XWiki

XWiki is an open-source wiki software written in Java, designed for collaboration, knowledge management, and enterprise content organization. It is used by individuals, teams, and organizations to create, structure, and share information in a wiki-driven environment.

Core features include a page-centric data model that supports structured data through objects and properties, page versioning and history, fine-grained access control, and full-text search. The platform provides a WYSIWYG editor, inline editing, and a macros system for extending pages. It supports templating and skins to customize the look and feel, and includes a built-in workflow and activity stream for collaboration. An extension framework and a large ecosystem of apps (extensions) let users add features such as document management, diagrams, calendars, and project dashboards. Data can be organized with namespaces, tags, and relations, enabling both wiki-style content and structured data use.

Technical overview: XWiki runs on Java servlet containers (for example Tomcat or Jetty) and stores content in relational databases such as MySQL, PostgreSQL, Oracle, or MariaDB. It exposes RESTful APIs, supports WebDAV access, and offers a scripting layer (Velocity and Groovy) for customization. Security features include access control lists, groups, and integration with LDAP or single sign-on systems.

Deployment and usage: XWiki is commonly deployed for intranets, knowledge bases, product documentation, and collaborative portals. It supports multilingual content, backup and restore, and scalable installations for organizations of different sizes. The project is open-source, maintained by a community of contributors with commercial support available from sponsors and partners.
