> NoZebra120vClip@: EDIT: Headline says "Wikipedia" but screenshots are allegedly "Wikidata" which is really different.
OP: We use "Wikipedia" here because that's what most audience might recognize. In technical specifics, the site is Wikidata.org which is a sister project of Wikipedia, also supported by Wikimedia Foundation and share the same spirit. The Wikipedia is powered by software called MediaWiki, and Wikidata uses an extension of MediaWiki called Wikibase. It has its whole ecosystem and terminologies like all other open source movement.
