<section2 topic='Location' anchor='location'>
<p>A person's microblog SHOULD be located at a personal eventing (PEP) node whose name is "urn:xmpp:microblog:0" but MAY be located at a generic publish-subscribe node that is not attached to a user's IM account. For instance, if the Shakespearean character Romeo has a JabberID of &lt;romeo@montague.lit&gt; then his microblog would be located at that JID with a node of "urn:xmpp:microblog:0". Outside of native XMPP systems, this node can be referred to as the following XMPP URI (the ":" character from the namespace URN is percent-encoded in the query component; see &rfc5122; and &rfc3986;).</p>
<code><![CDATA[
xmpp:romeo@montague.lit?;node=urn%3Axmpp%3Atmp%3Amicroblog
xmpp:romeo@montague.lit?;node=urn%3Axmpp%3Amicroblog%3A0
]]></code>
<p>Naturally, this node can be discovered by contacting romeo@montague.lit directly using &xep0030;.</p>

<p>Assuming that Romeo has also shared presence with Benvolio and has advertised support for "urn:xmpp:microblog:0+notify", he will receive the reply that Benvolio sent.</p>
</section2>
<section2 topic='Repeating a Post' anchor='repeat'>
<p>When Benvolio wants to repeat a Romeo's post, his client publishes the same post under a different name. But to be able to track the repeated post original author, Benvolio's client MAY use two specific &lt;author /&gt; child nodes, &lt;name /&gt; and &lt;uri /&gt;, containing, respectively, the name of the original post author, and his XMPP URI (JID).</p>
<p>If a comments link is present (see the <link url='#comments_node'>Comments node</link> section of this document), the client SHOULD repeat it to keep the same discussion about the post.</p>

<p>Thus, a different author JID value lets the client know the microblog item has been repeated from another one.</p>
</section2>
<section2 topic='Attaching files to a Post' anchor='attach'>
<p>Romeo might want to attach some files, such as pictures of his last vacations, or documents he wants to share. For each file to publish, Romeo's client MUST add a &lt;link /&gt; element. The "href" and "rel" attributes MUST be added; the "title", "type" and "length" ones MIGHT be added.</p>

<p>If client can generate some thumbnails images of the attached file (for pictures, videos or documents), it MAY create one or more &lt;link /&gt; sub-elements to the parent file &lt;link /&gt; element. It MUST set "xmlns" attribute to "urn:xmpp:microblog:0"; "rel" attribute to "self"; "title" attribute to "thumb"; "href" to the path of the thumbnail image. It SHOULD also have a "type" attribute specifying the thumbnail file MIME type.</p>

<p>Juliet and Benvolio may want to discuss about latest Romeo's post. Romeo's client MIGHT add a <link /> element to the PubSub item. The element MUST have "rel", "title" and "href" attributes, where "rel" MUST have the "related" value; "title" MUST have the "comments" value; "href" MUST be an XMPP URI (see &rfc5122; and &rfc3986;).</p>
<section2 topic='Comments node' anchor='comments_node'>
<p>We assume Romeo's client first created a comments node (named "urn:xmpp:microblog:0:comments:hash", where "hash" is a client-side generated random hash), with defaults "pubsub#access_model" and "pubsub#publish_model" privacy settings (see &xep0060; for node creation and configuration).</p>
