+
+        <p><a href="http://www.w3.org/TR/rdf11-concepts/#dfn-literal">Literals</a> are used to identify values such as strings, numbers, dates.</p>
+
+
+        <p>
+          Literals (Grammar production <a href="#grammar-production-literal">Literal</a>) have a lexical form followed by a language tag, a datatype IRI, or neither.
+          The representation of the lexical form consists of an initial delimiter <code>"</code> (<span class="codepoint">U+0022</span>), a sequence of permitted characters or numeric escape sequence or string escape sequence, and a final delimiter. Literals may not contain the characters <code>"</code>, <code title="LINE FEED"><sub>LF</sub></code>, or <code title="CARRIAGE RETURN"><sub>CR</sub></code>. In addition '<code>\</code>' (<span class="codepoint">U+005C</span>) may not appear in any quoted literal except as part of an escape sequence.
+          The corresponding <a href="http://www.w3.org/TR/rdf11-concepts/#dfn-lexical-form">RDF lexical form</a> is the characters between the delimiters, after processing any escape sequences.
+          If present, the <a href="http://www.w3.org/TR/rdf11-concepts/#dfn-language-tagged-string">language tag</a> is preceded by a '<code>@</code>' (<span class="codepoint">U+0040</span>).
+          If there is no language tag, there may be a <a href="http://www.w3.org/TR/rdf11-concepts/#dfn-datatype-iri">datatype IRI</a>, preceeded by '<code>^^</code>' (<span class="codepoint">U+005E</span> <span class="codepoint">U+005E</span>). If there is no datatype IRI and no language tag, the datatype is <code>xsd:string</code>.

+        <p>
+          <a href="http://www.w3.org/TR/rdf11-concepts/#dfn-blank-node">RDF blank nodes</a> in N-Quads are expressed as <code>_:</code> followed by a blank node label which is a series of name characters.
+          The characters in the label are built upon <a href="#grammar-production-PN_CHARS_BASE">PN_CHARS_BASE</a>, liberalized as follows:
+        </p>
+        <ul>
+          <li>The characters <code>_</code> and digits may appear anywhere in a blank node label.</li>

+        </ul>
+        <p>
+          A fresh RDF blank node is allocated for each unique blank node label in a document.
+          Repeated use of the same blank node label identifies the same RDF blank node.

+        <p>The Internet Media Type / MIME Type for N-Quads is "application/n-quads".</p>
+        <p>It is recommended that N-Quads files have the extension ".nq" (all lowercase) on all platforms.</p>
+
+        <p>It is recommended that N-Quads files stored on Macintosh HFS file systems be given a file type of "TEXT".</p>

+
+          <dt>Encoding considerations:</dt>
+          <dd>The syntax of N-Quads is expressed over code points in Unicode [<cite><a class="bibref" href="#bib-UNICODE">UNICODE</a></cite>]. The encoding is always UTF-8 [<cite><a class="bibref" href="#bib-UTF-8">UTF-8</a></cite>].</dd>
+          <dd>Unicode code points may also be expressed using an \uXXXX (U+0 to U+FFFF) or \UXXXXXXXX syntax (for U+10000 onwards) where X is a hexadecimal digit [0-9A-F]</dd>
+          <dt>Security considerations:</dt>
+          <dd>N-Quads is a general-purpose assertion language; applications may evaluate given data to infer more assertions or to dereference IRIs, invoking the security considerations of the scheme for that IRI. Note in particular, the privacy issues in [<cite><a class="bibref" href="#bib-RFC3023">RFC3023</a></cite>] section 10 for HTTP IRIs. Data obtained from an inaccurate or malicious data source may lead to inaccurate or misleading conclusions, as well as the dereferencing of unintended IRIs. Care must be taken to align the trust in consulted resources with the sensitivity of the intended use of the data; inferences of potential medical treatments would likely require different trust than inferences for trip planning.</dd>
+
+          <dd>N-Quads is used to express arbitrary application data; security considerations will vary by domain of use. Security tools and protocols applicable to text (e.g. PGP encryption, MD5 sum validation, password-protected compression) may also be used on N-Quads documents. Security/privacy protocols must be imposed which reflect the sensitivity of the embedded information.</dd>
+          <dd>N-Quads can express data which is presented to the user, for example, RDF Schema labels. Application rendering strings retrieved from untrusted N-Quads documents must ensure that malignant strings may not be used to mislead the reader. The security considerations in the media type registration for XML ([<cite><a class="bibref" href="#bib-RFC3023">RFC3023</a></cite>] section 10) provide additional guidance around the expression of arbitrary data and markup.</dd>
+          <dd>N-Quads uses IRIs as term identifiers. Applications interpreting data expressed in N-Quads should address the security issues of
+      <a class="norm" href="http://www.ietf.org/rfc/rfc3987.txt">Internationalized Resource Identifiers (IRIs)</a> [<cite><a class="bibref" href="#bib-RFC3987">RFC3987</a></cite>] Section 8, as well as

+
+          <dd>Multiple IRIs may have the same appearance. Characters in different scripts may 
+    look similar (a Cyrillic "о" may appear similar to a Latin "o"). A character followed 
+    by combining characters may have the same visual representation as another character 
+    (LATIN SMALL LETTER E followed by COMBINING ACUTE ACCENT has the same visual representation 
+    as LATIN SMALL LETTER E WITH ACUTE).
+    <!-- (<code>foo:resum&#40751;code> and <code>f&#1086;&#1086;:resume&#769;</code>)-->
+    Any person or application that is writing or interpreting data in Turtle must take care to use the IRI that matches the intended semantics, and avoid IRIs that make look similar.
+    Further information about matching of similar characters can be found 
+    in <a class="inform" href="http://www.unicode.org/reports/tr36/">Unicode Security 
+    Considerations</a> [<cite><a class="bibref" href="#bib-UNICODE-SECURITY">UNICODE-SECURITY</a></cite>] and
