Shouldn't PNAME_NS be COLON? PNAME_NS matches `foo:` so "s = String() <
PNAME_NS >" matches `"abcd" xyz:`

some javacc ability to switch details may be needed.
> Generate JSON from SPARQL directly.

> 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.
