Notation3


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.
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.

Examples

The following is an RDF model in standard XML notation:

xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
xmlns:dc="http://purl.org/dc/elements/1.1/">

Tony Benn
Wikipedia



may be written in Notation3 like this:

@prefix dc: .

dc:title "Tony Benn";
dc:publisher "Wikipedia".

This N3 code above would also be in valid Turtle syntax.
