A presentation given at the Open Repositories conference in 2009. Part of the proposal reads and Repositories have proven themselves as powerful tools for managing digital content in many different contexts. But experience has also shown that there are real, practical limits in trying to extend a single repository solution to meet the manifold needs of most institutions for their full range of digital content and use cases. Relatively narrow and inflexible application front ends can be used to create single-purpose repository-powered solutions, but they do not lend themselves to being quickly and easily repurposed to meet variations in content type or user interactions. There is a clear business need for a flexible, reusable application framework that can support the rapid development of multiple systems tailored to distinct needs, but powered by a common underlying repository. Recognizing this common need, Stanford University, the University of Hull and the University of Virginia are collaborating on “Project Hydra”, a three-year effort to create an application and middleware framework that, in combination with an underlying Fedora repository, will create a reusable environment for running multifunction, multipurpose repository-powered solutions. This presentation will provide demonstrations of the work done to date, including of the prototype ETD application, as well as the set of content models and disseminators that the project has defined so far. The presentation will also present links to the project’s publicly accessible documentation and open source code, as well as solicit the constructive input from community members who may be interested in the project or its outcomes.
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.

At the Digital Collections and Archives (DCA) at Tufts University we have designed, built, and integrated our archival collection management system and repository’s administrative interface to facilitate ingesting archival objects into our Fedora based repository. This 24x7 session briefly explores the assumptions and functional requirements we have used to guide this development work. The DCA’s unique position as an archives that is one of the key stakeholders and users of the Tufts institutional repository has enabled us to meet this integration challenge. The session describes how the integration of our archival collection management system and our repository relies on the ability to flexibly move metadata from one system to another. and A lightning talk given at the Open Repositories conference in 2015 held in Indianapolis described thus
A panel presentation given at the Open Repositories conference in 2015 held in Indianapolis described thus and Partnerships for shared repositories offer the promise of repository services at a decreased cost due to shared infrastructure and staff. In practice, reduced costs for shared repositories often require tradeoffs in security or access for the shared system. Staff working in a shared system may be geographically distributed or may work for different institutions with different priorities and reporting lines. Effective use of shared services requires thoughtful communication and tools that help maintain consistency and prevent conflicts when multiple people work in the same system. In this panel, shared repository service managers for multisite Islandora installations and a Hydra partnership will discuss methods for distributing system access and communicating with staff who work at our parent organizations, partner institutions, and third-party vendors. Each panelist will discuss the methods used so that distributed staff can have the level of access necessary to use the repository’s unique functions, while also ensuring that widely distributed system access doesn’t result in data loss or system failures.
Indiana University and Northwestern University, in collaboration with nine partner institutions, recently completed the last year of a three-year IMLS-funded effort to build the Avalon Media System, an open source solution for managing and providing access to digital audio and video collections, based on Fedora and the Hydra repository software development framework. As the Avalon platform reaches maturity, several institutions are in the process of implementing Avalon both to replace current time-based media access solutions and to support new use cases. In addition, new funding from the Andrew W. Mellon Foundation will support continued work to develop new features, grow and provide support for the community of adopters, and move Avalon towards organizational and financial sustainability. This panel will bring together project leaders from Indiana and Northwestern, along with Avalon community members at the University of Virginia and Stanford University, to share experiences of implementing Avalon at their institutions, integrating Avalon with other local systems, and supporting Avalon to enable a variety of use cases in research, teaching, and learning. Panel members will also discuss future development plans and provide a preview of how the project intends to transition from a grant-supported endeavor to a community-sustained solution. and Slides for a panel presentation given at the Open Repositories conference in 2015 held in Indianapolis described thus
This presentation was given during the Samvera Partners' call on 14th August 2020. It describes a collaboration between George Washington University and the New York Times to make available administrative documents discovered after the Islamic State withdrew from Mosul in Iraq. The collaboration is using using a Hyrax-based repository.

* Understand what Samvera is and how to participate * Understand how to use Samvera * Understand the value of Samvera Samvera is a community, a set of tools, and a collection of ready-to run and hosted applications to help build a digital repository for your institution. The community drives the specification and development of sustainable open source technology and honing best practices for managing digital content. This workshop will provide an on-boarding and general entrée to the Samvera community and solutions for non-coders. The first part will provide an overview of Samvera solutions, hosting options and the community – what is it, why is it different? It will showcase applications solving a diverse set of needs and organizations, and discuss the how the community at large works to enable these. The second part will give a general technical overview designed for a non-technical audience. The resources needed to maintain and contribute to a hosted or custom Samvera solution will be discussed, resources that exist to get started will be highlighted plus how to contribute to the community technically and non-technically. The final part will discuss value and how to pitch Samvera and get institutional support. It will discuss the advantages of being part of the community and how that strengthens the sustainability of the tools, the applications, and the community overall.

