Mediawiki is a free open source wiki package originally used on Wikipedia. It is also used as CMS by non-profit Wikimedia Foundation projects, wikis and several other projects. It is written as PHP application and is server based. Its documentation is in English language but some contents have been translated in other languages also.
Uploading of graphics or sound files is possible. These files can be listed on ‘Recent changes’ and can also be logged on Special log. Mathematical formulae can also be operated using Latex syntax. Simple syntax is also inbuilt for image alignment and image caption. Image Magick and libgd in software helps in automatic resizing of images.
Wiki Hiero to produce Egyptian hieroglyphs and Easy Time Line for time charts can also be installed separately with minor effects. It is possible to edit an individual section of article instead of loading complete article by Section editing option. Edit toolbar is in Java script and works in Mozilla and IE like browsers. Edit Summary, Double click editing, Edit preview etc are other important options.
Multiple categories can be given to any page and it permits classification and hierarchical browsing of contents of the page. Editing syntax based on UseMod, Word Extension linking, support for subpages, special keywords for including dynamic data in content and transclusion of pages according to page name are very useful features.
Talk Pages, Namespace to permit content separation, automatic signature just with three tides and message notification along with support for email users are quite useful in publication projects.
Mediawiki merges changes immediately, along with manual merger option. Signed in users can mark edits as minors and can hide them from ‘Recent Changes”. Parenthetical hiding is very useful for Copyright. The software with Multilanguage support is recommended for project management.
