I'm stuck with this version because the latest SPIN API (1.4.0) is
using it and last I heard Holger said he's not planning an upgrade :/
Does it matter?
2.12.0 has JSON-LD.
I registered the writer like this:
RDFLanguages.register(RDFLanguages.JSONLD);
RDFWriterRegistry.register(new RDFFormat(RDFLanguages.JSONLD), new
So you have only registered the writer.
(Why are you trying to read JSON-LD?)
JSONLDWriterFactory(jsonLdTemplates));

I can do a pre-check by attempting
ModelFactory.createDefaultModel().getReader() and catching the
exception. But it's not very elegant.
That seems to be a way of doing it.

Unclear.
1/ 2.11.0 is old. Use a later version with JSON-LD built-in.
2/ You may need to use RDFDataMgr.
Not sure at 2.11.old whether Lang registration interacted with the Jena
RDFReaderFImpl.
3/ Not clear what you registered and how.
4/ Did you call RIOT.init()? Maybe needed.

Hey,
I have a situation where I register a new Lang (JSON-LD) in Jena
2.11.0 but I only have a Writer for it, not a Reader. How can I check
whether Reader exists for a certain Lang before doing the actual read?
Right now I get an exception:
com.hp.hpl.jena.shared.NoReaderForLangException: JSON-LD
at
com.hp.hpl.jena.rdf.model.impl.RDFReaderFImpl.getReader(RDFReaderFImpl.java:100)
at com.hp.hpl.jena.rdf.model.impl.ModelCom.read(ModelCom.java:274)
Thanks,
Martynas
