What is Omeka?
Omeka S is a web-based software that allows users to catalogue, archive, publish, and exhibit any data or media they want. Any information that you want to be publicly available is published on a site, which allows the public to browse and search through your resources, as well as access any pages you choose to create (such as a "welcome" page, online exhibits, general information). Omeka S allows for multiple “sites” to exist on one domain, allowing craftarchive.ca to hold an unlimited number of websites and repositories which work separately from each other.
Omeka sites are built using three basic concepts: Items, Item Sets, and Sites. Understanding how these three things work together will help you get a grasp of how Omeka can work for you.
