The use of other serializations formats (such as TURTLE) results in all triples of all graphs being written away to that file. When setting the flag `filePerGraph` to `true` for serialization formats that do not support graphs, however, the value for `outputFile` will be used to create a directory in which a file will be created for each graph in the RDF dataset.\n\nNote that you cannot use both `CSVFiles` and `connectionURL` at the same time. For each CSV file, the name of the table will be the base name of that file.\n\n## Example\n\nThe directory `example` contains an example of a mapping and configuration file. The example assumes the MySQL database to be called `r2rml`, be running on `localhost` and accessible to the user `foo` with password `bar`. The configuration file looks as follows:\n\n```\nconnectionURL = jdbc:postgresql://my-postgres:5432/\nuser = foo\npassword = bar\nmappingFile = /data/mapping.ttl\noutputFile = /data/output.ttl.gz\nformat = TURTLE\n``` \n**Hint:** my-postgres is the name of the link from the docker command above\n\nThe output, after passing the properties file as an argument to the R2RML processor, should look as follows:\n\n```\n\n a ;\n \"SMITH\" .\n```\n\n## Function with R2RML-F\nThis implementation of R2RML re-implemented the ideas presented in [1], allowing one to declare and use functions in ECMAScript as (Function Valued) TermMaps in the mapping. R2RML-F extends R2RML's vocabulary with predicates for declaring functions, function calls and parameter bindings. These are declared in the namespace [rrf](http://kdeg.scss.tcd.ie/ns/rrf/index.html).\n\n```\n@prefix rr: .\n@prefix ex: .\n@prefix rrf: \n\n<#TriplesMap1>\n rr:logicalTable [ rr:tableName \"EMP\" ];\n rr:subjectMap [\n rr:template \"http://data.example.com/employee/{EMPNO}\";\n rr:class ex:Employee;\n ];\n rr:predicateObjectMap [\n rr:predicate ex:name;\n rr:objectMap [ rr:column \"ENAME\" ];\n ];\n rr:predicateObjectMap [\n rr:predicate ex:test;\n rr:objectMap [\n\t rrf:functionCall [\n\t \t\t\trrf:function <#Concat> ;\n\t \t\t\trrf:parameterBindings (\n\t \t\t\t\t[ rr:column \"ENAME\" ]\n\t \t\t\t\t[ rr:column \"EMPNO\" ]\n\t \t\t\t) ;\n\t \t\t] ; \n\t \t]\n ] \n .\n \n<#Concat>\n\trrf:functionName \"concat\" ;\n\trrf:functionBody \"\"\"\n\t\tfunction concat(var1, var2) {\n\t\treturn var1 + \" \" + var2 ;\n\t}\n\t\"\"\" ;\n.\n```\n\n## License\nThis implementation of R2RML is written by [Christophe Debruyne](http://www.christophedebruyne.be/).\n\nThis code is copyrighted by [ADAPT - Trinity College Dublin](http://www.adaptcentre.ie/) and released under the [MIT license](http://opensource.org/licenses/MIT).\n\n## References\n\n[1] C.
