Omeka ("Oh-meh-kah") is an open-source web publishing platform for sharing digital collections and creating media-rich online exhibits. It is widely used by archives, historical societies, libraries, museums, researchers and teachers to create searchable digital collections.
Omeka was developed by the Roy Rosezweig Center for History and New Media beginning in 2006. Omeka is a non-profit project supported by a community of open source developers.
