Standard Specification

Notation3, or N3 as it is more commonly known, is a shorthand non-XML serialization of Resource Description Framework models, designed with human-readability in mind: N3 is much more compact and readable than XML RDF notation. The format is being developed by Tim Berners-Lee and others from the Semantic Web community. A formalization of the logic underlying N3 was published by Berners-Lee and others in 2008.[1]

N3 has several features that go beyond a serialization for RDF models, such as support for RDF-based rules. Turtle is a simplified, RDF-only subset of N3.


This RDF model in standard XML notation

  <rdf:Description rdf:about="">
    <dc:title>Tony Benn</dc:title>

may be written in Notation 3 like this:

 @prefix dc: <>.
   dc:title "Tony Benn";
   dc:publisher "Wikipedia".

(This example would also be valid Turtle.)
