I have some csv data as below. And I generated a .ttl file using Jena and the code is below-
Property movieName = movieModel.createProperty("http://imdb.com/property/movie");
Property countryName = movieModel.createProperty("http://imdb.com/property/country");
for (int i = 0; i < movieDataCSV.size(); i++) {
Resource resource = movieModel.createResource("http://imdb.com/actor/" + actors.get(i));
resource.addProperty(movieName, movies.get(i));
resource.addProperty(countryName, countries.get(i));
}
movieModel.write(System.out, "TURTLE");
try {
Writer fileWriter = new FileWriter("/Users/gowthamibhogireddy/Downloads/csv2rdfdata.ttl");
movieModel.write(fileWriter, "TURTLE");
} catch (Exception e) {
e.printStackTrace();
}
int counter = 0;
StmtIterator iterator = movieModel.listStatements();
while (iterator.hasNext()) {
Statement stmt = iterator.next();
Resource subject = stmt.getSubject();
Property predicate = stmt.getPredicate();
RDFNode object = stmt.getObject();
counter++;
System.out.print(counter + ". ");
System.out.print(subject.toString());
System.out.print(" " + predicate.toString() + " ");
if (object instanceof Resource) {//check to see if object is is an instance of Resource
System.out.print(object.toString());
} else {
System.out.print(" \"" + object.toString() + "\"");
}
System.out.println(" ");
}
}
But when I try to import this into GraphDB, i get this error -https://stackoverflow.com/questions/62230117/error-org-eclipse-rdf4j-sail-sailexception-invalid-iri-value
How can I solve this? I need a CSV to RDF converter that helps me to import data onto graph db?
