I can't make 1/24 nor 1/25.

How about 1/22 at 5:00 PM EST, or 1/23 at noon EST?

Is the purpose of this solely to enable a device to turn on or off 
enunciators (e.g., voice mail or email icon on main phone screen)? 
More specifically, is the intent that this is primarily intended as 
input to a device's main UI, as opposed to a specific application on 
a device (such as an email client)?

Is the purpose of this intended to be limited to such wake-ups?  If 
the intent is to exclude more detailed information (such as the 
sender address, subject text, attachment and size information) then 
we have a very simple protocol with limited security needs.  Such a 
protocol can probably be mandatory to implement, but provides only a 
subset of the desired cool capabilities.  (This is often a good thing 
to start with.)

The differences between each of the three categories involve the 
level of detail supplied (and hence the security requirements), 
complexity, and user control.

5pm EST is 22:00 for me in UTC, and 23:00 for most of Europe. I can 
do this, but I'm not sure you'd get useful input.

Noon is 5pm for UTC, 6pm for CET. I can do this.

Good question - I've heard this discussed as part of the notification 
area of Lemonade, and I'd got it into my head that we were talking 
about a simple icon or blinking light - very much a boolean 
indicator, rather than a numeric display.

Well, I'd really seen this as a protocol to avoid synchronizing - 
what various people have described as "true push". A "sync needed" 
protocol is really a lot simpler, and simple STATUS message packaging 
probably do for that and the MWI scenario very nicely.

I'd also state for the record that I don't think we need more than a 
STATUS response, but pushing content and detailed state out of band 
has been a consistent feature of many proposals.

I'm not so sure. I think the first two can be seen as the limits on a 
spectrum of machine-readable notifications, whereas machine 
readability isn't nearly so important when considering a 
user-directed alert.

Luckily, I also happen to think that user-alerts are essentially 
taken care of by Sieve, on delivery.

I use "Google Notifier" (which uses pull, not push notifications but  
we can take it as a real-life use case) to let me know when to check  
mail hosted by google.
	- It displays a coloured icon and a number when I have unread  
messages (number of unread msgs)
	- It displays the sender and the first 20 or so characters of the  
last four unread messages.
	- It displays how fresh the information is ("Checked 1 min ago")

Another use case is a calendar client that can be configured to look  
at your IMAP Inbox directly, and it wants to get notified when there  
are incoming iMIP messages rather than poll frequently (I guess the  
message ID would be nice to allow it to quickly download the whole  
message).

My opinion is that it would be good to get notifications working at  
all, before trying to build true-push synchronization.  I'd prefer to  
have synchronization be out-of-scope for notification work.

Interesting -- I hadn't thought about machine readability as an 
aspect of this -- I'd been assuming that all notifications were 
machine-readable and would be interpreted by the client or device, 
and then acted on in some way (ignore, silently update cache, defer, 
download in background, display something to user, etc.)  So I was 
thinking of user-directed as user-specified criteria, that is, the 
"directed" meaning "directed by" instead of "directed at" (the user). 
For notifications directed at the user and not intended for 
processing by the device or client, does lemonade need to be involved 
at all?

For user-readable alerts, I'd agree.  For machine-readable, I'd want 
to be sure it is covered properly.

Hi,

I wrote a draft describing how to extend the message-summary event
package (currently used for MWI) to do sieve notifications.  Until it
appears in the archive, it is here:

http://svn.resiprocate.org/rep/ietf-drafts/rohan/email-event/draft-mahy-sieve-notify-sip-00.html
http://svn.resiprocate.org/rep/ietf-drafts/rohan/email-event/draft-mahy-sieve-notify-sip-00.txt

btw: I do not have a real stake in this discussion.  As author of some
related technology I thought I would enumerate one way to do it.

thanks,
-rohan

I've been meaning to send this out more broadly after a bit of  
private comment: two quite different models for setting up event  
streams based on what's easier to authenticate -- the event stream  
"owner" (in this case the mailbox owner) or the stream recipient.  I  
hope it helps compare different approaches.

Lisa

---

The goal is to start (and stop) events flowing from an event source  
(in our case, an email server) to the event sink, frequently using a  
system with an explicit event relay.   Because there are often three  
parties required in an event flow , we have to pick some way for the  
three parties to coordinate.

The three parties are the event source (an email server), the event  
sink (a client, perhaps not an email client)  and an event relay.   
The event relay has many users thus it has addresses for each user  
and possibly also addresses for devices/clients.  Two kinds of  
application-layer explicit event relays are starting to be common:  
XMPP and SIP.  For the purposes of considering an event feed setup  
model, we do not want to be concerned about the mostly orthogonal  
issue of what protocol to use to talk to event relay.  So for now we  
assume that event relays have all features common to XMPP and SIP  
(addresses, pub/sub features, event stream aggregation).

