Extend Dublin Core template support to include DC terms
Based on a request from the community, 2018-12-19 - see: https://github.com/artefactual/atom/issues/814
There are many more elements we could crosswalk to ISAD with DC terms support. We could also likely import more metadata from Archivematica DIP uploads this way. Would require changes not only to DC edit and view pages (and relevant crosswalking to related fields in other templates), but also to DC XML import/export.
