> 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.
