MediaWiki is a Web-based collaborative editing environment
MediaWiki is a Web-based collaborative editing environment. MediaWiki was originally built for the online encyclopedia project Wikipedia, it's geared to support a large number of users and pages.
Here are some key features of "MediaWiki":
Side bar: A bar on the left or right of the screen with short-cuts
Skins: Different ways to present the site, can be expanded using PHPTal templates.
o Monobook, a modern skin with accesskeys and tooltips
User styles: Users can adapt the look and feel of the site through custom CSS on their user pages.
"Stub" threshold: Users can see links to articles below a certain size rendered in a different color
Printable versions of articles can be generated
Auto-number headings in an article (optional)
Generate a table of contents for long articles (optional)
Automagically turn ISBN numbers into links to an editable list of booksellers
XHTML-compatible output (or darn close to it), tidy integration
File upload feature allows to upload graphics or sound files, see special:Upload. Uploaded files are listed on Recent Changes and they are also logged on log:Uploads.
Mathematical formulas using LaTeX syntax: see texvc
Automatic resizing of images using ImageMagick or libgd, simple syntax for image captions and image alignment
WikiHiero for Egyptian hieroglyphs
EasyTimeline for time charts
Watchlist Every page has a link "Watch this article for me". Use special:Watchlist to track changes on the articles you declared an interest in; watched articles are also bolded in the Recent changes list .
User contributions in the sidebar of each user page list all articles the user has worked on, according to the database.
Extended recent changes with dynamic collapsing of edits to the same article and quick links to diff the edit, show the article history, show the user page, show the user talk page, or block the user (for sysops)
"Related changes": View a filtered version of Recent Changes to the pages linked from the current page.
Side-by-side diffs - the diffs are shown side-by-side, and changed portions of lines are highlighted, making it much easier to see what's what. Additionally, a diff is shown during an edit conflict so you can see exactly what you need to reintegrate.
Real names. Users can (optionally) specify a "real name" they want to use for author credits.
On-page credits. Administrators can enable an on-page paragraph giving credit to editors who've worked on a page.
Editing syntax based on UseMod, with support for mixing wiki-syntax and HTML. Only free links are supported for linking, not CamelCase (deliberate design decision).
Namespaces allow content separation (to address the namespace, use the [[Namespace:Page title]] syntax).
- Discussion (Talk:) pages are separate from article pages, "meta" project pages can be separated from content pages, image pages are used for image descriptions.
- MediaWiki: namespace contains all user interface texts, so that they can be edited like any other wiki page
- Template: namespace for custom messages. Templates may contain string variables which are replaced with certain values passed to the template from the calling page.
Transclusion of arbitrary pages in any namespace.
Word-extension linking: If you include a link of the form [[war]]s, or [[war]]time, the system will automatically display it as if you had typed [[war|wars]] or [[war|wartime]], respectively, saving some typing.
Parenthetical hiding If you include a link of the form [[kernel (mathematics)|]], the parenthetical portion will be hidden in the link: kernel. This is useful for disambiguating different meanings of a word without making linking too difficult or cluttering up the text of articles. This also works with cropping out namespaces when you want a cleaner-looking link: [[Wikipedia:copyrights|]] becomes copyrights
Link to individual sections of an article, e.g. MediaWiki roadmap#Version 1.4 (these links may become invalid if sections are retitled or removed)
Support for subpages (link to "Foo/Bar" from "Foo" by just typing "/Bar", "Foo/Bar" contains a backlink to "Foo"), these can be enabled or disabled by namespace (e.g., Wikipedia currently supports subpages on discussion pages, to make archiving easy, and on user pages, to give users space for personal pages)
Special keywords for inserting dynamic data such as the name of the current page, the current date, the number of articles, etc.
Multiple Categories can be assigned to any page, including categories itself eventually creating a hierarchy of categories. Category pages automatically list all pages assigned to them including sub-categories. Categories allow classification and hierarchical browsing of the content.
Section editing. Users can enable an option that allows them to edit individual sections of an article (separated by headlines) instead of loading the entire article.
Edit summary which is shown in "Recent changes". Will be prefilled with section title when section editing.
Double click editing: Users can enable an option that allows them to edit articles by double clicking them.
Edit preview (can be shown before or after edit box)
Handle edit conflicts (page being saved by a user while still being edited by another one, then saved again). MediaWiki will merge changes automatically if possible and otherwise require the user to do a manual merge.
Mark edits as minor; users can decide to hide such edits from the Recent Changes list. Only signed in users can mark edits as minor.
Talk pages: Each user (including every anonymous user) and every article has an associated page where messages can be left. These are separate namespaces (see above), "Talk:" and "User talk:".
Message notification (user gets a "You have new messages" notice if someone else has edited their user discussion page); this also works for anonymous users
Automatic signature: Just type three tildes (~) when you edit, and on saving the page, it will be replaced with your user name and a link to your user page. If you use four tildes, the current date will be added as well. Mainly intended for Talk pages.
Support for emailing users through the wiki (email address not shown to the user)
Translated into many languages (see en:Wikipedia:Multilingual coordination for details)
Interlanguage links: handy method for linking articles between wikis in different languages (each language requires its own database)
Database-driven (MySQL, no other databases currently supported)
Smart caching: rendered pages are (optionally) saved as static HTML files and served as such unless modified; support for Squid proxies
Cookie-based account and login system, but anonymous users can also edit pages
All revisions of an article are stored (optionally compressed)
RSS syndication available for many special pages, such as Special:Newpages.
Different rights for anonymous users, signed in users, sysops, bureaucrats and developers.
Signed in users can:
- move and rename pages
- upload files
- have and use a watchlist
- mark edits as minor edits (eg. typo correction)
- protect pages from editing
- delete and undelete pages
- edit protected pages
- ban users by IP address
- ban users by username, if this option is enabled
- run SQL queries on the database, if this option is enabled
- create sysops
Developers (admins) can:
- lock the database
- run various maintenance tasks
Other permission schemes (e.g. only signed in users can edit pages) can be configured
Full text search
"Go" button allows direct viewing of a specified article's contents (tries near match if no exact hit)
"What links here": View pages that link to the current page (backlinks)
Special report pages:
- New pages: List of newly created articles
