  • Automated “tidy” workflows to reorganize and rename files on disk based on metadata
  • Troubleshooting tools to identify duplicates, nested models, and inefficient formats
  • Background job processing for asynchronous tasks (such as processing and analysis)

Use Cases

  • Build a searchable home archive of 3D printing models for a makerspace or personal library
  • Maintain a team collection of approved print files with consistent metadata and naming
  • Publish selected models publicly while keeping private collections restricted

Limitations and Considerations

  • Federation features are present but may require additional setup and operational understanding

Hyrax

Hyrax

Open-source repository engine from the Samvera community for building institutional digital repositories with flexible metadata, workflows, and search integration.

Hyrax screenshot

Hyrax is a Ruby on Rails repository engine developed by the Samvera community that provides a foundation for building customizable digital repositories and collection front-ends. It supplies domain-specific features and UI components while letting implementers choose how to mount Hyrax inside a Rails application and which persistence and indexing backends to use.

Key Features

  • Rails engine architecture that is mounted inside a host Rails application, enabling reusable repository components and extension points
  • Flexible metadata modeling and configurable work/object types to represent diverse collection items
  • Configurable deposit and review workflows, role- and group-based access controls, and administrative dashboards
  • Support for multiple persistence/indexing adapters (Valkyrie-based adapters) allowing Postgres or Fedora for metadata and Apache Solr/Blacklight for search
  • Background job support and activity streams integrations (Redis-backed queues such as Sidekiq are commonly used)
  • Media derivative generation and processing integrations (image and document derivatives, thumbnailing, and media processing)
  • Development and deployment tooling included: Docker / docker-compose support and JavaScript tooling for front-end assets

Use Cases

  • Institutional repositories and academic library collections for preserving and exposing scholarly outputs and archival materials
  • Digital asset management for library/archives collections that need flexible metadata, workflows, and discovery interfaces
  • Project-specific or departmental digital collections that require custom metadata profiles, moderation workflows, and search-driven discovery

Limitations and Considerations

  • Significant infrastructure and integration needs: a Hyrax deployment typically requires additional services (search index, database, Redis, media tools) and configuration effort
  • Requires substantial Rails development and Samvera-specific knowledge for non-trivial customizations, upgrades, or adapter changes
  • Because Hyrax is a feature-rich framework, deployments can be complex to tune for high-scale performance and may require careful planning of indexing and background-job strategies

In summary, Hyrax is a mature, community-maintained framework for building institutional digital repositories with strong metadata, workflow, and search capabilities. It is most appropriate for institutions that can invest in the required infrastructure and Rails development to customize and operate a production repository.
