Suppose the worldbuilding itself is an artistic creative effort, rather than just a means to write a good novel. People have asked about software for organizing information before. But I'm raising the question where the method in question is the publication mechanism as well.
There are indeed wiki sites for various popular franchises including Star Trek and Harry Potter. I'm thinking what I want would be classified as a "wiki", but with specific features.
It starts off with the author making the content. Others would not edit that, but I want people to be able to attach comments to specific points, not just to the bottom of the page as a whole. Think about reviewing tools in documents.
Eventually, when it (or some area) is finished, it can be released under a creative commons type licence and open those pages to editing by anyone. I expect it to have version history.
It should allow for formatting the content with bold and italic etc. but not limited to only that: a created style might need a custom font or color for example.
Any wiki allows for embedding pictures in some way, but what about navigating map content with pan and zoom? How do you post and edit such maps? Vector content in general, so CAD drawings can be exported to a vector format for posting, not huge or low-res bitmaps.
