Wiki: Pedia

<p>A wiki is a web platform that enables multiple users to collaboratively create, edit, and arrange content through a browser. 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. Main features - **Collaborative editing:** Numerous contributors can work on pages, sometimes simultaneously. - **Edit history:** Every modification is recorded with a timestamp and the editor’s identity or IP address. - **Interlinking:** Creating links among pages is straightforward, which helps interconnect 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. Typical uses - Community knowledge bases such as Wikipedia - Internal documentation and company knowledge bases - Cooperative writing and shared notes - Classroom and educational projects Advantages - **Fast collaboration:** Contributors can rapidly create and improve content. - **Openness:** Transparency through revision histories and discussions. - **Expandable:** They scale organically as users add more pages and topics. 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:** Poor coordination or governance can cause content fragmentation and disputes.
