Hey, I've planned to look at Hibernate OGM as a side project but there are no plans for when it will happen.
Could you please explain what you mean by ? #1 " If not then I think wouldn't it be good to support them" #2 "s every organization may not want to go for Spring-Data or want to migrate to Neo4J just because its more efficient than RDBMS" for your second question: Neo4j supports much richer domain models than relational databases. Putting a such domain model in a relational database would lead to sparse table with non-enforced foreign key constraints (optional properties and optional relationships) So it is not likely that you would want to migrate your domain model 1:1 from a relational db to Neo4j. Rather create your _real_ domain model and store that in Neo4j (lots of data and relationships from the real domain get dropped b/c they don't really fit in the more strict and limited rdbms schema). That said, there is a SQL Loader tool written by Peter Neubauer, that _can_ be used to convert relational databases to neo4j.
