Well, I have problem to make dynamic RDF.type. The RDF.type should get dynamic
from anotation by user.
This is my static RDF.type code :
Resource thesis = model.createResource(thesisURI)
.addProperty(RDF.type,
semantic.OntologyKomputasi.mechanicalTurk)
.addProperty(DC.creator, creator)
.addProperty(semantic.OntologyKomputasi.anotasiOleh,
anotasiOleh);
So I try to make it dynamic by creating parameter thesisType, but when I run
it, it doesn't want to create RDF.type property.
semantic.OntologyKomputasi is my ontology java code generated from jena
schemagen, and semantic.OntologyKomputasi.mechanicalTurk is class in the
ontology.
String thesisType = "semantic.OntologyKomputasi.mechanicalTurk";
That string is the *name* of your java object, it is neither the object
itself nor the URI of the corresponding resource.
Resource thesis = model.createResource(thesisURI)
.addProperty(RDF.type, thesisType)
You just need some way (such as a hash table) to map from your input
parameter (whatever that is) to either the java Resource object created
by schemagen or to the URI itself.
If you want to pass URI strings around then you can use createResource
again:
String thesisTypeURI = "http//ontology/MechanicalTurk";
Resource thesisType = model.createResource( thesisTypeURI );
Resource thesis = model.createResource(thesisURI)
.addProperty(RDF.type, thesisType)
