Wiki: Pedia

<p>Wikis are websites built for collaborative authoring, allowing numerous contributors to add, edit, and structure content online. 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. Common features - **Collaborative editing:** Multiple people can edit the same pages, occasionally concurrently. - **Edit history:** Each change is logged with a time and the editor’s name or IP. - **Interlinking:** Creating links among pages is straightforward, which helps interconnect content. - **Lightweight markup:** Formatting is usually handled by lightweight markup languages (e.g., 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 - Crowd-sourced knowledge resources (e.g., Wikipedia) - Project documentation and internal company knowledge repositories - Collaborative writing and shared note-taking - Classroom and educational projects Advantages - **Fast collaboration:** Many people can collaborate and iterate quickly on content. - **Openness:** Transparency through revision histories and discussions. - **Expandable:** Wikis expand easily as contributors add and organize content. Limitations - **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.
