[jira] [Commented] (JENA-2134) Model loads incorrectly from ttl file

["Rob Vesse (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/JENA-2134?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17380136#comment-17380136 ] 

Rob Vesse commented on JENA-2134:
---------------------------------

You haven't shown how you have generated that output.

I note that a number of your triples are using blank nodes as their subjects so if you are iterating over the statements in the model and assuming everything has a URI subject then you are going to get {{null}} as your output because those triples have a blank node subject

> 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}
