> @afs unfortunately, i no longer have the example from the beginning. I
would have to make it again. Let's see if I can do it in the next few days.
Working for money again tomorrow.
I have now tried to recreate the example:
```java
package com.example;
import java.util.UUID;
import org.apache.commons.rdf.api.Graph;
import org.apache.commons.rdf.api.IRI;
import org.apache.commons.rdf.api.RDF;
import org.apache.commons.rdf.jena.JenaGraph;
import org.apache.commons.rdf.jena.JenaRDF;
import org.apache.jena.query.ReadWrite;
import org.apache.jena.rdf.model.Model;
import org.apache.jena.tdb.TDBFactory;
public class Test {
public static void main(String[] args) {
org.apache.jena.query.Dataset jenaDataset =
TDBFactory.createDataset("target/test");
RDF rdf = new JenaRDF();
IRI namePredicate = rdf.createIRI("https://schema.org/name";);
String graphNameAsString = "http://example.com/myGraph";;
IRI myGraphNameAsIri = rdf.createIRI(graphNameAsString);
// READ TDB dataset
Graph myCommonsGraph4Read =
((JenaRDF)rdf).asDataset(jenaDataset).getGraph(myGraphNameAsIri).orElseThrow(()->new
IllegalStateException());
myCommonsGraph4Read.stream().forEach(quad->System.out.println("commonsQuad: " +
quad));
// Write TDB dataset
jenaDataset.begin(ReadWrite.WRITE);
Graph commonsRdfGraph4Write =
((JenaRDF)rdf).asDataset(jenaDataset).getGraph(myGraphNameAsIri).orElseThrow(()->new
IllegalStateException());
IRI randomSubject = rdf.createIRI("http://example.com/"+
UUID.randomUUID().toString());
commonsRdfGraph4Write.add(randomSubject, namePredicate,
rdf.createLiteral("Bob"));
Model jenaModel =
((JenaGraph)commonsRdfGraph4Write).asJenaModel();
jenaDataset.addNamedModel(graphNameAsString, jenaModel);
jenaDataset.commit();
jenaDataset.end();
}
}
```
