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. Main 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:** 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:** 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. Typical uses - Community-driven knowledge bases (for example, Wikipedia) - Project docs and corporate knowledge repositories - Cooperative writing and shared notes - Classroom and educational projects Advantages - **Fast collaboration:** Many people can collaborate and iterate quickly on content. - **Openness:** Edit histories and talk pages reveal how content decisions were made. - **Expandable:** Wikis expand easily as contributors add and organize content. Limitations - **Vandalism and false information:** Public editing can lead to vandalism or incorrect information. - **Inconsistent quality:** Content quality may vary widely between pages. - **Organizational issues:** Poor coordination or governance can cause content fragmentation and disputes.
