 All properties - and type of relationships - appear in those maps as they would appear in the graph when the entity would
 have been written by SDN.
 Values will have the correct Cypher type and won't need further conversion.

 Talking about relationships: If you have defined relationships in your entity, they will get added to the returned map as https://neo4j.com/docs/cypher-manual/4.0/syntax/lists/#cypher-pattern-comprehension[pattern comprehensions].
 The above return part will then look like:
 
-`RETURN n{.first_name, ..., Person_Has_Hobby: [(n)-[:Has]->(n_hobbies:Hobby)|n_hobbies{{neo4jInternalId}: id(n_hobbies), .name, __nodeLabels__: labels(n_hobbies)}]}`

 The map projection and pattern comprehension used by SDN ensures that only the properties and relationships you have defined are getting queried.
