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:** Wikis may allow public editing or restrict changes to registered or authorized users. - **Discussion pages:** Dedicated discussion pages enable contributors to coordinate and discuss content. Common 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:** Contributors can rapidly create and improve content. - **Openness:** Edit histories and talk pages reveal how content decisions were made. - **Expandable:** Wikis expand easily as contributors add and organize content. 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:** Without clear governance, content may become fragmented or disputed.
