Apache Jena is framework for building linked data and semantic web
applications.

Jena SPARQL server.

Hmm,
My head is spinning a bit now - I’m trying to understand something simple -

So my reading says that is a valid lexical form (in the lexical space) for the

DAWG did at one time work with result sets encoded in RDF for the
testing work.
As the WG progressed, it was clear that implementation of testing
was based on result set comparison, and an impl needed to grok the XML
results encoding anyway. Hence the need for the RDF form dwindled but

There's a practical tradeoff of streaming and whole result processing in
the server.
Streaming can give lower latency to first result for the client which
can be a better user experience. HTTP status code go in the header so
to insert the perfect answer, the server needs to see the end of the
