alt Hacker Newsthis 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!
It doesn’t give it up, it just moves that aspect to the server. The server can still build an index over the documents in whatever way it likes, perform expensive queries, and only send the results to the client.
An example that matches that document structure is Figma; each document is individually small enough to be synced with the client, document metadata is indexed on the server, and queries over documents take place on the server.
