Neo4j importer & web importer

Despite the name this repository now contains code for a console based import tool as well as a web based one.

They both import data from node and relationship files which can be either tab or comma delimited.

Building the importer JAR

You can build the importer JAR by using the following command:

mvn clean compile assembly:single

That creates a JAR under target/ which is used by the console based import tool.

Using the console based import tool

Run the following command:

./neo4j-loader

Its default input is two files named 'nodes.csv' and 'relationships.csv' in the current directory which contain nodes and relationships to import. Nodes are referenced in both files using a natural key.

e.g.

nodes.csv

id   									name    age works_on
b8bd1c77-2732-4687-96b3-fa2c9f25e303    Michael 37  neo4j
ac80bc1f-d8e8-40f0-9b53-af731c635796    Selina  14

relationships.csv

Using the web based import tool

Bit esoteric at the moment as it involves changing the neo4j static JAR. Working out how it can be called from within Neo4j browser
