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.
The following is an RDF model in standard XML notation: may be written in Notation3 like this: This N3 code above would also be in valid Turtle syntax.
