<p>These characteristics map well to instant messaging systems such as those built using Jabber/XMPP technologies (e.g., permissions can be based on existing presence subscriptions as reflected in the XMPP roster or "buddy list"). Furthermore, the push nature of XMPP (especially as formalized in the &xep0163; profile of &xep0060; overcomes the problems of polling for updates via HTTP, which has caused scaling issues in existing microblogging services. Therefore this specification defines a method for microblogging over XMPP, building on the existing method for transporting Atom syndication data &rfc4287; over XMPP as described in &atomsub;. These XMPP-based methods are complementary to HTTP-based methods, and can provide an XMPP interface to existing microblogging services (which may also be accessible via HTTP, Short Message Service (SMS), and other message transports).</p>

<p>It's also possible for Benvolio to add his own thougths to the repost. To do this he SHOULD wrap the original content in the "xhtml:blockquote" element and after it add his own content. Also, the client MAY post reply without quotation to the original thread to inform users about the repost.</p>

<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 <link /> element. The "href" and "rel" attributes MUST be added; the "title", "type" and "length" ones MIGHT be added.</p>
|
<p>It's often handy to specify categories (or tags) to a post to make it easier to find it or to structure a blog. It's possible by adding "atom:category" element to the entry (it can be blog or replies entry).</p>

|

<p>Romeo may want to publish some informations about his microblog, such as its title, an alternate web-version URI or the last time it was updated.</p>
|
<p>In order to provide some statistical information, to represent the blogs other ways than XMPP (i.e. in web or NNTP), we will need other entities called "Aggregators".</p>
|
||||||
<p>Romeo's client MAY publish these informations once he defined them. If so, his client MUST send them to the "urn:xmpp:microblog:0:informations" node, containing one only item, with the ID set to "0".</p>
|
<p>You can think of aggregators like about search engines in the web: they gather information from the whole web and then represent it suitable ways. The same is true here: Aggregators just subscibe to many entities and then they can build a database to make queries and show appropriate information according to these queries. Also they can be used to represent information in web or other networks.</p>
|
||||||
<example caption="Publishing microblog informations"><![CDATA[
|
<p>Unlike web search engines, an XMPP aggregator does not need to gather information by downloading it frequently to check if something was changed. Instead, it can listen to pubsub events and make its database up-to-date based on this information.</p>
|
||||||
<iq from='romeo@montague.lit/pc'
|
<p>Aggregators can be started by different people with different aims. It can be aggregator which devoted to the concrete blog service provider which will be subscribed only to its own users, or it can be a global search engine which tries to subscribe to most of users or to aggregate the feeds of other aggregators.</p>

<section2 topic="Pubsub Item ID vs. Atom Entry id" anchor="pubsub_id_vs_atom_id">
|
||||||
type='set'>
|
<p>There are two different things that carry a similar sense: the XMPP pubsub Item ID and the "atom:id" element. This section is devoted to make a separation between them.</p>
|
||||||
<pubsub xmlns='http://jabber.org/protocol/pubsub'>
|
<p>The pubsub Item ID MUST be used when linking to an entry with an XMPP channel (i.e. by including it in the URI with the "xmpp" schema). the Atom entry ID MUST be built according to &rfc4287; and used in aggregators with the aim of revealing of post duplicates, reposts, mentions, syndications, etc.</p>
|
||||||
<publish node='urn:xmpp:microblog:0:informations'>
|
<p>Note that the rules of comparing, building and security notes for "atom:id" are listed in the &rfc4287;.</p>

<p>When replying to a comment, it is RECOMMENDED the user's client send a notification to the people who commented on the comments node, as defined in a forthcoming specification currently located at <<link url='http://xmpp.org/extensions/inbox/notification-inbox.html'>http://xmpp.org/extensions/inbox/notification-inbox.html</link>>.</p>
|
|
||||||
<p>When quoting an user's name (e.g., by using @user tag), it is also RECOMMENDED to send a similar notification.</p>

<p>Depending on service policies and the value of the "pubsub#include_body" node configuration option, microblogging notifications SHOULD include a message <body/> element for backwards-compatibility with Jabber clients that are not pubsub-capable. It is RECOMMENDED for the XML character value of the <body/> element to be the same as that of the <content/> child of the Atom <entry/>.</p>
