Andy Seaborne commented on JENA-632:
------------------------------------
That output can be obtained currently using "application/sparq-results+json".
It's OK but I wouldn't describe it as idiomatic JSON. My mental use cases are
slurping results up in a browser-based application, or reading from some
programme that really does not know much about RDF and different types of RDF
terms.
For {{QueryExecution.execJsonItems}}, how about making the return type
{{Iterator<JsonObject>}}? The iterator is one element per row e.g.:
{noformat}
{
"author" : "J.K. Rowling" ,
"title" : "Harry Potter and the Order of the Phoenix"
}
{noformat}
and that can be turned into output bytes by printing "\[", each object
(separated by ","), and a "\]". In fact, there is a stream write for JSON :
{{JSWriter}} (it's pretty low level : e.g. startArray/finishArray, with each
array element being startObject/finishObject).
How does that sound?

> Project: Apache Jena
> Issue Type: Improvement
> Components: ARQ, Fuseki
> Reporter: Andy Seaborne
> Priority: Minor
> Labels: java, javacc
>
> The capability to generate JSON directly from a SPARQL (or extended SPARQL)
> query would enable the creation of JSON data API over published linked data.
> This project would cover:
> # Design and publication of a design.
> # Refinement of design based on community feed
> # Implementation, including testing.
> # Refinement of implementation based on community feed
> Skills required: Java, some parser work, design and discussion with the user
> community, basic understanding of HTTP and content negotiation.
