alt Hacker NewsI think you’re misunderstanding the overall architecture here. Instead of syncing the whole tree of strings, the way you would generally represent a PKM with Yjs is to make each logical document a Yjs document (especially given the assumption that offline periods are short.)
You could still build a server-side search index over those documents, which never needs to be sent to the client.
this gives up relational query, i.e. you knowledge graph is no longer a graph. Notion, Roam and Tana all require relational query. What real world app category are you attempting to model that matches document structure? If the domain can be modeled as topic documents and the documents are small, like an individual google doc, sure this set of constraints may be useful. But that does not match PKM!
