RDF Serialization

N-Triples RDF Test Cases, W3C Recommendation, 25 February 2014 a line-based, plain text serialization format for storing and transmitting RDF data

Notation 3 (N3)

a shorthand non-XML serialization of RDF models, designed with human-readability in mind

much more compact and readable than XML RDF notation

Turtle (Terse RDF Triple Language)

W3C Candidate Recommendation, 25 February 2014 a format for expressing data in the Resource Description Framework (RDF) data

model a subset of Notation3 (N3) language, and a superset of the minimal N-Triples format
