows with the underlying power of repositories for content management, access and preservation. This paper will provide an overview of Hydra’s philosophy, architecture, and components, as well as demonstrations of various Hydra installations. The paper will also provide a progress report on Hydra development to date and its overall roadmap, as well as provide observations on the successes and challenges of community-based development of shared repository solutions.

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.

Open source software isn’t really free. This might seem obvious to some, but there are many members of open source communities that consume rather than contribute, Slides from a panel session given at the Open Repositories conference in 2015 held in Indianapolis described thus, and they use the software but are either unwilling or unable to engage with the community to write code, submit use cases, create documentation, or do any of the other things that make an open source project a success. Fortunately, things don't have to be this way. Over the past two years, the Fedora project has undertaken a great effort to revitalize not only the software but the community itself. By maintaining open, transparent communication, soliciting use cases, development, and testing from community members, and establishing a clear project governance structure, we have laid the groundwork for a successful community source project. At the same time, the Islandora and Hydra communities have pursued similar strategies to build and sustain their own communities and the broader Fedora community. This panel will feature a discussion on the recent successes of the Fedora community and future plans to continue raising the level of community engagement and project ownership.

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.

A lightning talk at Samvera Virtual Connect 2018 described thus and Beginning in April, folks from DuraSpace, Stanford University, Digital Curation Experts, CoSector (U. of London), Ubiquity Press, Texas Digital Library and Notch8 have been meeting to discuss their experiences hosting Hyku and develop a roadmap for its future. This presentation will update the Samvera community on the work group members have done to host and implement Hyku, plans for future work, and present several topics for consideration such as a potential governance structure and the feasibility of Hyku going forward.

Fedora, the flexible, extensible, open source repository platform for managing, preserving, and providing access to digital content, is a key component of most Samvera implementations. Fedora 4.x, the latest version of Fedora, has been in production since 2015, and since then the real-world experience of the community’s use cases has clarified Fedora’s role in supporting preservation and access in the context of large collections and performance at scale. This understanding led to an effort to formally specify the Fedora application programming interface (API) that provides a stable layer of abstraction between clients and repository instances. In this way, alternate back-end implementations suited for specific user cases can all expose the same core services to repository clients. This initiative will allow the Fedora project to adapt to technological change more easily over time while insulating clients from changes in the underlying implementation. This presentation will provide an overview of the the API specification effort, including current status, motivations, and benefits, with a particular focus on the relevance to Samvera. A brief survey of alternate implementations will provide context for the different use cases that will be enabled by the specification. This will be of interest to current and future Fedora implementers looking for an update on the current status and technical roadmap of the project.
