Wikidata (www.wikidata.org,Wikipedia article) is a Wikimedia hosted and maintained project launched in 2012 that aims to create a freeknowledge base about the world that can be read and edited by humans and machines alike. It provides data in all the languages of the Wikimedia projects and allows for the central access to data in a similar vein as Wikimedia Commons does for media files.
It enables central management of interwiki links located in the sidebar, between projects' language versions and across projects covering given subjects, which was previously implemented through individual interwiki links at page bottoms.
