No need to write the package name - add an import then this code can be
shorter.
> Extend CONSTRUCT to build quads
> -------------------------------
>
> Key: JENA-491
> URL: https://issues.apache.org/jira/browse/JENA-491
> Project: Apache Jena
> Issue Type: Improvement
> Components: ARQ, Fuseki
> Reporter: Andy Seaborne
> Labels: gsoc, gsoc2015, java, linked_data, rdf, sparql
>
> This would be an extension to SPARQL.
> 1/ Add use of GRAPH inside a CONSTRUCT template see SPARQL Update.
> 2/ Add conneg for quads to Fuseki.
> 3/ New QueryExecution operations execConstructQuads() and
> execConstructDataset()
> If asked for triples, and the CONSTRUCT generates quads, the named graph
> items are dropped - that is, only the default graph is returned. This is for
> commonality with RIOT.
