We have (at the moment) two content models, and sub-models within those. (We may decide to break them out into dedicated content types.) We have:
- Hubs (main hubs), i.e. WikiProjects, which include an introduction, announcements, member list, and sections based on transcluded subpages of arbitrary content models, as well as an auto-generated table of contents based on the transcluded sections.
- Hub subpages, which are basically wikitext pages but with additional metadata that allows for things like automatically loading the navigation icons
- Structured lists, typically of articles, that have built-in sorting functions and the ability to selectively transclude them (T129271), consistent with WPX design principles.