A presentation given at Samvera Connect 2020 On-line described thus and Collaboration is more than just sharing costs, and the PALCI and PALNI consortia are pushing that idea into our repository management. We want to create the flexibility for both IR workflows and more “traditional” library-owned content within the same instance of Hyku. We also want to enable libraries to collaborate and share work, not just with their consortial partners, but also among their own departments across campus. To us, this means enhancing the ability to manage user and tenant settings to enable different workflows. By working with a number of libraries testing out the Hyku multi-tenant option, we realized that a robust dashboard for user/role assignment and the expansion of a few more roles would enable us to manage these flexible workflow options. PALNI and PALCI are working with Notch 8 to enhance the underlying “role” and “group” functionality in Hyku and develop a new administrative dashboard to control permissions across multiple tenants. We will also be expanding role and group functions within tenant management. This presentation will discuss how we researched and developed our requirements as well as the plan and progress to date.

Our Samvera-based institutional repository is nearing eight years old, and one can safely say it is middle aged-- and with middle age comes a mid-life crisis. Over the course of the past year, the current product owners have examined the role and vision of the repository and embraced the role of maintainers, advocating for critical external needs. Balancing the technical needs and costs of an aging system while providing new services to meet user needs with a limited technical staff has required being realistic about both available resources and institutional priorities. In this talk, we will discuss our experiences, our methods for refining the focus of a large project, focusing developer work to yield maximum payoffs, and centering the repository to be more useful to the campus community by meeting users where they are.

A presentation at Samvera Connect 2019 described thus and This presentation will be a high level overview of the University of Michigan Library's plans for repository technology development. Themes, principles, and plans will be shared. We are continuously challenged to expand our capabilities and extend our reach to match the rapid evolution of research and scholarship in the digital age. We have seen unprecedented rates of content growth in recent years as our campus partners have also advanced in the digital realm. It is no longer just about texts and images. Research data, audio, moving images, and all kinds of complex born-digital materials like enhanced e-books have entered into the scene. The Library has very intentionally placed itself in the center of campus activities for more than two decades. We aspire now, as much as ever, to provide innovative solutions for this unique set of circumstances and uphold our commitments far into the future. We are building next generation infrastructure for digital preservation and access that is adaptable, scalable and sustainable as the needs of campus continue to change.
This session will present a case study of Lafayette College’s repository migration project. We will share our experience modeling, developing, and migrating to a custom Hyrax implementation with a lightweight team of one librarian and one developer working within a small liberal arts college context. The first phase of this migration project centered on text-based digital collections, including college newspapers, magazines, and faculty scholarly output, while future work will focus on migrating image collections into the repository. and A presentation at Samvera Connect 2019 described thus
In 2006, Stanford Libraries built the Stanford Digital Repository (SDR). The system has served us well—thirteen years later, SDR contains over 2.0 million objects (~500 terabytes of content). We built SDR using open-source software (including Samvera, Fedora, and Blacklight) and an additional ~300,000 lines of custom code. We believe it is among the largest and most complex repository systems in research libraries, and yet the challenges we face are common. We have grown SDR to a point where it is extremely difficult for us to sustain. Some of our foundational technologies are not only aging but are beyond end-of-life. Meanwhile, we are challenged to continue offering a valuable, performant, highly-available repository service to our stakeholders. Over the past two years, we have analyzed the factors complicating sustainability, that work has led to operational changes that improve the current state and a plan for sustaining repository development combining open-source and custom software. Our presentation highlights the reasons SDR became unsustainable and shares areas where we have made improvements and where we go next. We believe the lessons we have learned are widely applicable to institutions that develop their own repository solutions., and A presentation at Samvera Connect 2019 described thus

A presentation at Samvera Connect 2019, originally titled "Creating a new Carolina Digital Repository, customizations and change", described thus, and In June 2019, the University of North Carolina at Chapel Hill University Libraries Software Development and Repository Services departments launched the new Carolina Digital Repository (CDR) platform, built on Hyrax. The new repository houses scholarly materials in support of UNC’s Open Access policy and supports many existing workflows and use cases such as student papers, OA books, and datasets. In this presentation we will describe existing and new use cases and show how we customized Hyrax to meet those needs. We will also share lessons learned and future plans for the CDR.
This presentation aims to explore the possible integration of Samvera digital object repositories with additional web services using message brokers. There have been cases in which it is necessary to synchronize content updates between repositories and additional library systems such as library catalogs or digital exhibit publishing software. Within this context, developers may benefit by exploring architectural pattern in which a dedicated message broker receives asynchronous notifications of repository content updates, new ingestions, and deletions. In response to having received these messages, the broker may then broadcast these events to other listening library systems. The library systems then may reindex or update their own content accordingly. A conceptual overview of this architectural pattern shall be provided, followed by an overview of an implementation local to the systems within the Princeton University Library (synchronizing content between implementations of Valkyrie and Spotlight using RabbitMQ). The outcome of this presentation would be to identify other Samvera adopters who may also be utilizing message brokers, with the ultimate aim of determining whether or not this approach would be beneficial to a larger number of community members.
