[jira] Created: (CLEREZZA-415) RDF/JSON Parser can not parse
triples with blank node objects when the blank node does not appear as
subject.
RDF/JSON Parser can not parse triples with blank node objects when the blank node does not appear as subject.
-------------------------------------------------------------------------------------------------------------
Key: CLEREZZA-415
URL: https://issues.apache.org/jira/browse/CLEREZZA-415
Project: Clerezza
Issue Type: Bug
Reporter: Daniel Spicar
Priority: Minor
Triples of the form (N-Triples syntax):
<http://example.org/res> <http://example.org/prop> _:a .
can not be parsed. Error message:
java.lang.IllegalArgumentException: Invalid object: null
at org.apache.clerezza.rdf.core.impl.TripleImpl.<init>(TripleImpl.java:50)
at org.apache.clerezza.rdf.rdfjson.parser.RdfJsonParsingProvider.addValuesToGraph(RdfJsonParsingProvider.java:130)
While such triples may not be very interesting semantically, they are nevertheless valid RDF.
If there is a triple of the form (the blank node appears as the subject)
_:a <http://example.org/prop2> "Hello" .
in the graph the parsing succeeds.
