Processor for RML (R2RML extension) in Java based on DB2Triples
The processor can be run using Maven, so make sure you have installed it first: http://maven.apache.org/download.cgi You can run a mapping process by executing the following command.
mvn exec:java -Dexec.args="<sources_properties> <mapping_file> <output_file> [<graph>]"
With
<sources_properties> = Java properties file containing key-value pairs which configure the data sources used in the mapping file.
<mapping_file> = The RML mapping file conform with the [RML specification](http://semweb.mmlab.be/ns/rml)
<output_file> = The file where the output RDF triples are stored; default in [Turtle](http://www.w3.org/TR/turtle/) syntax.
<graph> (optional) = The named graph in which the output RDF triples are stored.
An example <sources_properties> file sources.properties could contain:
#File: sources.properties
file1=/path/to/file1.csv
file2=/path/to/file2.json
file3=/path/to/file3.xml
