@ubermichael I've kept this as a single ticket and assigned this to myself for now since, as far as I know:

• The change of "Contents" to "Poems" will just be a text change (i.e. the path will still be mvm/contents/1 and not mvm/poem/1)
• The addition of descriptions will just be done on the back-end and won't editable from the interface.
