+ <h2>N′-Triples</h2>
+ <p>This section defines an easy to parse line-based subset of
+Turtle. Currently named N-Triples Prime (<abbr title="N-Triples Prime">N′-triples</abbr>).</p>
+ <p>The syntax is an improved version of N-Triples. N-Triples is a format
+originally defined in the RDF Test Cases [[!RDF-TESTCASES]] document. Its original intent was for
+writing test cases, but it has proven to be popular as a dump format for RDF
+data.</p>

+ <h3>Changes from N-Triples</h3>
+ <ul>
+ <li>Default encoding is UTF-8 rather then US-ASCII only
+ <li>Uses IRIs rather then RDF URI References
+ <li>Defines a unique media type <code>text/ntriples+turtle</code>
+ <li>Subset of Turtle rather then Notation 3
+ </ul>

+ <section id="n-triples-compatibility" class="informative">
+ <h3>Compatibility with previous N-Triples</h3>
+ <p>
+ An N-Triples document written using only absolute IRIs is a valid N′-triples document generating the same triples. N-triples uses <code>\u</code> escape sequences for characters outside US-ASCII and processing will have turned these into the original character. A N′-triples document that is serialized into ASCII and uses <code>\u</code> escape sequences for any character outside US-ASCII should be equivalent to a N-Triples document.
