Running the IEML_TO_NEO4J script

This script Parses a given IEML Ontology JSON file and feeds the Neo4j DB Nodes and RELATIONS accordingly:

python3 api/ieml_to_neo4j.py

Before running the script you must :

• Run a Neo4j DB (see next chapter)
• Set in the api/ieml_to_neo4j.py
  file these 3 params:

• ontology_id
• ontology_name
• json graph file path

if __name__ == "__main__":
    ontology_id = "1"
    ontology_name = "IEML Grammar"
    parse_json_and_feed_neo4j("iemlgraph.json", ontology_id, ontology_name)

Running the Neo4j DB

There are 2 ways to run a persistent Neo4j DB :

• Locally with a docker
• Remotely with a Neo4j AuraDB cloud already set up

Locally with a docker

Clone this Neo4j 4.4.0 repo : docker repo

run docker-compose up

Open http://127.0.0.1:7474/browser/ to view it in the browser.

In the browser, for the first time, you have to update the password of the DB :

The first time enter that:

• User: neo4j
• Password: foobar

Then it will ask you to set up the new password:

• foobar

In ieml_to_neo4j.py:

DB_URL = os.getenv("DB_URL", "bolt://neo4j:foobar@localhost:7687")

Remotely with a Neo4j AuraDB cloud already set up

Neo4j AuraDB cloud DB has been set up : https://console.neo4j.io

Credentials to login to the account and access the DB browser:

• Email: fredzingg@gmail.com
• Password: Ieml-sandbox-27

Can access to the IEML-neo4j by clicking on the Open with -> Neo4j Browser

In ieml_to_neo4j.py:

## Permanent cloud Neo4j DB 
# DB_URL = os.getenv(
#     "DB_URL",
#     "neo4j+s://neo4j:MZaKywDYwm1CdjnI_b5oFwF9Zi8CEwZPhT9nbRdEcOs@ea862a8f.databases.neo4j.io",
