How to fix file paths in the LUBM generator?

Question

I tried to generate 160000 pieces of data using the LUBM generator.

Unfortunately, the generator wrongly generates backslashes in file paths:

$ java -cp classes/ edu.lehigh.swat.bench.uba.Generator -onto http://asdf.com/xyz
Started...
/home/user/LUBM\University0_0.owl generated
CLASS INSTANCE #: 1657, TOTAL SO FAR: 1657
PROPERTY INSTANCE #: 6896, TOTAL SO FAR: 6896

You can see the wrong path /home/user/LUBM\University0_0.owl

How do I make it generate the correct paths?

Answer 1

You'll have to edit the source code a little. Specifically the src/edu/lehigh/swat/bench/uba/Generator.java

Line 647 of Generator.java contains the part System.getProperty("user.dir") + "\\" +. Change it so that it looks as follows:

private void _generateDept(int univIndex, int index) {
  String fileName = System.getProperty("user.dir") + "/" +
      _getName(CS_C_UNIV, univIndex) + INDEX_DELIMITER + index + _getFileSuffix();
  writer_.startFile(fileName);

This holds for version UBA1.7 of the generator.
