Hi Andy, I have followed the tutorials about SPARQL and RDF and I found them very interesting. I think I'm very confident to work with these technologies. In the tutorials I have used jena-arq sparql processor and jena fuseki server as well. I have check out the jena development code base as well. In order to modify the jena-arq and jena-fuseki so that SPARQL query can result in RDF Dataset instead of RDF graph which modules in the code base I should look into?
I'm considering to start create the project proposal, can you please mention the specifics that need to be in the proposal?
