JSON To Neo4j

This is a script that reads from a json file output by Dibakar's Clinical Case Report parser.

Prerequisite

Python 3.3+, neo4j 3.3.x, neomodel package

Format

The format of the JSON file is

{
    "nodes": [
        {
            "id": str,
            "type": str,
            "name": str,
            "icolor": str,
            "degree": int
        },
        ...
    ],
    "links": [
        {            
            "id": str,
            "name": str,
            "value": float,
            "source": str,
            "source_name": str,
            "target": str,
            "target_name": str
        },
        ...
    ]
}

Element of nodes or links represents a node or a relation in Neo4j respectively.

Usage

1. Start your Neo4j database.

2. Put your database information in dbConfig.py.

3. Run the following command.

   python jsonToNeo4j.py yourFilename.json 

4. Now you can query results in Neo4j's console. For example:

   MATCH (n) MATCH (n)-[r]-() RETURN n, r LIMIT 20;

Limitations

• Almost no error checking
