It is described in (info "(elisp)Magic File Names")

In short: you add an entry to `file-name-handler-alist', let's say
("\\`/wiki:" . my-wiki-file-name-handler). `my-wiki-file-name-handler'
must be a function, which implements the primitive file name functions
listed in the manual, or calls another implementation of that function,
like the one from Tramp.

If it is of wider interest, we could also think about a more tight
integration into Tramp.

That's possible. Maybe you study the Tramp code. tramp-imap.el has been
added recently by Ted Zlatanov. tramp-smb.el has a similar history (it
was my first contribution to Tramp). Both provide handling for special
Tramp methods.
