Not seen this before. Can you point to where this is defined in the turtle specification?
from rdf4j.
I have just ported code from Jena to RDF4J. In the Jena version, all IRIs I used were properly abbreviated when a namespace prefix was defined. Not so in RDF4J. I tracked this down to two issues:
- SimpleIRI does not retain namespace and localname separately (I could work around this using a custom subclass of AbstractIRI)
- TurtleWriter did not consider the explicit namespace in the IRI
Have a look at the provided test case.
As far as I can see during a quick scan of the Turtle specs, they deal mostly with parsing the turtle format. However, what I am trying to fix here is the serialization. The current serialization done by RDF4J provides valid Turtle, but it is unnecessarily verbose. My change makes more effective use of the namespace prefix declarations, leading to a serialized form that is more compact and easier to read.
