+<p>ARQ supports sorting results in a query. Users are able to specify
+an expression that can be a function (built-in function, custom
+function, or a variable).</p>
+<p>By default, results are sorted using the default behavior provided
+by the JVM. If you have the following query.</p>
+<div class="codehilite"><pre><span class="n">SELECT</span> ?<span class="n">label</span> <span class="n">WHERE</span> <span class="p">{</span>
+ <span class="n">VALUES</span> ?<span class="n">label</span> <span class="p">{</span> "<span class="n">tsahurin</span> <span class="n">kieli</span>"<span class="p">@</span><span class="n">fi</span> "<span class="n">t</span>š<span class="n">ekin</span> <span class="n">kieli</span>"<span class="p">@</span><span class="n">fi</span> "<span class="n">tulun</span> <span class="n">kieli</span>"<span class="p">@</span><span class="n">fi</span> "<span class="n">t</span>ö<span class="n">yht</span>ö<span class="n">hyypp</span>ä"<span class="p">@</span><span class="n">fi</span> <span class="p">}</span>
+<span class="p">}</span>
+<span class="n">ORDER</span> <span class="n">BY</span> ?<span class="n">label</span>
+</pre></div>
+
+
+<p>The results will be returned exactly in the following order.</p>
+<ul>
+<li>"töyhtöhyyppä"@fi</li>
+<li>"tsahurin kieli"@fi</li>
+<li>"tšekin kieli"@fi</li>
+<li>"tulun kieli"@fi</li>
+</ul>
+<p>However, in Finnish the expected order is as follows.</p>
+<ul>
+<li>"tsahurin kieli"@fi</li>
+<li>"tšekin kieli"@fi</li>
+<li>"tulun kieli"@fi</li>
+<li>"töyhtöhyyppä"@fi</li>
+</ul>
+<p>To specify the <a href="https://en.wikipedia.org/wiki/Collation">collation</a>
+used for sorting, we can use the ARQ <code>collation</code> function.</p>
+<div class="codehilite"><pre><span class="n">PREFIX</span> <span class="n">arq</span><span class="p">:</span> <span class="o"><</span><span class="n">http</span><span class="p">:</span><span class="o">//</span><span class="n">jena</span><span class="p">.</span><span class="n">apache</span><span class="p">.</span><span class="n">org</span><span class="o">/</span><span class="n">ARQ</span><span class="o">/</span><span class="k">function</span>#<span class="o">></span>
+<span class="n">SELECT</span> ?<span class="n">label</span> <span class="n">WHERE</span> <span class="p">{</span>
+ <span class="n">VALUES</span> ?<span class="n">label</span> <span class="p">{</span> "<span class="n">tsahurin</span> <span class="n">kieli</span>"<span class="p">@</span><span class="n">fi</span> "<span class="n">t</span>š<span class="n">ekin</span> <span class="n">kieli</span>"<span class="p">@</span><span class="n">fi</span> "<span class="n">tulun</span> <span class="n">kieli</span>"<span class="p">@</span><span class="n">fi</span> "<span class="n">t</span>ö<span class="n">yht</span>ö<span class="n">hyypp</span>ä"<span class="p">@</span><span class="n">fi</span> <span class="p">}</span>
+<span class="p">}</span>
+<span class="n">ORDER</span> <span class="n">BY</span> <span class="n">arq</span><span class="p">:</span><span class="n">collation</span><span class="p">(</span>"<span class="n">fi</span>"<span class="p">,</span> ?<span class="n">label</span><span class="p">)</span>
+</pre></div>
+
+
+<p>The function collation receives two parameters. The first is the desired
+collation, and the second is the function (which can be a variable, or
+another function).</p>
+<p>The collation used, will be the Finnish collation algorithm provided
+with the JVM. This is done through calls to methods in the <code>java.util.Locale</code>
+class and in the <code>java.text.Collator</code>, to retrieve a collator.</p>
+<p>If the desired collation is not available, or invalid, the JVM behavior is
+also adopted. It may return the default collator, but it may vary depending
+on the JVM vendor.</p>
+<p>Note that this function was released with Jena 3.4.0. Mixing locales may
+lead to undesired results. See JENA-1313 for more information about the
+implementation details.</p>
