"A wiki is a page or collection of Web pages designed to enable anyone who accesses it to contribute or modify content, using a simplified markup language. Wikis are often used to create collaborative websites and to power community websites. The collaborative encyclopedia Wikipedia is one of the best-known wikis. Wikis are used in business to provide intranets and Knowledge Management systems" 1.
Originally, the word "wiki" is hawaiian and means "fast" or "quick" 2. According to Ward Cunningham, the developer of the first wiki software called WikiWikiWeb, the name was chosen "as an alliterative substitute for quick and thereby avoided naming this stuff quick-web" 3.
As mentioned above, the idea behind wikis is that anybody can create and edit content of a wiki page, using a simplified markup language.
A markup language is a language that combines text with additional anotations that have an impact of the presentation of the text itself once it is displayed. An example for markup language is HTML (Hypertext Markup Language) that is the basis for the majority of internet websites. In conjunction with wikis, the markup language is reduced to a few simple annotations that easily allow any user to format a wiki page. The markup language used on this Atomikos site is called TML which stands for Topic Markup Language. For detailed information, see ShortHand.
According to its founder, the basic principles of a wiki are 4:
To avoid malicious intents of manipulation of contents, a wiki normally comes with a revision control system that backs up any changes that are done to a topic and that can be recovered at any time, if necessary.
The first wiki, WikiWikiWeb, was dated online on March 25, 1995. Soon clones were published, probably the first by Patrick Mueller written in REXX for OS/2. Cunningham himself wrote a version of wiki that could host its own source code called WikiBase.
Another one was CvWiki, developed by Peter Merel in 1997. It was the first wiki clone that had a functioning transclusion and backlinks. Besides it was fully integrated with a revision control system that permited basically unlimited tracking of changes.
Today there is a variety of wikis, one of them being the wiki you are presently looking at.
Foswiki is the latest in a line of Perl wiki implementations that started with the JosWiki clone in the late 1990's. For a full history of Foswiki, visit the Foswiki website.
