Help:Extensions

Extensions are features and add-ons developed for MediaWiki, the software platform that Wikia runs on. They are designed by third-party developers (that is to say, not Wikia or MediaWiki staff) for the purpose of either expanding the function of a wiki or overriding a built-in MediaWiki feature for customization purposes.

See Category:Extensions for help pages on Wikia Help. Note this article may not be completely up to date.

Semantic Extensions
Wikia does offer a family of extensions called "Semantic" extensions.

Semantic MediaWiki is a powerful extension that helps users to search, organise, tag, browse, evaluate, and share a wiki's content. While traditional wikis contain only text which computers can neither understand nor evaluate, SMW adds semantic annotations that allow a wiki to function as a collaborative database.

Wikia can enable Semantic MediaWiki (and related extensions Semantic Forms and Semantic Drilldown) on request for wikis which have users on hand who know how to use it, or are willing to learn and provide support for others.

The extension is very flexible, which means that it has complicated aspects which take time to master. Wikia's Community Team cannot provide support on using it, but the Semantic-MediaWiki.org wiki provides a manual, mailing list and chatroom for finding help. See also help on Semantic Search.
