Package de.fuberlin.wiwiss.ng4j.trig Description

Support for TriG, a serialization format for Named Graphs based on N3/Turtle.

The parser implementation is based on Jena's N3 parser. The parser is generated from an AntLR grammar. The grammar and all of the files generated from it are stored in the parser subpackage.

The parser uses the callback interface TriGParserEventHandler. Its only implementation is the NamedGraphSetPopulator, which processes the parser events and populates a NamedGraphSet.

The serializer uses a copy of Jena's N3JenaWriterPP to write out the individual graphs, with a bit of surrounding code.
