RDF/XML Export does not work

[frodeseverin]

Exporting a Knowledge Base as RDF/XML does not work. It only exports the prefixes, but no data.

All other formats work as expected AFIK.

Is this the same issue as AKSW/OntoWiki#114?

The RDF/XML Export is incomplete.

Import the following graph and export it as rdf/xml, it will only contain that <http://example.com> a owl:Ontology.

# Exported with the Erfurt API - http://aksw.org/Projects/Erfurt

@base <http://example.com> .
@prefix rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> .
@prefix ns0: <http://www.w3.org/2002/07/owl#> .
@prefix ns1: <http://example.com/> .

<http://example.com> a ns0:Ontology .

ns1:sub a ns1:class ;
        ns1:pred ns1:obj ;
        ns1:lab "Subject" .
