Hi Jan Erik,
Nice to see you here on the list! Welcome!
Short answer: Serialize to the id of node, then use neo.node[id] to
unserialize.
I haven't thought about support for pickle before, but that could be a nice
addition. The above is (roughly) what it would do. The main difference being
that the pickled state would have to keep track of the neo4j instance as
well since there potentially could be multiple neo4j instances, but that is
doable, since the neo4j instances are uniquely identified by their
resource-uri (the path where the data is stored).
Cheers,
Tobias
