If so, I assume this is for CONSTRUCT and DESCRIBE queries? If so, then I think you need to be aware that DBpedia (major Linked Open Data hub) and Virtuoso (the RDF supporting DBMS behind DBpedia) have long supported JSON-LD results formats [1] for the aforementioned Query Types. When dealing with SELECTs, the results format is a tabular representation, and in this case you have XML or JSON representations [2]. What isn't offered is a JSON-LD based self-describing SPARQL result which is a consequence of this not really being part of the SPARQL spec. That said, we implemented Turtle, RDF/XML, and N-Triples support ourselves, and will simply add JSON-LD support for completion, in due course.
