The Semantic Forms, Semantic Drilldown, and Semantic Search extensions have been made available on this wiki. The input form for individuals became fairly workable early in 2010 and after several bad spells with software changes it became just a little better in December 2012; searching has been available for longer. Check Forum:SMW and other forums or post a new query on the help desk about progress and use; if no response within 48 hours, try User:Thurstan or User:rtol (whichever one has been most active recently).

Wikia made it available but stated that "Wikia's Community Team cannot provide support on using it". By late 2012 Wikia had even deleted its "Help" page on the subject. We are on our own except for outside help (e.g. the official website) and occasionally other Wikia users who have some insight into how it works and why aspects of it do not always work.

Until redirected in September 2010, the help page on Wikia Help said the following:


Template:Available on request

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.

es:Ayuda:Semantic MediaWiki

Extensions are features and add-ons developed for Help: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 wikia or overriding a built-in MediaWiki feature for customization purposes.

How to request an extension

First, verify that the extension you are looking for does not exist already on your wikia. You can check this by going to Special:Version and looking under the "installed extensions" section or checking the extension's parser function or tag against the "tags" and "hooks" section at the bottom of that page. Wikia already has a significant number of extensions enabled by default.

Many other extensions are already in our codebase and can be enabled upon request. You can check what extensions Wikia offers later in this page. Some basic content tools, such Maps and Help:Variables, are automatically enabled by staff. Other complex extensions, such as DPL, usually have a staff member ask a few questions to ensure that the extension you are asking for is in fact the ideal solution. Other extensions, where wikia configuration may be dramatically changed (such as Abuse Filter, will be enabled at staff discretion depending on the context of the request.

If Wikia does not offer a particular extension, you may request our engineering staff investigate installing it by using Special:Contact and linking to the MediaWiki extension page along with some rationale as to why it's needed. Please be aware that our engineering staff may take a few months to review the extension and that most extensions will be rejected. This is mainly due to the amount of rewriting an extension would face to live on the Wikia codebase servers. As such, it's always good to ask yourself when looking an extension on MediaWiki.org if the extension is up to date, is well-maintained, and allows for a caching layer. If the answer to any of these questions is no, chances are we will not be able to install the extension.
