Hyrax uses the full power of Samvera and extends it to provide a user interface around common repository features and social features. Hyrax offers self-deposit, proxy deposit, and mediated deposit workflows. Hyrax delivers its rich and growing set of features via a modern, responsive user interface.

Hyrax was created through the consolidation of the Sufia and CurationConcerns gems. (Sufia was originally developed at Penn State University as a shareable generalization of their Samvera-based research repository application, ScholarSphere.)

Hyrax, and Sufia and CurationConcerns before it, has been maintained by a growing number of Samvera community developers (with over 110 contributors as of April of 2018.

Hyrax is exemplary of Samvera development that has had wide implementation and code contributions to become a truly community-driven, -supported, and -maintained solution bundle.

eScholarship – scholarly publishing and repository services

eScholarship, provides scholarly publishing and repository services that enable departments, research units, publishing programs, and individual scholars associated with the University of California to have direct control over the creation and dissemination of the full range of their scholarship.

eScholarship Publishing

eScholarship Publishing provides comprehensive publication services for UC-affiliated departments, research units, publishing programs, and individual scholars who seek to publish original, open access journals, books, conference proceedings, and other scholarship. Our journals program, in particular, supports publications that traverse standard disciplinary boundaries, explore new publishing models, and/or seek to reach professionals in applied fields beyond academia.

eScholarship Repository

eScholarship Repository offers preservation and dissemination services for a wide range of scholarship including working papers, electronic theses and dissertations (ETDs), student capstone projects, and paper/seminar series. eScholarship Repository is also the primary destination for researchers depositing their previously published journal articles in accordance with the Academic Senate’s UC Open Access Policy.

Samvera; Repository Framework

Samvera is an Open Source Repository Framework

Samvera software was conceived as an open source repository framework.  That is to say that we set out to create a series of free-to-use software “building blocks” that could put together in various combinations to achieve the repository system that an institution needed – as opposed to building a “one size fits all” solution.

The framework as it exists today consists of a number of Ruby gems that can be combined, configured and adapted to serve a wide variety of needs, as you can see on our “applications and demos” page.  Some of our adopters started with just the basic building blocks, but then a more common approach became to find another institution whose use case was similar, clone their Samvera variant and then adapt it to more closely fit local needs.

Using the Samvera framework in this way potentially allows an institution to build for themselves a repository solution closely fitted to their needs, however the building process and later the maintenance of such a customized system can be resource intensive.  In the last few years the Samvera Community has seen an emerging need for some off-the-shelf “solution bundles”, addressing particular needs, that can be installed and maintained with fewer local resources – or that can be deployed as a hosted, cloud service.  The Community has responded to this need with three such bundles, built using the standard Samvera framework, which are currently in various stages of development:

  • Avalon – a time-based media solution
  • Hyrax – is a Ruby gem that includes much of Samvera’s functionality.  It is the basis on which users can build their own, customized version of Samvera.
  • Hyku – the product from the “Hydra-in-a-Box” project. The Digital Public Library of America (DPLA), Stanford University and DuraSpace have partnered to extend the existing Samvera codebase to build, bundle, and promote a feature-rich, robust, flexible digital repository that is easy to install, configure, and maintain. Hyku can be installed locally or run in the cloud and is based on Hyrax.  A number of service providers, including DuraSpace themeselves, are – or will soon be – offering cloud-based, hosted versions.

All Samvera’s software is free and open source, available under an Apache 2 license.

DASH; Open Access Repository

What is DASH?

A central, open-access repository of research by members of the Harvard community.

DASH enlarges the audience and impact of your work. Authors who deposit in DASH have access to on-demand metrics and receive monthly reports about their readership. Deposited works receive persistent URLs, are comprehensively indexed by search engines, including Google and Google Scholar, reach academic and non-academic readers who may not have access to the original publications, and are preserved by the Harvard Library.

Making your work open access in DASH is as simple as completing our quick submit form. We also welcome bulk deposits and offer CV scraping services. Simply contact OSC if you are interested. OSC will do the legal legwork for all submissions.

The OSC is pleased to offer a robust suite of services to support you and your scholarship. Visit our For Authors page to learn more.
