Omeka screenshot

Omeka is an open-source, PHP-based web publishing platform for managing, publishing, and exhibiting metadata-rich digital collections. It ships in two primary distributions — Omeka Classic for individual projects and educators, and Omeka S for multi-site and institutional deployments — and is extensible via themes, plugins (Classic) and modules (S).

Key Features

  • Core support for structured metadata (Dublin Core and custom mappings) and item/collection (Classic) or item/item set/resource templates (S).
  • Extensible architecture: installable plugins (Classic) and modules (S) plus custom themes to change site presentation and behavior.
  • RESTful API endpoints for programmatic access and integrations; support for JSON-based services and interoperability features.
  • File storage adapters including local filesystem and S3-compatible storage, plus support for image derivatives and thumbnailing via GD or ImageMagick.
  • User roles and permissions for administrators, contributors, and public access; site-building tools in Omeka S for multi-site resource sharing.
  • Wide third-party ecosystem: modules for IIIF/Universal Viewer, CSV import/export, SPARQL and cloud storage adapters.

Use Cases

  • Museums, libraries, and archives publishing curated digital exhibits and searchable collections.
  • Academic and digital humanities projects for teaching, student projects, and research-focused collections.
  • Institutions running multiple branded sites that share centralized resources and vocabularies (Omeka S).

Limitations and Considerations

  • Feature sets and plugin/module ecosystems differ between Omeka Classic and Omeka S; migrating or mixing distributions requires planning and testing for compatibility.
  • Some advanced modules and background jobs require additional server tools (PHP-CLI, ImageMagick, poppler-utils) and specific PHP/database versions; administrators must meet system requirements and manage updates accordingly.

Omeka is well-suited for organizations that need a metadata-first, extensible platform for digital collections and exhibits. It emphasizes interoperability and an active community ecosystem while requiring standard web hosting administration to deploy and maintain.

Omeka S is a modular PHP-based web publication system designed for museums, galleries, libraries, archives, and other cultural heritage institutions. It lets organizations create independently curated exhibits that draw from a shared pool of items, media, and metadata across a local network of sites.

Key Features

  • Modular architecture with cores, modules, and themes to extend functionality and presentation
  • Centralized item and media repository usable by multiple exhibits/sites with shared metadata management
  • RDF/linked-data support and metadata modeling for controlled vocabularies and semantic interoperability
  • Built-in exhibit and resource management features tailored for collections and archives
  • Support for common PHP libraries and tooling (Doctrine ORM, Laminas components) and front-end build tooling via npm
  • Thumbnail/image generation and media handling (ImageMagick recommended)

Use Cases

  • Publish curated online exhibits that aggregate items from a shared institutional collection
  • Manage and present digital collections with descriptive metadata and controlled vocabularies
  • Provide a lightweight institutional repository for galleries, university archives, and special collections

Limitations and Considerations

  • Requires a PHP/Apache/MySQL or MariaDB stack and server configuration (PHP 8.1+ recommended)
  • Performance and scalability for very large collections may require tuning and more robust infrastructure
  • Feature availability often depends on community modules; some integrations may need custom development
  • Thumbnailing and advanced media processing rely on external tools and correct server setup

Omeka S is focused on cultural heritage publishing and metadata-driven collection management rather than general-purpose CMS features. It is well suited for institutions needing exhibit-centric workflows and semantic metadata support.

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.
