This project can be used alone if you only want to convert a .scar into a Neo4j requests file or directly insert data in neo4j local database.

WARNINGS: 

1) If you want to insert data automatically in a database, you need to have nodeJS installed! 
	Windows: https://nodejs.org/en/ and download + install the last stable version
	Linux: install with your distribution's package manager

2) You need to configure the ../hdoc_to_neo4j/node/config.json file properly to fit with the parameters of the dabase you want to insert in. (host, db and password).

User documentation
------------------

You have to respect the following steps :

1 - Place one or several archives (.scar) in the "input" folder

2 - Run the "runWithNode" file (choose the extension according to your OS)

3 - Admire the graph created with neo4j in your browser (on localhost:7474)
