<section1 topic='Introduction' anchor='intro'>
|
|
<p>It is sometimes useful, while reading some conversations, to be
|
|
reminded about it at some point in the future. This specification
|
|
proposes a mechanism to allow clients to set up such reminders.</p>

<dd>
|
|
An automatically generated message addressed to an entity sent
|
|
at a given time. Its goal is to remind the creating entity
|
|
about something.

<p>This protocol requires handling of dates and times, as such it conforms to &xep0082;.</p>

<section1 topic='Discovering support' anchor='disco'>
|
|
<p>An entity may wish to discover if a service supports the Reminders feature; in order to do so, it sends a service discovery information query to the server..</p>
|
|
<example caption='Client requests information about a server'><![CDATA[
|
|
<iq from='juliet@capulet.net/balcony'
|
|
id='disco1'
|
|
to='capulet.net'
|
|
type='get'>
|
|
<query xmlns='http://jabber.org/protocol/disco#info'/>
|
|
</iq>]]></example>
|
|
<p>If the server supports the Reminders feature, it MUST specify the
|
|
'urn:xmpp:reminders:0' feature in its service discovery information
|
|
features as specified in &xep0030;</p>
|
|
<example caption='Server advertises support for reminders'><![CDATA[

|
<section1 topic='Use Cases' anchor='usecases'>
|
|
<p>For end users, this provides a way to be reminded about stuff
|
|
while being in a conversation, without the need to leave it and go
|
|
to some calendar application or similar and create a full event
|
|
there. By setting a reminder, a user will be notified by the server
|
|
at whatever given time the reminder is created with and with
|
|
whatever the description was set for such a reminder.</p>
|
|
<section2 topic='Creating a reminder' anchor='creating'>
|
|
<p>A user wants to create a new reminder. For creating a
|
|
reminder, an entity MUST send an IQ stanza with the 'type'
|
|
attribute with a value of "set" and a direct <reminder/>
|
|
child qualified by the "urn:xmpp:reminders:0" namespace.</p>
|
|
<example caption='User creates a new reminder'><![CDATA[
|

<text xml:lang='en'>Please go sleep before it's too late</text>

|
</reminder>
|
|
</iq>]]></example>
|
|
<p>Whenever the reminder's data sent by a client is not complete or
|
|
in an invalid format, the server MUST send an error stanza of type
|
|
'modify' and a 'bad-request' condition.</p>
|
|
<example caption='Server sends a bad-request error response'><![CDATA[

<p>In the event of a client trying to set a reminder in the

past, the server MUST send an error stanza of type 'modify' and

a 'gone' condition.</p>

<section2 topic='Server sends a reminder' anchor='send'>
|
|
<p>Whenever the time for a reminder arrives, the server MUST send
|
|
a message with the reminder to the creating entity.</p>

<section2 topic='Client cancels a reminder' anchor='cancel'>
|
|
<p>There may be the case where a user wants to cancel an already

set reminder. To do so, the client MUST send an IQ stanza of

type 'set' with a 'reminder' child containing the 'id' attribute
|
|
of the reminder to be deleted, without any additional child.</p>
