MediaWiki


MediaWiki is a free web-based wiki software application. Developed by the Wikimedia Foundation and others, it is used to run all of the Foundation’s projects, including Wikipedia, Wiktionary and Wikinews. Numerous other wikis around the world also use it to power their websites. It is written in the PHP programming language and uses a backend database.

The software was initially deployed to meet the needs of Wikipedia and is optimized to efficiently handle large projects, which can have terabytes of content and hundreds of thousands of hits per second. Wikipedia is one of the world’s largest websites, and MediaWiki provides the needed scalability through multiple layers of caching and database replication.

The software is highly customizable, with more than 700 configuration settings and more than 1,800 extensions available for enabling various features to be added or changed. On Wikipedia alone, more than 1000 automated and semi-automated bots and other tools have been developed to assist in editing.

It has also been deployed by some companies as an internal knowledge management system, and some educators have assigned students to use MediaWiki for collaborative group projects.
