I have to create a web service that needs to interact with a Neo4J database using the Spring framework with Spring-Data-Neo4J. This requires a static data domain model, e.g. defined labels, relations, properties.
The Problem is, that my data is based on an Ontology (via the neosemantics plugin) which could be modified in the future. It would be great if the application could automatically adopt to it. This way, the data model could be extended by editing the ontology only and no additional programming knowledge would be necessary.
Does this mean I have to generate the Spring data classes dynamically (based on the Ontology) or is there a better way to achieve this with Spring-Data-Neo4J (or should I use a different framework)?
I ended up using the Java neo4j driver instead of Spring-Data-Neo4jand a generic node class implementation only having the fields id, list of labels and a map of properties. The set labels and properties can be checked against the ontology prior to creating the nodes in the database. This way I can enforce a specific set of node labels and properties by only modifying the ontology and without having to generate the specific Spring-Data-Neo4j data classes.
