Bidirectionality here explicitly tied to Ted Nelson's Xanadu. Call block transclusion in pkm tool transclusion "primitives" which sound like a right charcterisation. Say Latticework differs from both

Ted Nelson felt visible connections between text were the most important part of his Xanadu project.

There are close parallels between these in digital spaces and songlines and related orality based mnemonic techniques.

Discussion of some prior art leading up to Google's text fragment links.

There is some research in link types and citation types to build on, e.g. https://sparontologies.github.io/cito/current/cito.html

An argument for content-based identifiers. I think it's wanted to link different versions of a document with each other to allow for updates

Deep links via content locators, see https://github.com/jakobib/hypertext2019#readme

These "zippered lists" are the first mention of what would later become known as "Xanalogical storage", and ultimately as "transclusions".

But what about links I want to add to documents that I don't own? "Layers for the Web"

Doesn't Xanadu keep stuff separate somehow?
