A wiki (/wɪkiː/ listen ) is a website where an unspecified number of people can directly modify the content and structure through collaboration. In addition, in a general wiki, text is written using a simplified markup language (wiki markup). , sometimes edited with the help of a rich text editor. Wikis are used for various purposes such as knowledge management and records. It is also used for community websites and intranets within organizations. However, there are also wikis that are mainly used for personal use, which are called personal wikis.
Ward Cunningham, creator of the first wiki software, WikiWikiWeb, described wikis as "the simplest online database that works." "Wiki" is derived from the Hawaiian word "wiki" (pronounced ˈwiti or ˈviti), which means "quick".
In the book The Wiki Way: Quick Collaboration on the Web, written by Ward Cunningham with Borough, the most essential concept of a wiki is as follows:
Anyone who visits the site can edit or create new articles within the wiki website. All you need is a basic web browser for this, and no additional extensions are required.
A wiki can create meaningful links between topics by simply linking different documents, and even show whether the document exists or not.
The wiki is not a well-designed site for casual visitors. However, it continuously changes the landscape of the website, allowing visitors to participate in the ongoing process of change and collaboration. Wikis enable communities to write documents together using a simple markup language and a web browser. One article on the wiki website is called a "wiki article", and the entire article linked together by hyperlinks is called a "wiki". A wiki is essentially a database for creating, browsing, and retrieving information. Wikis enable non-linear, evolving, tangled documentation, discussion, and interaction. A defining characteristic of wiki technology is the ability to create and edit documents simply. There is generally no process of approval or review before amendments are reflected. Most wikis do not require user registration and are open to the public. Many editors create it in real time, and it is immediately distributed online. However, this can lead to abuse of the system, but mainly has more advantages. Private wikis often require user authentication to edit or read documents.
Editing wiki pages
In general, wiki pages are written in a simple markup language called wiki markup. For example, a line beginning with an asterisk (*) is used to display a list. The syntax of wiki markup is different for each wiki software, and some even allow you to use HTML directly.
More and more wikis support users to edit WYSIWYG. Since WYSIWYG Edit doesn't provide all the features of wiki markup, these sites also provide a way for editors to directly edit wiki pages.
Most wikis keep a history of changes to wiki pages. Editors can easily revert the document to the content of the previous edition, which is necessary because of user error or intentional damage. Many wiki software, including MediaWiki, allows you to leave a "edit summary" when you edit a document. This editorial summary does not remain in the body of the document, but in the history of the document.
