Quite some years ago I created a Python FUSE filesystem[1] to to interact with dokuwiki (a wiki system).

It's built on hde llfuse[2]. But that required implementing a bunch of low level APIs that were not really related to dokuwiki. So I created easyfuse[3][4] as a wrapper, which implemented the things that were unrelated the dokuwiki implementation. If you're interested it in building a FUSE system it might be worth looking at.
