I've been working on the backend for my personal website for a bit now, and while having a blog is nice for keeping a running list of thoughts and articles, for me and my way of thinking, having a sort of interlinked knowledge base closely coupled with articles and thoughts makes a bit more sense. ( Think something closer to Gwern's site (though it is based on Hakyll) or Chris' Space (https://utcc.utoronto.ca/~cks/space/FrontPage). )

Is this a category of sofware that exists, and if so, what are the major players in the space ?
