Hi Minto
Some time ago I implemented a small tool for Stanbol that allows to
create RDF Facades over Clerezza TripleCollections [1].
Facades are interfaces with RDF annotations (see [2] for examples).
Facades are used by
1. creating an instance of the RdfEntityFactory based on a Clerezza MGraph
2. creating instances of the facade by using the RdfEntityFactory
Here some sample code (see [3] for more examples)
MGraph graph; //the RDF data
RdfEntityFactory factory = RdfEntityFactory.createInstance(graph);
Iterator<Triple> textAnnotations =
grpah.filter(null,RDF.type,FISE.textAnnotation);
while(textAnnotations.hasNext()){
UriRef uri = textAnnotations.next().getSubject();
TextAnnotation textAnnotationFacade = factory.getProxy(
uri, TextAnnotation.class);
}
I do not know CXF, but maybe if you annotate the Interfaces with both
the RDF and JAXB annotations it could work as requested.
