Omeka.net provides a web-publishing platform to curate collections and create exhibitions of digitized content. Omeka.net has grown out of the Omeka project. Omeka.net provides some of the same functionality as Omeka, but does not require the user to provide hosting or to maintain their installation in any way. However, use of Omeka.net limits customization, and hosting more than 500MB of content requires a paid account.

Objects in the collection can be cataloged with Dublin core metadata fields and georeferenced for display on a map. Omeka.net includes several plugins, including COinS (which makes objects in Omeka accessible to citations management software, like Zotero), HTML5 Media (to play audio and video), and Library of Congress Suggest (which will auto-populate fields with LoC authority and subject headings).

Omeka is a content management system designed for the display of library, museum, archives, and scholarly collections and exhibitions.

Omeka falls at a crossroads of Web Content Management, Collections Management, and Archival Digital Collections Systems. Omeka is designed with non-IT specialists in mind, allowing users to focus on content and interpretation rather than programming. It brings Web 2.0 technologies and approaches to academic and cultural websites to foster user interaction and participation. It makes top-shelf design easy with a simple and flexible templating system. Its robust open-source developer and user communities underwrite Omeka’s stability and sustainability.

Omeka allows users to publish cultural heritage objects, extend its functionality with themes and plugins, and curate online exhibits with digital objects.
