Social features in XMPP were historically built on the &xep0277; specifications. However, in practice, Microblogging was not clearly defined in more common cases such as on generic Pubsub nodes and it was not easy to differentiate social nodes from the other ones. The current XEP defines a more generic way of handling Social Feeds on XMPP by declaring a secific pubsub#type for those Pubsub nodes and by keeping &xep0277; as a subset of it.

It's possible to insert some rich content in the post or comment. It can be some text formatting, images, etc. Only "xhtml" content type is supported for the moment by this document but possibly it will be extended later. Also, it is RECOMMENDED for the client to restrict XHTML content to the XHTML-IM subset (&xep0071;).

Anyone can publish a post in reply to Romeo's post. Here we assume that a reply comes from Benvolio.

Note: Inclusion of the "thr:in-reply-to" element defined in &rfc4685; indicates the post to which the user is replying. This reply includes two such elements (one pointing to the HTTP URL for the post and the other pointing to the XMPP URI for the post.

Assuming that Romeo has also subscribed to the same node he will receive the reply that Benvolio sent.

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 specific "atom:author" child node, "atom:name" and "atom:uri", containing, respectively, the name of the original post author, and his XMPP URI (JID).

The client SHOULD also put an "atom:link" element with "rel" attribute set to "via" and point it to the original post.

Depending on service policies and the value of the "pubsub#include_body" node configuration option, PubSub Social Feed notifications SHOULD include a message "body" element for backwards-compatibility with Jabber clients that are not pubsub-capable.

Juliet may want to know which places are Romeo's notices related to. That's why Romeo's client MAY geotag microblog entries, using the &xep0080; protocol for storing geolocation information.

Romeo's client MUST create a "geoloc" element, with the &xep0080; reference namespace: "http://jabber.org/protocol/geoloc".
