Wiki: Pedia

<p>A wiki is a web platform that enables multiple users to collaboratively create, edit, and arrange content through a browser. Wikis prioritize ease of use and openness: pages can be added or changed without technical expertise, and most track every edit so changes can be reviewed or undone. Main features - **Collaborative editing:** Several contributors can edit pages, sometimes at the same time. - **Edit history:** Every modification is recorded with a timestamp and the editor’s identity or IP address. - **Interlinking:** It’s easy to create links between pages, forming an interconnected knowledge base. - **Lightweight markup:** Pages are typically formatted with lightweight markup like WikiText or Markdown. - **Permission settings:** Some wikis are open to anyone; others limit edits to registered users or specific groups. - **Discussion pages:** Talk or discussion pages let contributors debate edits and organization. Frequent uses - Community knowledge bases such as Wikipedia - Internal documentation and company knowledge bases - Cooperative writing and shared notes - Classroom and educational projects Pros - **Fast collaboration:** Many people can collaborate and iterate quickly on content. - **Openness:** Visibility into edits and discussions shows how decisions were reached. - **Expandable:** Wikis expand easily as contributors add and organize content. Drawbacks - **Vandalism and false information:** Open contribution can result in deliberate or accidental misinformation. - **Inconsistent quality:** Content quality may vary widely between pages. - **Organizational issues:** Without clear governance, content may become fragmented or disputed.
