Hey,
I've upgraded to Jena 2.11.0 as part of SPIN API 1.3.1. As a result,
previously working RDF/XML output breaks:
com.hp.hpl.jena.shared.BadURIException: Only well-formed absolute
URIrefs can be included in RDF/XML output: <#> Code:
57/REQUIRED_COMPONENT_MISSING in SCHEME: A component that is required
by the scheme is missing.
com.hp.hpl.jena.xmloutput.impl.BaseXMLWriter.checkURI(BaseXMLWriter.java:820)
com.hp.hpl.jena.xmloutput.impl.BaseXMLWriter.xmlnsDecl(BaseXMLWriter.java:339)
com.hp.hpl.jena.xmloutput.impl.Basic.writeRDFHeader(Basic.java:64)
com.hp.hpl.jena.xmloutput.impl.Basic.writeBody(Basic.java:47)
com.hp.hpl.jena.xmloutput.impl.BaseXMLWriter.writeXMLBody(BaseXMLWriter.java:492)
com.hp.hpl.jena.xmloutput.impl.BaseXMLWriter.write(BaseXMLWriter.java:464)
com.hp.hpl.jena.xmloutput.impl.BaseXMLWriter.write(BaseXMLWriter.java:450)
com.hp.hpl.jena.rdf.model.impl.ModelCom.write(ModelCom.java:333)
org.graphity.processor.provider.OntologyProvider.getOntModel(OntologyProvider.java:122)
I really hope I can work around this as I spent the whole weekend
upgrading to 2.11.0 :/
This seems to be related to relative URIs of the form <#>. Attached is
the code to reproduce the issue:
Model test = ModelFactory.createDefaultModel();
test.read("jena-test.ttl");
test.write(System.out, "RDF/XML");
jena-test.ttl content:
@base <http://localhost:8080/graphity-client/> .
@prefix : <#> .
@prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#> .
<.> rdfs:isDefinedBy : .
