Omeka is a free, open-source platform for building online exhibits and creating digital collections. It was created and is regularly updated by the Roy Rosenzweig Center for History and New Media. Intended as an inexpensive option for museums, libraries, archives, educators, and other institutions on a small budget, Omeka is designed to be easy to use and maintain with minimal resources.
There are several versions of Omeka available, with Omeka S and Omeka.net being the two most common. Omeka.net is unique in that part of the purchased package includes server storage for your data. This is the option the University of Texas at Austin Libraries have chosen. Each location that wants access to Omeka has their own Omeka site, over which they control the content and appearance. This gives UT's various repositories the ability to exercise greater control and include more content than if the Omeka site were centralized.
UT Libraries is currently planning a Data Asset Management System, and we are trying to make our metadata as easy as possible to map to the future DAMS. Omeka uses the Dublin Core Standard for metadata, while the UT DAMS will use MODS. In planning for the metadata to be entered into Omeka, the UT Libraries developed a standard that should make the mapping easier when content is copied into the DAMS.
Overall, Omeka provides an easy-to-use platform for exhibits for the UT Libraries and institutions. Hopefully this LibGuide will prove to be helpful in making the most of this tool!
