Driver

The complete technical documentation is here

Preprocessor - for Namespaces and Extended functionality

Note: to use extended functionality such as the following you need to include the preprocessor.

@Relationship
Map<List<String>,Map<String,OtherNodeClass>> crazyRelationship;

This preprocessor also requires an additional configuration of your settings.xml file as detailed in the documentation here.

FAQ

• What is the difference to Spring Data Neo4j?
  • Spring Data Neo4j is as well an object to graph mapper for accessing a Neo4j database from Spring applications. The Spring Data connector executes a lot of sanity checks and is for this far slower then our implementation. In addition to that we support additional features as namespaces.
• What are namespaces?
  • Namespaces are a concept to group information. You may know this concept from XML. We introduced this concept to graph databases to dynamically extend persistet information. Like this we also support multiple inheritance in our database model and are so able to only load the required information in the application with minimal memory consumption in the database.
