You posted this in “Knowledge management”, instead of in “Help”. So are you asking for advice on how to implement ideas from Zettlekasten?
Or are you asking technically, how to link notes in Obsidian? In Obsidian links, there is no “parent” and “child”. The link is just a directional link from one note to another note.
A -> B
But you can also have links going both ways. There is no hierarchy. A can have a link to B. And B can have another link back to A. Both can have a link to C. C can have a link to both A and B.
A -> B -> A
If in your knowledge system, you have an idea of what note is the “parent” of another note, you make the link using the exact same method. [[]]. That’s the technical answer.
But if you are asking how to implement a specific direction in your notes, or to make your notes flow in a series to match certain ideas from Zettlekasten, I don’t have any good answers, or I don’t fully understand the question.
“Maps of Content” might help you. On the process of making MOCs It is a concept that I think nickmilo is developing. It’s a way of building a map into your content. So you could create a page of links in order that you can use to show the shape or direction of your notes.
