I am a librarian and new to Omeka S. I am trying to import MODS as a vocabulary in order to add library-related bibliographic fields to our Resource Templates. These are fields that are not found in Dublin Core or we cannot use the DC field for more than one purpose , for example “Type” as the DC use of “type” but also as “genre,” in the bibliographic sense of the term. We also wanted to include staff notes and public notes. I thought MODS might be a possibility, but haven’t been able to import it. Is the Vocabularly URL and the Namespace URI still valid? Are there any known problems with importing this vocabulary?
