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. Key features - **Collaborative editing:** Several contributors can edit pages, sometimes at the same time. - **Edit history:** Each change is logged with a time and the editor’s name or IP. - **Interlinking:** It’s easy to create links between pages, forming an interconnected knowledge base. - **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. Frequent uses - Community-driven knowledge bases (for example, Wikipedia) - Internal documentation and company knowledge bases - Collaborative writing and shared note-taking - School and instructional projects Advantages - **Fast collaboration:** Contributors can rapidly create and improve content. - **Openness:** Transparency through revision histories and discussions. - **Expandable:** Wikis can grow naturally as contributors add new topics. Limitations - **Vandalism and false information:** Open editing may allow intentional or accidental inaccuracies. - **Inconsistent quality:** Entries may vary in accuracy, style, and completeness. - **Organizational issues:** Poor coordination or governance can cause content fragmentation and disputes. Example - **Wikipedia** — the largest example, maintained by the Wikimedia Foundation and contributed to by volunteers worldwide.</p>
