    Just `new HashMap<>` is okay after Java 7.


> Extend CONSTRUCT to build quads

>                 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.
