“ Nevertheless, the actual data sets are completely different, both in their vocabulary and their underlying data model. In comparison to other approaches, Wikidata has one of the richest graph formats, where each statement (edge in the graph) can have user-defined annotations (e.g., validity time) and references.
Today, Wikidata is at the core of the Wikimedia projects, a central resource of the world-wide knowledge ecosystem, and an integral part of technologies the world uses every day. Basic statistics are summarized in Table 1.

“ However, Wikidata is much more than a data resource. It is, first and foremost, an international community of volunteers who subscribe to the goal of making free knowledge available to the world. It shares this and other goals with the wider Wikimedia Movement [2] to which Wikidata belongs. Indeed, Wikidata is also a project (and website) of the Wikimedia Foundation, along with sister projects such as Wikipedia and Wikimedia Commons, backed by dedicated staff to create and maintain the infrastructure that enables the work of the community. ”

“ The community decided that images, dates of life, interwikis and authority control data should all come from Wikidata, and it wasn't magicked over the years, it has come from effort, time, coordination and asking favours of outside people (hard work!) . Similarly, where we have research on the author page. overt or hidden, then it is moved to the author talk page; if it duplicates Wikipedia link, then it can just be trimmed. ”
