Paolo Castagna commented on CLEREZZA-648:
-----------------------------------------
An RDF/JSON parser and serializer (as well as usual Jena readers/writers) have
been added to Apache Jena.
If you want to try or use it, make sure you call RIOT.init() to wire the new
reader|writer into Jena. RIOT is in ARQ at the moment. Then you can use the
usual Jena Model APIs:
public Model write( OutputStream out, String lang ) ;
public Model read ( InputStream in, String base, String lang ) ;
Specify "RDF/JSON" as the lang parameter.

> Project: Clerezza
> Issue Type: Improvement
> Reporter: Daniel Spicar
> Labels: rdf/json, serialization
>
> The serializer loads the entire graph to serialize into memory in order to
> sort it. A solution is likely to depend on the underlying triple collection
> as certain triple collection may be able to provide sorted triples already
> from the underlying triple store. Therefore this issue may require a more
> general solution that affects other modules as well. A proposed solution and
> a detailed analysis is available in CLEREZZA-643.
