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. Key features - **Collaborative editing:** Multiple people can edit the same pages, occasionally concurrently. - **Edit history:** Every modification is recorded with a timestamp and the editor’s identity or IP address. - **Interlinking:** Links between pages are simple to create, helping build connected content. - **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:** Separate talk pages allow contributors to discuss edits and structure. Common uses - Community knowledge bases such as Wikipedia - Project documentation and internal company knowledge repositories - Collaborative writing and shared note-taking - Classroom and educational projects Benefits - **Fast collaboration:** Many people can collaborate and iterate quickly on content. - **Openness:** Transparency through revision histories and discussions. - **Expandable:** They scale organically as users add more pages and topics. Limitations - **Vandalism and false information:** Open contribution can result in deliberate or accidental misinformation. - **Inconsistent quality:** Entries may vary in accuracy, style, and completeness. - **Organizational issues:** Without clear governance, content may become fragmented or disputed. Notable example - **Wikipedia** — the best-known wiki, run by the Wikimedia Foundation and built by volunteer contributors worldwide.</p>
