Page status & SEO link

Since the Mediawiki site containing all the public pages of Cultura italiana is both a standalone site which can be autonomously visited, and a "content management system" (CMS) for a more interactive and "streamlined" experience (as a further example this is the front-end url of this page [1] and this is the back-end url [2]), we have integrated the "back-end" with a way to define some property for each page, and specifically its publishing status, its language, and even some meta-data to be used for SEO ("search engine optimization") purposes.
