What it is

XWiki is an open-source knowledge management and collaboration platform written in Java and licensed under LGPL-2.1. It is described as a generic wiki platform, and it lives in the Productivity & Utilities / Note Taking & Knowledge Management category. The project is part of the XWiki.org software forge, where XWiki Commons, XWiki Rendering, and XWiki Platform are released together and share the same version.

The concrete problem it addresses is the need for a wiki foundation that can support knowledge-management work and applications built on top of it. The README describes runtime services for applications built on top of the platform. That makes it relevant to teams that want a documented, community-supported wiki system, and to developers who want a Java-based platform for wiki-oriented applications. The project provides developer, administrator, and user documentation, plus release notes and a download and installation page.

Who uses it and how

• Teams that need a note-taking and knowledge-management platform can use it as an open-source wiki system.
• Developers can build applications on top of the generic wiki platform and its runtime services.
• Administrators can follow the Administrator Guide and the download and installation instructions when deploying the platform.
• Contributors can report issues through the JIRA issue tracker and follow the development flow and continuous integration setup.
• Community members can discuss the project through the forum, chat, and blog.

Getting started

Follow the Download and Installation instructions linked from the XWiki Platform documentation. The README does not list Docker image names, package managers, or a hosted option.

When to use it — and when not to

Use XWiki when you need an open-source, Java-based, LGPL-2.1 wiki platform with documented developer, administrator, and user guides. Do not rely on GitHub issue or contributor counts for a complete view, because the project uses JIRA and the provided GitHub metadata lists 0 contributors and 218 open issues. The README does not state required database, storage, SMTP, or deployment stack, so self-hosters must read the installation documentation before operating it.
