org.apache.jena.riot
Class RDFDataMgr

java.lang.Object
  org.apache.jena.riot.RDFDataMgr

public class RDFDataMgr
extends Object
extends Object

General purpose reader framework for RDF (triples and quads) syntaxes.

HTTP Content negotiation
File type hint by the extension
Application language hint

It also provides a way to lookup names in different locations and to remap URIs to other URIs.

Extensible - a new syntax can be added to the framework.

Operations fall into the following categories:

read -- Read data from a location into a Model/Dataset etc
loadXXX -- Read data and return an in-memory object holding the data.
parse -- Read data and send to an StreamRDF
open -- Open a typed input stream to the location, using any alternative locations
write -- Write Model/Dataset etc
