I've started working on a project on local maritime history. The project covers several hundred years, and many themes including maritime industries, ships, notable people, ethnic groups, real estate, etc.
I came across the omeka-powered site Histories of the National Mall (http://mallhistory.org/), and I see some custom plugins were developed. I was wondering if those customizations were available to copy & modify, and also how much effort was involved in developing that site.
Thanks all
