It says in the page's infobox that there's a permission titled (smw-curator) However the only permission that I'm aware of that comes with this extension is the (smw-admin) permission. Does the (smw-curator) permission actually exist and is unused? Or is the information regarding the (smw-curator) permission incorrect, and there's only a usergroup under the name 'Smwcurator'?

Yes, there is. See this docu. There is even an "smweditor" group that came in with this pull. Still undocumented on the wiki.
I'm not seeing the (smw-curator) permission on either of the pages you linked.
Ah, I mixed it with the user group. I am sorry for the confusion. Indeed there is no smw-curator permission. I just updated the docu here.
