<section1 topic='Introduction' anchor='intro'>
|
|
<p>When initially run, a messaging client typically shows some list of contacts and chatrooms, and whether any new
|
|
messages are present in each.</p>
|
|
<p>The current mechanism for achieving this UX involves a complete synchronization of the server-side archive, and is both
|
|
time-consuming and bandwidth-intensive. This specification proposes a solution to directly obtain such data from
|
|
the server.</p>
|
|
<p>Moreover, the information gathered by the server to support this can be used in support of mobile push notifications.</p>
|
|
<section2 topic="Terminology">
|
|
<p>Nomenclature used for instant messages versus ancillary messages will need to be adjusted to make it consistent
|
|
with &xep0422; et al.</p>

<p>Support for this protocol is advertised by the Service Discovery protocol defined in &xep0030; using a feature

<section2 topic="The Inbox">
|
|
<p>The Inbox consists semantically of a list of conversations in order of last activity. Each conversation is
|
|
identified by a jid - for group chats this would be the chatroom, and for individual contacts this would be their
|
|
bare jid.</p>
|
|
<p>Each Inbox entry includes a count of messages considered new, the last MAM stanza-id relating to this conversation,
|
|
and the last MAM result for this conversation, as defined by &xep0313;. In addition, a client-controlled boolean
|
|
marker can be used to indicate a manual "set unread" state.</p>
|
|
<p>Finding more messages from this conversation can be achieved via a MAM query using <tt>with</tt> to specify the
|
|
conversation required.</p>
|
|

|
<section1 topic="Protocol Elements">
|
|
<section2 topic="Querying">
|
|
<p>An &IQ; of type "get" is used, containing a single element <tt><inbox/></tt>, containing an optional RSM
|
|
filter as specified by &xep0059;. This will typically be sent only to the user's own bare jid. The server
|
|
responds with a sequence of &MESSAGE; stanzas, each containing an <tt><entry/></tt> element qualified by the
|
|
<tt>&ns;</tt> namespace with a number of attributes:</p>
|
|
<ul>
|
|
<li><tt>jid</tt> - contains the Jid of the conversation for this entry.</li>
|
|
<li><tt>unread</tt> - contains a count of messages which are deemed to be unread by the server.</li>
|
|
<li><tt>marked</tt> - a boolean indicating that a client has explicitly marked the conversation for some reason.</li>
|
|
</ul>
|
|
<p>The <tt><entry/></tt> element contains the latest instant message, if any, which is encapsulated as a
|
|
<tt><result/></tt> element as defined by &xep0313;. This contains collated fastenings if supported by the
|
|
server.</p>
|
|
<p>After all entries required have been returned, the server then responds with an &IQ; result containing a
|
|
<tt><fin/></tt> element qualified by <tt>&ns;</tt>. This contains the RSM data, a total count of conversation
|
|
entries within the inbox, a count of conversations with unread messages, and a total count of unread messages.</p>
|
|
<p>Any counter of unread SHOULD be accurate, however client implementors please note that due to heuristics
|
|
involved and other issues these counters can be inaccurate at times.</p>
|
|
</section2>
|
|
<section2 topic="Marking">
|
|
<p>A client MAY at any time set a conversation as marked by sending an &IQ; of type "set" containing something or
|
|
other. This causes the server to set the "marked" flag on a conversation. A client SHOULD display a marked
|
|
conversation in the same way as an unread conversation, and explicitly removed the marked flag when the
|
|
conversation is considered re-read.</p>
|
|
<p>Removing a marked flag, even when the conversation is not currently marked, causes the unread counter for that
|
|
conversation to be set to zero.</p>
|
|
</section2>
|
|
</section1>
|
|
|
|
<section1 topic="Unread Messages">
|
|
<p>Servers MUST track which instant messages sent to clients remain unread.</p>
|
|
<ul>
|
|
<li>An instant message is always read if it is followed by an instant message which is read.</li>
|
|
<li>An instant message always starts unread.</li>
|
|
<li>A Chat Marker (see &xep0333;) of "displayed" or "acknowledged" causes the message to be read (and also causes
|
|
all prior messages to be read by implication).</li>
|
|
<li>A Message Receipt (see &xep0184;) does not cause messages to be considered unread. Perhaps it should?</li>
|
|
<li>Unmarking a conversation always sets the unread counter to zero, and by implication sets all messages to be
|
|
read.</li>
|
|
</ul>

<section1 topic="Examples">
|
|
<p>Let us assume a user has only two contacts they have exchanges messages with, and a single chatroom. Asking for their inbox is simple:</p>
|
|
<example><![CDATA[
|
|
<iq type='get' id='iq_stanza_id'>
|
|
<inbox xmlns=']]>&ns;<![CDATA['/>
|
|
</iq>
|
|
]]></example>
|
|
<p>The server responds with a list of conversations:</p>
|
|
<example><![CDATA[
|
|
<message>
|
|
<entry xmlns=']]>&ns;<![CDATA[' unread='2' marked='false' jid='first_contact@example.net'>
|
|
<result xmlns='urn:xmpp:mam:2' queryid='iq_stanza_id' id='uuid-1'>
|
|
<forwarded xmlns='urn:xmpp:forward:0'>
|
|
<message xmlns='jabber:client' from='first_contact@example.net' to='user@example.org' type='chat'>
|
|
<body>Greetings from Alpha Centauri!</body>
|
|
</message>
|
|
</forwarded>
|
|
</result>
|
|
</entry>
|
|
</message>
|
|
]]></example>
|
|
<p>After the list of messages, the server completes its response with a the reply to the original IQ.</p>
|
|
<example><![CDATA[
|
|
<iq type='result' id='iq_stanza_id'>
|
|
<fin xmlns=']]>&ns;<![CDATA[' total='3' unread='1' all-unread='2'>
|
|
<!-- RSM -->
|
|
</fin>
|
|
]]></example>

<p>The author notes that this protocol is heavily based on the <tt>mod_inbox</tt> system of MongooseIM. In addition, Kevin Smith provided useful feedback which has shaped this specification.</p>
