Repository software
Hyku is a feature-rich, robust, flexible digital repository that can be customized by and for institutions large and small. Hyku works well as a local installation or as a repository service hosted by a service provider or consortia. Hyku is built on top of the Hyrax repository engine so it comes with all of the features of Hyrax but adds additional customization and multi-tenancy. Being multi-tenant means that a single repository owner that can create multiple repository instances, for example creating and hosting repositories across a consortia or for multiple campuses. Hyku makes it easy to add and discover works with integrations like the IIIF Image & Presentation API, the Universal Viewer, and bulk import scripts as well as customization options like adding fonts and custom CSS.

Organizational Commitment to Community Engagement

Much of Samvera's development is driven by its Interest and Working Groups. These groups come together to discuss and work on matters of particular importance to the Samvera Community at any given time. Samvera's Interest and Working Groups operate in a transparent and inclusive manner. Each proposed new Group sets out a charter and posts an open invitation for participants from across the Community. Generally the meetings are held online and the minutes are posted on Samvera's wiki.

Additional Information

Organizational History

The Digital Public Library of America (DPLA), Stanford University and DuraSpace partnered to extend the existing Samvera community (formerly "Hydra project") codebase and its vibrant and growing community to build, bundle, and promote a feature-rich, robust, flexible digital repository that is easy to install, configure, and maintain. Initially developed under the “Hydra-in-a-Box” label, the product of this collaborative effort is Hyku, a next-generation repository solution. Hyku works for institutions large and small, incorporating the capabilities and affordances to support networked resources and services in a shared, sustainable, national platform. The overall intent is to develop a digital collections platform that is not just "on the web," but "of the web." With funding from the Institute of Museum and Library Services, the collaborative project kicked off in 2015. In 2017, Hyku entered beta, and in February 2019, it was promoted out of Samvera Labs. Ongoing development of Hyku is guided by the Samvera community via the Hyku Interest Group and associated partners.
