Overview
Samvera Hyrax is a free, open-source Ruby on Rails engine, created in December 2016 by consolidating the earlier Sufia and CurationConcerns gems, that gives libraries and archives a foundation for building digital repository applications. It is maintained by the Samvera community, which originated in 2008 as the Hydra Project and was renamed Samvera in May 2017.
Key Features
Hyrax provides deposit and metadata workflows, a works-and-collections data model, role-based access control, batch operations, and a configurable public discovery interface out of the box.
Since Hyrax 5, the framework supports the Valkyrie data mapper, removing the hard dependency on the Fedora repository server so institutions can choose their own persistence and storage back ends.
Pricing
Hyrax is free and open source under the Apache License 2.0, with no vendor pricing; institutions typically need in-house Ruby on Rails developers or a hosting partner to deploy and maintain it.
Key Features
Deposit and Metadata Workflows — Configurable deposit forms and metadata schemas for describing digital objects and collections.
Works and Collections Model — Built-in data model for organizing individual works into collections with relationships between items.
Access Control — Role- and group-based permissions for controlling who can view, edit, or manage repository content.
Batch Operations — Tools for bulk-editing metadata and managing large sets of objects at once.
Configurable Discovery Interface — A public-facing search and browse interface that institutions can customize and brand.
Valkyrie Data Mapper Support — Since Hyrax 5, a decoupled persistence layer that removes the hard dependency on the Fedora repository server.
Samvera Ecosystem Compatibility — Interoperates with other Samvera community tools and gems, including the multi-tenant Hyku distribution.
Apache 2.0 Licensing — Fully open-source licensing that allows institutions to freely deploy, modify, and extend the codebase.
