How to get automatic backlinks when linking files in in org-mode?

Question

Is it possible to automatically create backlinks to org-mode links? When a link to file B is added to file A, then also a link to file A is added to file B (i.e. the links are symmetrical - going both ways).

A concrete example:

I have two files a.org and b.org.

Inside a.org in heading Links I insert an org-link (with a new function org-link-with-backlink) to the file b.org.

So file a.org looks like this:

* Links
  [[~/org/b.org][b]]

* Heading 1
  lorem ipsum....

I'd like this to happen automatically:

1. the file b.org is opened (if not open already)

2. and inside its Links heading a link to a.org is created.

If Links doesn't exist yet, create it by prepending the file and add the link.

If b.org already has a link to a.org in its Links heading then do nothing.

So that b.org looks like this after the operation:

* Links
  [[~/org/a.org][a]]

* Heading X
  foo bar....

If now I inside file c.org add also a link to b.org, then b.org now looks like this:

* Links
  [[~/org/a.org][a]]
  [[~/org/c.org][c]]

* Heading X
  foo bar....

I think some sort of advice around org-link should accomplish this, but unfortunately this is beyond my elisp skills...

Thank you very much!

PS [optional]: I intend to use it in conjunction with org-wiki, to the solution could use the wiki style links as an alternative.

Answer 1

I just saw this new emacs package org-super-links that allows backlinks creation.

Usage example:

* Section A
  :PROPERTIES:
  :ID:       6a63d1d9-d361-4586-9315-6f7cb98ab2ef
  :END:
  :BACKLINKS:
  [2020-04-12 Sun 11:42] <- [[id:0c924010-a1cb-4f01-b4af-05a33ce588fe][Section B]]
  :END:

* Section B
  :PROPERTIES:
  :ID:       0c924010-a1cb-4f01-b4af-05a33ce588fe
  :END:

  I'm section B and this [[id:6a63d1d9-d361-4586-9315-6f7cb98ab2ef][Section A]] is a 
  link to section A
