Interesting Extensions

What extensions should I use on my wiki?

1. We are the developers of the Html2Wiki extension which lets you import HTML web pages into your wiki.
2. Extension:QuickLink should be updated. It provides an easy way to link to other articles while editing.
3. Extension:TitleKey (git ) is written by Brion Vibber and offers interesting capability that is used on some/all? MW sites. Also, since it interacts with the MW internal search, it's a good example of how to create an extension that hooks into the search functionality. The TitleKey extension provides a case-insensitive title prefix search. It uses a separate table for the keys, so if it works cleanly it can be deployed without an expensive rebuild of core tables, and dumped when Wikimedia gets a nicer backend through Extension:LuceneSearch (pre 1.13) or Extension:MWSearch (1.13+). Note that MediaWiki has stopped using LuceneSearch and is now using mw:Extension:CirrusSearch which interfaces to wp:Elasticsearch (which is based on Lucene) on the backend. For the average site administrator, the benefit of this extension is that it allows search suggestions (e.g. from Opensearch API) to be case-insensitive.
4. Uncyclopedia uses a lot of interesting extensions http://en.uncyclopedia.co/wiki/Special:Version
5. There are about 164 MediaWiki extensions used by WMF projects These extensions as a group have had 131,043 commits made by 537 contributors representing 1,155,573 lines of code over the decade from April 2004 - November 2014
6. Then there are MediaWiki extensions hosted in the Wikimedia Foundation servers but not deployed in official Wikimedia projects. These extensions have had 84,409 commits made by 461 contributors representing 891,451 lines of code. The fact that these extensions are hosted on WMF servers does not imply endorsement. Rather, it shows that the developers are at least savvy enough to use the git hosting system available to extension developers and put in the effort to publish their projects.

Notes on Installed Extensions

Add Images

An extension found at wikia (also called WikiaMiniUpload?), it allows you to add images from Flickr, the web, and those already uploaded to your local wiki. It also adds a new button to the editor (a feature lacking in the standard editor). Video and instructions at http://help.wikia.com/wiki/Help:Add_Images

DataTable2

http://www.mediawiki.org/wiki/Extension:DataTable2 essentially does the converse of Semantic Media Wiki. Instead of storing data on multiple pages, which can then be queried and displayed, this extension allows for saving data in a single (or multiple) page and reusing that data on multiple pages.

Interwiki

The Interwiki Extension has been added which makes it easy to manipulate the interwiki table. http://mediawiki.org/wiki/Extension:SpecialInterwiki But what is the Interwiki table you say? The Interwiki table sets up internal namespaces making it convenient for authors to create links to other wikis. For example, you can link to a Wikipedia article with the following syntax: [[WikiPedia:Thomas_Jefferson]] .

There is a long list of wikis and sites already included in the Interwiki table.

Semantic Bundle

A great way to get all the goodness of SMW in an easy way.

VisualEditor

git clone https://gerrit.wikimedia.org/r/p/mediawiki/extensions/VisualEditor.git

SyntaxHighlight_GeSHi

A must-have for any wiki that has code samples in it.

HyperText Markup Language = structured text that uses logical links (hyperlinks) between nodes containing text.

Application Programming Interface

WikiMedia Foundation = the organization which runs various projects including Wikipedia.org
