Hi Andy,
Many thanks for your prompt reply.
Mine is below.
> It's OpGraph for GRAPH.
Thanks. Any documentation reference?
I tried the code in updated gist (lines 37-41) but I get error
org.apache.jena.sparql.ARQInternalErrorException:
QueryIterGraphInner.buildIterator: Not a URI or blank node: {?b
@<http://purl.org/dc/elements/1.1/title> ?title}
> I can't see where the dataset is loaded.
Sorry, I missed that line during copy/paste from my actual code, now the gist
is updated (line 14)
> You don't get a "title" because the BGP is "?g dc:date ?date". Just adding it

I imagine title will be set when I understand how to specify the GRAPH part of
the query.
Sorry for the many questions, but documentation is extremely lacking in ARQ
coverage :/
