A Pubsub Social Feed can be located on any Pubsub node on the XMPP network. Some specific use cases, such as the personal eventing (PEP) node Microblog is defined in the Profiles section.

The publication of a Post consist of a valid &rfc4287; entry embeded in a &xep0060; item.

The post content itself can be either text (content element without "type" attribute or with "type" attribute with "text" value) or XHTML ("content" element "type" attribute with "xhtml" value). If Romeo publishes XHTML content, his client MUST publish two "content" elements: a text one, and a XHTML one. For XHTML publishing, see &xep0060;.

Note: The "title" element is required to be included in an "atom:entry" element according to &rfc4287;. An implementation MAY provide also "atom:summary" and/or "atom:content" elements too if it needs.

Because Juliet is subscribed to some Romeo's family Pubsub service nodes. Romeo's XMPP server will send a Pubsub notification to Juliet. The notification can include an XMPP message body for backwards-compatibility with Jabber clients that are not pubsub-capable (see Message Body ).

Note: these alternate links were not posted by the original client because some clients can't compute them themselves. These things SHOULD be inserted at server side though.

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.

Note: The post can be a reply to more than the only one another.

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.

Thus, a different author JID value lets the client know the item has been repeated from another one.

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.

This profile is specified by the Pubsub type "urn:xmpp:pubsub-social-feed:0" and define a generic Pubsub Social Feed that can be hosted on any Pubsub service node or &xep0163; node.

Those restrictions MUST be used by all the other profiles defined bellow and in other XEPs based on Pubsub Social Feed.

This profile is defined by the Pubsub type "urn:xmpp:microblog:0" as defined in &xep0277; and MUST be created and configured under the PEP "urn:xmpp:microblog:0" node.

This profile is defined by the Pubsub type "urn:xmpp:pubsub-social-gallery:0" and can be hosted on any Pubsub service.

All the items published in a gallery node MUST only have at least one attached picture. This picture MUST be of type "enclosure" as specified in &rfc4287;.
