Load LUBM University data to Neo4j

I am trying to upload LUBM data set to Neo4j server. I went through neo4j tutorial and there is something called 'batch import'. To use that I should have two CSV files.

  1. Nodes.CSV
  2. Relations.CSV

The problem is in University data set there are nodes from multiple types(University, Department, Professor). So I think I cannot do it using single nodes.CSV file. I think someone should have done this before. Great if someone can help me to load LUBM data.

Perhaps you can share a link to the original dataset. In general for batch import there is comprehensive documentation (including examples) available:

You need several .csv file per type/label and make sure to conform the following specification:

CSV file format

The CSV file to use with LOAD CSV must have the following characteristics:

  • the character encoding is UTF-8;
  • the end line termination is system dependent, e.g., it is \n on unix or \r\n on windows;
  • the default field terminator is ,;
  • the field terminator character can be change by using the option FIELDTERMINATOR available in the LOAD CSV command;
  • quoted strings are allowed in the CSV file and the quotes are dropped when reading the data;
  • the character for string quotation is double quote ";
  • the escape character is .
