A former colleague, now a professor and researcher at the University of Wisconsin, Milwaukee, reached out to me about customizing the look and feel of an Omeka site he started building with students in a public history course. The site catalogs the religious history of Milwaukee in the built environment, relying heavily of maps, images, and sounds.
Omeka bills itself as the “Wordpress” for online collections and exhibits. It is frequently used by libraries, musuems, and humanists to mount projects like this one.
The project evolved into a complete custom theme for the site. The theme is licensed under the GPL 3.0 open source license and is available to browse (and download) on Github.
