Omeka

What Omeka does

Omeka is an open-source web publishing platform purpose-built for libraries, archives, museums, and digital humanities scholars to share digital collections and create media-rich online exhibits. The platform is offered in two core variants: Omeka Classic (released February 2008) for individual projects and educators, and Omeka S (launched October 2012) for institutions managing multiple sites from a single installation. The technology is built on PHP with MySQL/PostgreSQL support, adhering to Dublin Core metadata standards for interoperability. Omeka S extends the architecture with JSON-LD as its native data format and RDF vocabularies, enabling integration with the Linked Open Data ecosystem. The product suite is extended by approximately 100 community-developed plugins (ExhibitBuilder, Geolocation, Zotero Import, IIIF Toolkit, OAI-PMH Harvester, Neatline geospatial suite, etc.) and 17+ themes, with internationalization across dozens of languages via Transifex. Omeka.net, launched in 2010, provides a hosted service alternative for users without server management capability and has hosted nearly 83,000 users and 50,000+ sites. Omeka Services provides paid training (offered three times annually), direct support, isolated managed hosting, and custom development. The project has been downloaded over 500,000 times since 2008. Since 2016, Omeka has operated under the fiscal stewardship of Digital Scholar (Corporation for Digital Scholarship), a nonprofit organization based in Vienna, Virginia. The platform's sustainability is supported by grants from IMLS, Mellon Foundation, Library of Congress, Sloan Foundation, NEH, Getty Foundation, and Kress Foundation, combined with fee-based services and Omeka.net subscriptions. The core team comprises approximately 10 staff members under Director Sharon Leon (also COO of Digital Scholar) and Lead Developer John Flatness.

Broad incumbents

• WordPress: General-purpose open-source CMS with extensive plugin ecosystem that can be extended for digital collections and exhibit publishing. Competes with Omeka for individual educators, students, and smaller institutions needing simple web publishing, though lacking Omeka's built-in Dublin Core metadata standards.
• Drupal: General-purpose open-source CMS that can be configured for digital collections and exhibits with custom modules. While not specialized for LAM like Omeka, it competes for the same institutional web-publishing budgets and is the foundation for several LAM-specific platforms like Islandora.

Emerging players

• Mukurtu: Open-source platform designed for Indigenous communities to manage and share digital cultural heritage with culturally sensitive access protocols. Overlaps with Omeka's cultural-heritage digital collection use cases while addressing a specialized segment with unique community-driven governance features.
• Scalar: Open-source digital publishing platform designed for long-form, media-rich scholarly publications from the Alliance for Networking Visual Culture. Overlaps with Omeka's media-rich exhibit capabilities for digital humanities scholars, though focused more on nonlinear scholarly narratives than collection management.

Direct peers

• CollectiveAccess: Open-source collections management and publishing software used by museums, archives, and galleries to catalog and publish digital and physical collections. Directly comparable to Omeka in the GLAM space, serving similar customers with overlapping metadata and publishing workflows.
• ContentDM: OCLC's digital collection management software widely used by libraries, archives, and museums to build and publish digital collections. It is the most direct commercial competitor to Omeka in the LAM digital-publishing space, serving the same institutional customers with overlapping functionality.
• DSpace: Open-source institutional repository platform widely used by academic libraries for managing and publishing scholarly outputs and digital collections. Competes with Omeka for institutional repository use cases, though more focused on research outputs than curated digital exhibits.
• ArchivesSpace: Open-source archives management application serving the archival description and public access needs of archives and special collections. Comparable to Omeka as a LAM-sector open-source platform, though focused on archival description rather than digital exhibits.
• Islandora: Open-source digital asset management and repository platform built on Drupal, used by cultural heritage institutions for managing and publishing digital collections. Comparable to Omeka S in targeting institutional repositories with linked data and multi-site capabilities, and competing for the same grant-funded cultural-heritage deployments.
• Hyrax / Samvera: Open-source digital repository framework built on Ruby on Rails, used by academic and cultural institutions for managing digital collections with linked data support. Directly comparable to Omeka S in the institutional digital repository space with overlapping target customers.
