RDFWriter is an interface to RDF serializers.
An RDFWriter is a class which serializes an RDF model to some RDF serializaion language. RDF/XML, n-triple and n3 are examples of serialization languages.

General interface for RDF Writer. @author TurnerRX @version $Id: RdfWriter.java 2894 2009-01-27 21:25:13Z newmana $
org.openrdf.rio.RDFWriter
An interface for RDF document writers. To allow RDF document writers to be created through reflection, all implementing classes should define at least two public constructors: one with an {@link OutputStream} argument and onewith an {@link Writer} argument.
