MediaWiki is a free and open-source wiki application. Originally developed by Magnus Manske and improved by Lee Daniel Crocker, it runs on many websites, including Wikipedia, Wiktionary and Wikimedia Commons.[4][5] It is written in the PHP programming language and stores the contents into a database. Like WordPress, which is based on a similar licensing & architecture, it has become the dominant software in its category.
The first version of the software was deployed to serve the needs of the Wikipedia encyclopedia in 2002.[6] Wikipedia and other Wikimedia projects continue to define a large part of the requirement set for MediaWiki.[7] The software is optimized to efficiently handle large projects, which can have terabytes of content and hundreds of thousands of hits per second.[7][8] Because Wikipedia is one of the world's largest websites, achieving scalability through multiple layers of caching and database replication has been a major concern for developers.
The software has more than 800 configuration settings[9] and more than 2,000 extensions available for enabling various features to be added or changed.[10] On Wikipedia alone, more than 1000 automated and semi-automated bots and other tools have been developed to assist in editing.[11]
It has also been deployed by some companies as an internal knowledge management system,[12] and some educators have assigned students to use MediaWiki for collaborative group projects.[13]
