return model as json

Hi,

There is ResultSetFormatter.outputAsJSON to return the result set (from SELECT command) as JSON response to the client.

For CONSTRUCT and DESCRIBE commands, they are returning Model instead of ResultSet, is there a similar helper function to return the JSON response back to client?



Thanks,

Z

Thanks Andy! Right after I posted this question, I found the solution online, http://t6188.apache-jena-user.apacheforum.info/writing-jena-model-out-as-json-t6188.html
I just tried it, model.write(stream, "RDF/JSON") works like a charm!

Thanks,
Z

Models can be written as JSON-LD or as RDF/JSON.

(You may find it useful to see the result handling in Fuseki2)
