I was trying to follow the nofollow discussion (http://meta.wikimedia.org/wiki/Nofollow#Current_use_on_Wikimedia_projects). I see it hinges on "external links", and my question about it would be concerning when an interwiki link to a sister project is deemed "external". For context, I use many links to Wikisource pages I have created as references, and was wondering whether the [[:s: ***]] construction is read as an "external" link.
