MediaWiki

MediaWiki (hereinafter, the Software) is a free and open-source wiki software. The Software was originally developed for Wikipedia, but now the Software runs on many websites and has become the dominant software in its category. The Software is written in the PHP programming language and stores the contents into a set of databases.

The software is optimized to efficiently handle large projects, which can have terabytes of content and hundreds of thousands of hits per second. According to MediaWiki, achieving scalability through multiple layers of caching and database replication has been a major concern for developers. The software has more than 900 configuration settings and more than 1,900 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 the Software for collaborative group projects.
