wikijärjestelmät

Wikijärjestelmät, commonly referred to as wiki systems, are collaborative web-based applications that allow users to create, edit, and link web pages together. The defining characteristic of a wiki is its open editing model, which enables virtually anyone with access to the system to contribute and modify content. This decentralized approach to content creation distinguishes wikis from traditional websites where content is typically managed by a limited number of administrators.

The underlying technology of a wiki system relies on a database to store page content and a web server to render the pages. The editing interface is usually simple, often employing a markup language or a WYSIWYG (What You See Is What You Get) editor, making it accessible to users without advanced technical skills. Version control is a crucial feature, as it allows users to track changes made to a page, revert to previous versions, and monitor contributions.

Wikis are widely used for a variety of purposes, including knowledge management within organizations, collaborative project documentation, community-driven encyclopedias like Wikipedia, and personal note-taking. Their strength lies in their ability to foster rapid knowledge sharing and collective intelligence. The ease of contribution and the transparent revision history promote a dynamic and evolving information base. Despite their open nature, many wiki systems incorporate moderation tools and user permissions to manage content quality and prevent abuse.
