Hi,
the resource needs to have rdf:type sp:Select (or sp:Ask etc). Could you
send me the part of the (Turtle) source code that defines that resource,
or (even better) print out the rdf:types of the resource in the Jena model?
Thanks,
Holger

Hi,
I'm trying to convert a file of SPIN query in RDF to raw SPARQL query
with the API.
I used
com.hp.hpl.jena.rdf.model.ModelFactory.createDefaultModel().read(InputStream,
String, String).createResource() to convert SPIN query to
com.hp.hpl.jena.rdf.model.Resource.
Converting to com.hp.hpl.jena.rdf.model.Resource might be successful
(com.hp.hpl.jena.rdf.model.Resource.getModel().write(Writer) runs well).
However, SPINFactory.asQuery(com.hp.hpl.jena.rdf.model.Resource)
returned null.
What is wrong? The RDF file is right.
