Wiki: Pedia

<p>Wikis are websites built for collaborative authoring, allowing numerous contributors to add, edit, and structure content online. Simplicity and openness are central to wikis: anyone can often add or change pages without technical knowledge, and edits are usually logged for review or rollback. Key features - **Collaborative editing:** Multiple people can edit the same pages, occasionally concurrently. - **Edit history:** All edits are stored with timestamps and the author’s name or IP. - **Interlinking:** Links between pages are simple to create, helping build connected content. - **Lightweight markup:** Formatting is usually handled by lightweight markup languages (e.g., WikiText or Markdown). - **Permission settings:** Access controls vary — from fully open editing to permissions for certain users or groups. - **Discussion pages:** Talk or discussion pages let contributors debate edits and organization. Frequent uses - Community-driven knowledge bases (for example, Wikipedia) - Project docs and corporate knowledge repositories - Cooperative writing and shared notes - School and instructional projects Advantages - **Fast collaboration:** Many people can collaborate and iterate quickly on content. - **Openness:** Visibility into edits and discussions shows how decisions were reached. - **Expandable:** Wikis can grow naturally as contributors add new topics. Cons - **Vandalism and false information:** Open contribution can result in deliberate or accidental misinformation. - **Inconsistent quality:** Content quality may vary widely between pages. - **Organizational issues:** Poor coordination or governance can cause content fragmentation and disputes.
