Emacs Freex
*Emacs Freex looks like a very interesting (but perhaps no longer maintained?) project - described as a "personal wiki on steroids".
Looks like it had Transclusion, autolinking. Worked with another old project called Muse for publishing.
Looks like it worked in a fairly similar way to org-roam - a DB layer over text files.
