django-wiki is a full-featured wiki system built as a reusable Django application. It provides hierarchical wiki pages with URL slug paths, revision control, attachments, images, notifications, and granular permissions. The architecture is modular, with a plugin system that allows extensions like macros, image galleries, and notification digests. Content is authored in Markdown with custom extensions for wiki links, tables of contents, and code highlighting. The system integrates with Django's authentication, sites framework, and admin interface. It is designed for production use with caching, spam protection, and i18n support. The codebase is well-structured with clear separation of concerns, though it carries some technical debt from vendored frontend assets and deprecated patterns.
