Hello I am trying to add an object property between this two individuals. I also have the
object property in the code and the individuals are in the ontology. In only need to
connect them using a property. The individuals look like this in the code, my problem is
that I have never work with that ontologies using this "Description" tag.

I have tried with this code but the getters give me null values. Getting the
two individuals by its names, getting the object property and adding them to
the model.
Individual doc = model.getIndividual("n6356");
Individual ref = model.getIndividual("n6399");
ObjectProperty cites =
model.getObjectProperty("http://purl.org/ontology/bibo/cites";);
model.add(doc,cites,ref);
You have to use the full URI to find the individuals,
String NS = "http://vivo.iu.edu/individual/";;
Individual doc = model.getIndividual(NS + "n6356");
Individual ref = model.getIndividual(NS + "n6399");
ObjectProperty cites =
model.getObjectProperty("http://purl.org/ontology/bibo/cites";);
model.add(doc,cites,ref);
