Building the graph

TL;DR

Here's how you build the graph with pre-made CSV files of the graph, ready for batch-import (No need for PostgreSQL):

1. bundle install
2. git submodule update --init
3. rake neo4j:install
4. ./scripts/import_csv.sh

From scratch

1. Download from IMDB their database aka Plain Text Data Files

• Here's a gist I wrote that handles the download from IMDB

2. Run IMDBPy on the "Plain Text Data Files" to create a PostgreSQL database

• Example: imdbpy2sql.py -d /Users/itay/Development/movieawesome/imdbdb -u 'postgres://awesome:1234@localhost/imdb'

3. Run rake export:neo4j_csv to convert the movie data from PostgreSQL to Neo4j export.rake defines the graph and exports it to CSV files, so at the moment this is where the graph can be customised
4. Import the CSV files to neo4j using batch-import

• Example: mvn test-compile exec:java -Dexec.mainClass="org.neo4j.batchimport.Importer" -Dexec.args="sample/batch.properties graph.db movie_nodes.csv,person_nodes.csv,genre_nodes.csv movie_person_relationships.csv,movie_genre_relationships.csv" -X
