Jena, in the current development builds, has integrated support for
JSON-LD. This includes Fuseki.
The core engine is com.github.jsonld-java:jsonld-java by Tristan King
and Peter Ansell [1]; they did the real work of implementing the
algorithms of the JSON-LD spec. Jena integrates with names for JSON-LD,
a reader and a writer (no special initialization necessary).
JSON-LD output is currently a fixed algorithm for turning a model into a
JSON-LD document. Patches welcome.
The code check that the new dependency is on the classpath. jsonld-java
itself depend on com.fasterxml.jackson [2] for JSON parsing and writing.
The Jena integration is tracked as JENA-634.
Have fun,
Andy
