Rem Collier commented on JENA-2134:
-----------------------------------
Hi Rob,
I have added the code I used to printout the model.
The output is generated by RDF4J which is being used on a server (not written
by me). The triples are inserted into its knowledge store using SPARQL
statements. I have just used the default TURTLE Formatter provided with RDF4J
to format the output.
The server code is open source and can be found here:

environment (github.com)|https://github.com/bold-benchmark/bold-server]
> Model loads incorrectly from ttl file
> -------------------------------------

> Key: JENA-2134
> URL: https://issues.apache.org/jira/browse/JENA-2134
> Project: Apache Jena
> Issue Type: Bug
> Components: Jena
> Affects Versions: Jena 4.1.0
> Environment: Windows, WSL2, Maven, Java 14.0.2
> Reporter: Rem Collier
> Priority: Major
> Attachments: example.ttl
>
>
> I downloaded knowledge from an RDF4J data store in triple format. I stored
> the content in a file called example.ttl.
> When I try to load the file, the composite resources do not get generated,
> resulting in some triples not being added to the model.
> The code I run is:
> {code:java}
> Model model = ModelFactory.createDefaultModel();
> model.read("example.ttl");
> {code}
> {{The output is:}}
> {code:java}

> Property predicate = stmt.getPredicate();
> RDFNode object = stmt.getObject();
> System.out.print(subject.getLocalName());
> System.out.print(" " + predicate.getLocalName() + " ");
> if (object instanceof Resource) {
> System.out.print(object.toString());
> } else {
> // object is a literal
> System.out.print(" \"" + object.toString() + "\"");
> }
> System.out.println(" .");
> } {code}
