Neo4j

OptimusKG provides a Docker Compose setup for running Neo4j with the exported graph data.

Start Neo4j

make neo4j

This starts a Neo4j container in the background. Access the Neo4j Browser at http://localhost:7474/browser/preview/.

Export Data

Full Database Export

Export the entire database to a Neo4j-JSONL file:

make neo4j-export

The data is saved to data/export/optimuskg.jsonl.

Query-Based Export

Export results of a specific Cypher query:

CYPHER_QUERY="MATCH (d:Disease) RETURN d" make neo4j-export

Results are saved to data/export/ with a filename derived from the query.

Docker Compose

The Neo4j configuration is defined in docker-compose.yaml at the project root. It uses the APOC plugin for JSON export capabilities.
