PHP Notation3 Parser

This parser can parse a subset of n3, reporting triples to a callback function or constructing a RAP Model ( http://www.wiwiss.fu-berlin.de/suhl/bizer/rdfapi )

Supported N3 features:

  • Standard things, repeated triples ( ; and , ), blank nodes using [ ], self-reference ('<>')
  • @prefix mappings
  • = maps to owl#sameAs
  • a maps to rdf-syntax-ns#type
  • Literal datytype- and xmlLanguageTag support
Un-supported N3 Features include:
  • Reification using { }
  • . and ^ operators for tree traversal
  • Any log operators, like log:forAll etc.

This parser is based on n3.py from Epp released 2nd March, 2002. by Sean B. Palmer ( http://infomesh.net/2002/eep/20020302-013802/n3.py )
