Deserialize object as plain identifier object property value

[ledsoft]

It would be nice to be able to deserialize full blown objects as values of identifier-base object property. For example

{
  "@id": "http://krizik.felk.cvut.cz/ontologies/jb4jsonld#UNSC",
  "@type": "http://krizik.felk.cvut.cz/ontologies/jb4jsonld/Organization",
  "brands": [
    "Spartan-II",
    "Mjolnir IV"
  ],
  "http://purl.org/dc/terms/created": "Mon Aug 01 10:43:04 CEST 2016",
  "http://www.w3.org/2000/01/rdf-schema#label": "UNSC"
}

Deserialize as value of:

...
@OWLObjectProperty(iri = "http://krizik.felk.cvut.cz/ontologies/jb4jsonld/isMemberOf")
private URI employer;   // Would be http://krizik.felk.cvut.cz/ontologies/jb4jsonld#UNSC
...

This would simulate the application working with a smaller model than that available in the JSON-LD data.
