I was experimenting with idea of backlinks since 1 year, 3 months and
14 days. For me personally, it is not easy, but I managed to record
backlinks. Let us say I am writing email, insert link there, the link
that I inserted it in the email will know that I inserted it in the
email, and its file name, but it will not know the ID of the person to
which email belonged. Maybe I could handle the best mail software for
Emacs (mutt) to send some information about currently replied email
address to connect to it.

Otherwise if I use some kind of interpolated links like:
⟦ (link 123 "Name") ⟧
then each interpolation could eventually make the link remember where
it was inserted.

My note buffers have different local variables: rcd-current-table
refers to table in database, such as "hyobjects" (elementary objects
in terms of Doug Engelbart), and there is rcd-current-table-id such as
1, which refers to the row #1 in table hyobjects. Inserting link into
the buffer like that makes the link notify that it was inserted
there. But how it is going to remember when the link disappears?

The only way to go for backlinks to be remembered at all times is to
treat them as elementary objects, see:

https://www.dougengelbart.org/content/view/116/#7j

Elementary Objects:
https://www.dougengelbart.org/content/view/110/460/#2a1a

Imagine elementary objects under a list named "Document":

1 Introduction paragraph
2 link #1
3 link #2
4 Image
5 Body of document

Now imagine document being joined together, something like:

Introduction paragraph (link #1) Body of document

In that way when all elementary parts would be considered, one could
get full control over backlinks. It seems tedious at first. It need
not be.

Let us say I am in the set of elementary objects named "Body" and I am
inserting links there. The set itself is the list of elementary
object. A function to insert hyperlink can in same time record which
other elementary object is inserted in which object and keep it in the
set list. This way record remains for later back linking. The link can
know where it was linked from.

When handling database objects hyperlinking and backlinking is a must
and mostly built-in.
