What is Hyrax?

Hyrax is a Ruby on Rails Engine built by the Samvera community. Hyrax provides a foundation for creating many different digital repository applications.

Note: As a Rails Engine, Hyrax is not a web application. To build your digital repository using Hyrax you must mount the Hyrax engine within a Rails application. We call an application that mounts Hyrax a "Hyrax-based application" (or sometimes a "Hyrax Application").

Hyrax offers the ability to:

  • Create repository object types on demand
  • Deposit content via multiple configurable workflows
  • Describe content with flexible metadata
  • Enable/disable optional features via an administrative dashboard
  • And more (https://hyrax.samvera.org/about/)
