I have large maps that include nodes as entry values. I want to persist these maps in the DB for subsequent retrieval. I believe the best/only strategy is: 1. Construct a new map where each node in a value is replaced by its node-id() value. 2. Serialize the map to JSON and store as a blob To reconstitute it, do the reverse (parse JSON into map, replace node-ids() with nodes). Is my analysis correct? Have I missed any detail or better approach?
