Valkyrie for Hyrax has been a promise to Samvera users for a few years. So much excellent work has been done here, but community resources have been constrained to get it across the line. Completing this work would provide a number of important benefits to the community:

  • Long-desired options beyond Fedora 4 for existing Samvera users, including Postgres or Fedora 6 backed Hyrax

  • Removal of what has been a “let’s wait” blocker for institutions who have delayed upgrades

  • Attractiveness of Samvera solutions to potential adopting institutions who have been hearing about Valkyrie and waiting to act

  • Interest from service providers and a path to keep their engagement in the community viable


There are three main milestones that we as a community want to accomplish, to be targeted in this order of priority: 

  • Milestone 1 is to create a fully functioning version of Hyrax that is backed by Postgres. 

  • Milestone 2 is to pave a well-established workflow for live-migrating an existing Fedora 4 backed Hyrax repository to Valkyrie Postgres backed Hyrax repository. 

  • Milestone 3 is to have the Fedora 6 Valkyrie adapter fully working in Hyrax. 

There are two ways you can contribute to this work if Hyrax is important to your institution:

Contribute financially:

The Hyku for Consortia group (PALNI and PALCI) are leading a pledge drive to raise funds to support work sprints through SoftServ to move the Valkyrie for Hyrax work forward in a May-June 2023 series of sprints. The goal is to collect $50,000 - $100,000 in funds to move this work forward as soon as possible.
