I think the composite properties like hashmap is very important. Json format data is very important and general data format, for example, now i have a json data or an php array data,they are both nested,but i want to import them into neo4j,but I found it's difficult,even important,the essential reason is neo4j can't support comosite properties,so i have to give up neo4j.
