Class AddDataFromCsvFile

java.lang.Object

org.semanticweb.vlog4j.examples.core.AddDataFromCsvFile

public class AddDataFromCsvFile
extends Object

This example shows how facts can be imported from files in the CSV format. Specifically, it imports from a .csv.gz file, but you can also import from .csv files. Moreover, it shows how query answers that result from reasoning over these facts can be exported to .csv files.

For importing, a CsvFileDataSource that contains a path to the corresponding .csv.gz file must be created. A .csv file contains facts in the CSV format over exactly one predicate. A .csv.gz file is the gzipped version of such a .csv file.

For exporting, a path to the output .csv file must be specified.
