<p>Generally, each <code>-faults</code> function will return:</p>
<ol>
<li><code>nil</code> if no faults were found;</li>
<li>a sequence of fault objects if faults were found.</li>
</ol>
<p>Each fault object shall have the properties:</p>
<ol>
<li><code>:@context</code> whose value shall be the URL of a document specifying this vocabulary;</li>
<li><code>:type</code> whose value shall be <code>Fault</code>;</li>
<li><code>:severity</code> whose value shall be one of <code>minor</code>, <code>should</code>, <code>must</code> or <code>critical</code>;</li>
<li><code>:fault</code> whose value shall be a unique token representing the particular fault type;</li>
<li><code>:narrative</code> whose value shall be a natural language description of the fault type.</li>
</ol>
<p>Note that the reason for the <code>:fault</code> property is to be able to have a well known place, linked to from the @context URL, which allows narratives for each fault type to be served in as many natural languages as possible.</p>
<p>The idea further is that it should ultimately be possible to serialise a fault report as a document which in its own right conforms to the ActivityStreams spec.</p></div></div><div class="public anchor" id="var-activitystreams-context-uri"><h3>activitystreams-context-uri</h3><div class="usage"></div><div class="doc"><div class="markdown"><p>The URI of the context of an ActivityStreams object is expected to be this literal string.</p></div></div><div class="src-link"><a href="https://github.com/simon-brooke/dog-and-duck/blob/master/src/dog_and_duck/quack/picky.clj#L66">view source</a></div></div><div class="public anchor" id="var-context.3F"><h3>context?</h3><div class="usage"><code>(context? x)</code></div><div class="doc"><div class="markdown"><p>Returns <code>true</code> iff <code>x</code> quacks like an ActivityStreams context, else false.</p>
