All Implemented Interfaces:

org.openrdf.rio.RDFHandler, org.openrdf.rio.RDFWriter

public class JSONLDWriter
extends org.openrdf.rio.helpers.RDFWriterBase

An implementation of the RDFWriter interface that writes RDF documents in the JSON-LD format.

JSON-LD is a JSON-based format for serializing data in (a superset of) RDF as JSON and interpreting JSON contents as RDF. See http://www.w3.org/TR/json-ld/ for the format specification.

Similarly to RDF/XML, JSON-LD provides for several ways to encode the same triples. This RDFWriter adopts a simple and consistent strategy whose output is a JSON-LD document consisting of a sequence of resource blocks, one for each RDF resource of the configured root type (@see JSONLD.ROOT_TYPES).
