First two paragraphs of article on MediaWiki site:
"Page Forms (known until November 2016 as Semantic Forms) is an extension to MediaWiki that allows users to add, edit and query data using forms. It was originally created as an offshoot of the Semantic MediaWiki extension, to be able to edit templates that store their parameters via SMW, which is why it was originally called "Semantic Forms". However, it can now also work with the alternative Cargo extension, or with neither extension installed.
"Very simply, Page Forms allows you to have forms for creating and editing pages on your wiki, as well as for querying data, all without any programming. Forms can be created and edited not just by administrators, but by users themselves."
By 8 May 2018, FANDOM/Wikia sites still had Semantic Forms version 3.7. and Semantic Drilldown (Version 2.0.1) and Semantic MediaWiki (Version 2.4.6)