Choosing between two event stream setup models requires assumptions  
about
	- what kind of authorization is easier or more important to provide
	- whether there are a lot of different event sink addressess
	- whether direct access to the event source is always/usually  
available (can be affected by whether the event source is publicly  
available)
	- whether event flows stop and start frequently, or can simply be  
turned on for a very long term

MODEL A.  SUBSCRIBE Chain

A-1 Description

In this model, when a user decides to get an email event flow to a  
particular device or piece of software, the user typically works with  
the event sink interface to indicate where to get the events from.   
Then a SUBSCRIBE message of some kind gets generated by the event  
sink, sent to the event relay and is handled by the event source.

A-2 Authorization issue

The authorization problem here is to determine if the address that  
the SUBSCRIBE message comes from is permitted to receive these  
events.  In the case of a publicly-subscribable resource this problem  
disappears.  In many email use cases, only a small number of event  
sink addresses will be authorized to receive event notifications --  
perhaps the event source (the email server) can simply be configured  
with a short allowed list of event recipients that doesn't change  
often (e.g. my personal IM address, my work address, and the one used  
by my phone provided by my phone service provider).

Some SUBSCRIBE systems have the ability to provide a PENDING response  
to a subscription.  This is used when an out-of-band mechanism is  
initiated to authorize the subscribing address.  In an email event  
source use case, one obvious out-of-band mechanism is for the email  
server to create an email with a link saying "Click here to authorize  
this subscription".

It's also possible to use a mechanism like URLAUTH to prove  
authorization -- in this approach, the subscriber provides a URL that  
has a secret token in it authorizing the subscription.  It's possible  
that this would authorize the subscribing address for future  
subscriptions as well, or only for a limited period.

A-3 Drawbacks:
    a)  Only some notification protocols support SUBSCRIBE semantics.

    b)  Complicated filters and event types (to support use cases  
like "Alert me on event type 'email arrives' if it is from my boss,  
has my full email address or the address of the developer list on the  
to line, and the subject does not begin with 'FUNNY'..." )  might  
need a little extra work.  Both SIP and XMPP subscriptions can be  
extended in such a way that existing notification relays would pass  
on a filter specification in whatever language/format most  
appropriate for email.  It might even be possible to send SIEVE  
conditionals in the body of the SUBSCRIBE message.  XMPP has  
notification nodes in XEP-0060 and notification filters in XEP-0163.

A-4 Advantages
    b) Allows for frequent starting and stopping of subscriptions,  
possibly an efficiency/scaling concern


MODEL B. Sender RULES

B-1 Description

In this model, the user typically works with the event source in  
order to configure it to send events to a given set of addresses.   
For example, the user might have access to a Web interface to an  
email server where it can say "Send new message notifications to  
xmpp://lisa@psg.com" or someday use MANAGESIEVE.

B-2 Authorization issue

The authorization problem here is to determine if the user creating  
the sending rule is authorized to send an event stream to the  
receiving address.  If anybody can send to the receiving address  
(e.g. email) then it's publicly addressable and the problem  
disappears.  Many kinds of addresses are publicly addressable and use  
whitelisting together with asking permission ("do you wish to allow  
messages from this source in the future").

B-3 Drawbacks:
    a) Only some event sources support RULE systems.  We are building  
SIEVE for email clients and servers but it may be harder to  
generalize this beyond email clients and servers.  Even sticking  
strictly the proposed scope of email server sources, we have to  
consider whether a client such as a calendar client (subscribing for  
IMIP messages) or a time-management dashboard (subscribes to "unread"  
counts but doesn't otherwise read email) are going to be able to  
implement SIEVE, authenticate to mail servers etc.

    b) If sender rules are setup through Web interfaces, users are  
definitely not going to turn them on and off frequently.

    c) Failure feedback: how does the event source let the user know  
that some address keeps bouncing?

Apologies to Randy, but it looks like the 25th is the day.

Also, apologies to the list for sending in HTML.  It's the only way I
know of sending the URL's without them line breaking.

I'm too lazy to try to get a notifications Jabber room setup, so we will
use the lemonade room:

Server: jabber.ietf.org
Room: lemonade
Logs: <http://www.ietf.org/meetings/ietf-logs/lemonade/>

Time and Date:
10:00am Eastern Time, 25 January 2007
<http://www.timeanddate.com/worldclock/fixedtime.html?month=3D1&day=3D25&=
yea
r=3D2007&hour=3D10&min=3D0&sec=3D0&p1=3D43>

Agenda:
Discuss goals and scope
