Turtle is a W3C Candidate Recommendation

The W3C RDF Working Group has published a Candidate Recommendataion of Turtle
– A Terse RDF Triple Language<http://www.w3.org/TR/2013/CR-turtle-20130219/>.
This document defines a textual syntax for RDF called Turtle that allows an
RDF graph to be completely written in a compact and natural text form, with
abbreviations for common usage patterns and datatypes. Turtle provides
levels of compatibility with the existing N-Triples
format<http://www.w3.org/TR/rdf-testcases/#ntriples>as well as the
triple pattern syntax of the
SPARQL <http://www.w3.org/TR/sparql11-query/> W3C Recommendation.
