Omeka is a free and open-source web-publishing platform that specializes in displaying library, museum, archives, and scholarly collections and exhibitions. With its user-friendly interface and quick five-minute setup, Omeka makes it as easy to create an online archive or exhibition as it is to launch a blog. The name Omeka is derived from the Swahili word meaning to display or layout wares.

It reflects the platform's mission to help users showcase their digital content and build digital projects for online communities. Since its initial release in 2008, Omeka Classic has become a renowned open-source web publishing platform, downloaded over 500,000 times and used by libraries, archives, museums, scholars, and users worldwide. To enhance its functionality, Omeka offers a wide range of addons and plugins, including Geolocation, Contributions, and Neatline, developed by external developers in collaboration with the Omeka team.

Additionally, Omeka provides a hosted solution called Omeka. net, which offers cost-effective hosting for organizations and individuals who may not have the resources to run Omeka Classic on their own servers. With the continuous development of both Omeka Classic and the newer Omeka S, featuring enhanced scalability and integration with digital scholarly communications, Omeka remains at the forefront of web publishing platforms for digital collections
