One small suggestion about the wording of the comment: Instead of ``Edit

``Edit the line below to adjust the amount of memory for Fuseki`` for people 
who are not familiar with Java memory management and could assume the total

The other case is the default in-memory dataset ({{DatasetFactory.create()}}.

It's a one line change to {{DatasetGraphMap.listGraphNodes}} to make not reveal 
empty graphs. 

{{containsGraph}} already works - it looks for quads not for graph in the map. 
(It could be slightly done as an override.)

JENA-1500 and PR#376 (which includes datasets tests including for here).

The JSON ecosystem moves fast! GraphQL is now significant and how that 
might be used is also very interesting. There are different ways to use GraphQL 
and maybe it is not the solution to all needs anyway - this ticket is more 
about result sets in easy-to-consume JSON than other work in the GraphQL-RDF 
area and more about JSON services.

To move this ticket forward, how about putting the feature in with a big 
label saying "Experimental - subject to change" and _really_ mean it?  By 
getting it out, it generates feedback, requirements and insight. 

You can ask for result sets in JSON but the JSON 
(http://www.w3.org/TR/sparql11-results-json/) or JSON-LD graphs but that isn't 
what general data consumers would consider to be "easy-to-consume".

Is the RDF literal to JSON aligned with:
[RDF-JS 
mapping](http://jena.staging.apache.org/documentation/query/javascript-functions.html#arguments-and-function-results)?
 (which only came along recently).

> 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.
