Hi Andy,
thanks for your reply. I haven't tried `riot` yet.
I have a Gradle project setup with these dependencies:
```gradle
implementation "org.apache.jena:jena-core:4.7.0"
implementation "org.apache.jena:jena-tdb:4.7.0"
```
Here is the complete, minimal example:
```java
package de.benjaminaaron.ontoengine;
import org.apache.jena.query.Dataset;
import org.apache.jena.query.DatasetFactory;
import org.apache.jena.rdf.model.Model;
import org.apache.jena.rdf.model.ResourceFactory;
import org.apache.jena.rdf.model.Statement;
public class Main {
public static void main(String[] args) {
Dataset dataset = DatasetFactory.createTxnMem();
Model model = dataset.getNamedModel("main");
Statement statement1 = ResourceFactory.createStatement(
model.createResource("http://dev.de/default#Ben";),
model.createProperty("http://dev.de/default#joined";),
model.createResource("http://dev.de/default#ProjectX";)
);
model.add(statement1);
Statement statement2 = ResourceFactory.createStatement(
model.createResource(statement1),
model.createProperty("http://dev.de/default#atLocation";),
model.createResource("http://dev.de/default#Berlin";)
);
model.add(statement2);
System.out.println(statement2.getSubject().isStmtResource()); // -->
false
model.listStatements().toList().forEach(System.out::println); // Output
1 below
model.write(System.out, "TURTLE"); // Output 2 below
}
}
```
`Output 1`
```
[http://dev.de/default#Ben, http://dev.de/default#joined,
http://dev.de/default#ProjectX]
[4f663e1c-cfb5-473d-b0d6-1562534f9601, http://dev.de/default#atLocation,
http://dev.de/default#Berlin]
```
`Output 2`
```
<http://dev.de/default#Ben>
<http://dev.de/default#joined> <http://dev.de/default#ProjectX> .
[ <http://dev.de/default#atLocation>
<http://dev.de/default#Berlin> ] .
```
