Why are we doing a community funding pledge to move forward on Valkyrization?

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

Valkyrize Hyrax Deliverables:

  • Milestone 1. Create a fully functioning version of Hyrax that is backed by Postgres.  This is work that will be accomplished within the nurax-pg/koppie test app environment.  Acceptance criteria:
    • CRUD and display of Collections/Works/Fileset/Files is complete. Files are the main missing piece here, but there is some work in progress already.
    • IIIF manifests are generated and displayed via UniversalViewer.
    • Object permissions/visibility/embargoes are all working properly.
    • Admin Sets/workflows are working.
    • Specs are updated to pass in this environment (the *-valkyrie tests run on CircleCI still have ActiveFedora in the mix)
    • Anything required to start work on the other milestones.

If there are funds and time remaining:

  • Milestone 2. Pave a well-established workflow for live-migrating an existing Fedora 4 backed Hyrax repository to Valkyrie Postgres backed Hyrax repository. 
    • Hyrax/Bootstrap/Rails
    • valkyrization could be done here to create a path for upgrade from a fedora 4 backed Hyrax instance that also supports Hyku

Note: Milestone 3 (have the Fedora 6 Valkyrie adapter fully working in Hyrax) will be carried forward by subsequent sprints in late summer/fall

Ticket Board: 

Other Contributions Needed:

  • An active, populated Hyrax repository for testing purposes
  • Testers, which is an excellent opportunity for non-developer library staff to contribute
  • A current Hyrax user willing to participate in sprint meetings
