<section1 topic='Introduction' anchor='intro'>
|
|
<p>When interacting with an user, like replying to some comments or adding photo tags, this remote user has no way to get notifications of what happen about him. This specification defines a method for managing such notifications.</p>
|
|
</section1>
|
|
|
|
<section1 topic='Requirements' anchor='requirements'>
|
|
<p>The user who will receive notifications MUST:</p>
|
|
<ul>
|
|
<li>Create a "urn:xmpp:inbox" PEP node on his JID.</li>
|
|
<li>Configure the "urn:xmpp:inbox" PEP node with "pubsub#access_model" to "whitelist" and "pubsub#publish_model" to "open".</li>
|
|
</ul>
|
|
<p>In order to get incoming notifications in real-time, the client MAY advertise support for "urn:xmpp:inbox+notify" in its &xep0115; data.</p>
|
|
<p>Clients that provide notifications inbox support MAY request all the "urn:xmpp:inbox" node items on the user's PEP service.</p>
|
|

|
<section1 topic='Protocol' anchor='protocol'>
|
|
<section2 topic='Notification types' anchor='notif_types'>
|

<p>If the event to notify is listed in the following array, the client MUST consider using the defined event type:</p>

<section2 topic='Publishing a notification' anchor='notif_publish'>
|
|
<p>If Romeo wants to notify all the users who posted a comment in a comment node, his client MUST send a payload to every user's PEP node.</p>
|
|
<p>The notification type is stored in the "title" attribute of the "link" element, also containing the URI ("href" attribute) to the target item. The notification text content is stored in the "content" element.</p>

<section1 topic='Security Considerations' anchor='security'>
|
|
<p>The client SHOULD check that the author informations (provided in the "author" element) are valid, by checking that the "publisher" item attribute value matches the "uri" element value. If there is a difference, the notification MIGHT NOT be displayed, and the client SHOULD remove it (see the <link url='#notif_remove'>Removing a notification</link> section of this document).</p>
