USASpending tarql mapping

Mapping for CSV data from USASpending to RDF via tarql.

Use

Download a release of tarql, extract and use the script bin/tarql to execute the transformation. Invoke the transformation using the mapping (mapping.sparql) from command line:

bin/tarql mapping.sparql USASpending.csv

Issues

  • Since tarql doesn't support streaming processing, you may encounter Java's OutOfMemoryError when working with bigger data on a smaller machine. When you're dealing with larger CSV's, consider increasing Java heap space (e.g., set JAVA_OPTS="-Xms128m -Xmx1024m") or splitting the source data into multiple files to be processed separately.
