A Java-based workflow for creating and managing relationships between nodes in a Neo4j graph database, leveraging metadata exported from PostgreSQL. This project focuses on establishing standard meta-data relationships to enhance the graph structure after node insertion.

Features

Automates relationship creation between various node types in Neo4j.
Integrates PostgreSQL data exports with Neo4j graph database.
Modular Java classes for relationship management.
Uses Neo4j Java Driver for database connectivity.
Logging support with SLF4J for process tracking and error handling.

Tech Stack

Java
Neo4j (Graph Database)
PostgreSQL (Data source assumed)
SLF4J (Logging)

Getting Started

Prerequisites

Java Development Kit (JDK) 11 or higher
Neo4j database instance
PostgreSQL database with relevant data
Maven or Gradle for dependency management (assumed)

Installation & Running

Clone the repository:

git clone https://github.com/justin-napolitano/supreme-court-meta-relationships.git
cd supreme-court-meta-relationships

Build the project (assuming Maven):

mvn clean install

Configure Neo4j connection settings in Neo4jConnection class (not included in repo snippet).
Run the RelationshipCreator class to create relationships:

java -cp target/your-jar-file.jar com.supreme_court_transfer.RelationshipCreator

Project Structure

com.supreme_court_transfer.RelationshipCreator - Java class responsible for creating relationships between nodes in Neo4j.
Neo4jConnection (assumed) - Utility class to manage Neo4j sessions.

Future Work / Roadmap

Expand relationship creation to cover additional metadata types.
Implement error recovery and retry mechanisms.
Add configuration options for relationship types and properties.
Provide detailed documentation and examples for integration.
Automate data export from PostgreSQL to Neo4j within the workflow.
Add unit and integration tests for relationship creation methods.
