Are there any Public Knowledge Databases?

Question

I have seen some folks selling their PKM databases on gumroad. Usually using Roam Research. I think its a wonderful way to learn about some topic or discover new subjects. Think of it as an ever growing online encyclopedia. Imagine crowd sourced databases about biotech, defi & other topics. Are there any existing solutions?

I have slowly planned out a project similar to this. I'm interested in having a tool which allows for shared collaboration on various lengths of content (e.g. lists, guides, etc.). While I don't think it will lead anywhere (there are plenty of great note-taking platforms already) it will be a fun exercise.
