I suggest to use sp:text instead of SPIN RDF syntax here. Why do you
need that specific syntax?
Otherwise, why not just use TBC Free edition for such conversion tasks?

Hi Holger,
Thank you. Given that there is no such command line option, I am
trying to adapt the example to translate a INSERT DATA to SPIN notation.
===
public class SPINParsingExample {
public static void main(String[] args) {
// Register system functions (such as sp:gt (>))
SPINModuleRegistry.get().init();
// Create an empty OntModel importing SP
Model model = ModelFactory.createDefaultModel();
model.setNsPrefix("rdf", RDF.getURI());
model.setNsPrefix("ex", "http://example.org/demo#";);
String query =
"SELECT ?person\n" +
"WHERE {\n" +
" ?person a ex:Person .\n" +
" ?person ex:age ?age .\n" +
" FILTER (?age > 18) .\n" +
"}";
Query arqQuery = ARQFactory.get().createQuery(model, query);
ARQ2SPIN arq2SPIN = new ARQ2SPIN(model);
Select spinQuery = (Select) arq2SPIN.createQuery(arqQuery, null);
System.out.println("SPIN query in Turtle:");
model.write(System.out, FileUtils.langTurtle);
System.out.println("-----");
String str = spinQuery.toString();
System.out.println("SPIN query:\n" + str);
// Now turn it back into a Jena Query
Query parsedBack = ARQFactory.get().createQuery(spinQuery);
System.out.println("Jena query:\n" + parsedBack);
}
}

I started thinking that it would be enough to change the lines:
model.setNsPrefix("rdf", RDF.getURI());
model.setNsPrefix("wn30", "https://w3id.org/own-pt/wn30/schema/";);
model.setNsPrefix("wn30pt", "https://w3id.org/own-pt/wn30-pt/instances/";);
String query = "INSERT DATA { graph <file://own-pt.nt
<file://own-pt.nt/>> { wn30pt:synset-13299651-n wn30:containsWordSense
[ rdfs:label \"pagamento\"@pt ; rdf:type wn30:WordSense ; wn30:word
wn30pt:word-pagamento ] . wn30pt:word-pagamento wn30:lexicalForm
\"pagamento\"@pt ; rdf:type wn30:Word . } }";
But I was wrong! The lines
Query arqQuery = ARQFactory.get().createQuery(model, query);
ARQ2SPIN arq2SPIN = new ARQ2SPIN(model);
Select spinQuery = (Select) arq2SPIN.createQuery(arqQuery, null);
Also need to be changed, right? How? What classes to use?
Best,
Alexandre
