   mez: If we have more time we can talk about Stephen's posting on 5.3.7
   ... also need to create an issue to track it
   ... reminder, the next meeting is Dec 19th
   ... issue 119 will be on that meeting
   ... Every active participant should have received WSC-XIT by Dec 19t
   ... anything on agenda bashing

Issue-116

   <Mez> [20]http://www.w3.org/2006/WSC/track/issues/116

   UNKNOWN_SPEAKER: should users be able to reconfigure primary chrome

   Hal: The results of the email discussion showed parts of my write up
   were either strongly disagreed with or in the document somewhere else
   ... there should be a one step way to get back to the original
   configuration
   ... no one really commented on that

   <Mez> If the user agent does permit this, it MUST provide a mechanism
   to easily reset the user agent to display the all the required
   indicators in primary chrome.

   hal: The would be the last sentence of 2B, so the agent permits
   reconfiguration

   Ian: I like providing a way to get back to the default state, if this
   is different than the default compliant state, this should be clear
   ... but where would this be in the interface?
   ... if it's deep in a dialog box, can we say that's easy?

   hal: I don't mind if it's in the options dialog, it just shouldn't be
   more than one button wherever it is

   stephen: If i click this reset, if I previously deleted a root CA,
   would it then be reinstalled?

   Hal: this is just for the indicators
   ... this spec says you must indicate security information in a specific
   way
   ... the discussion convinced me that browsers should ship with this
   configuration, but users should be able to change their primary chrome
   if they'd like, doesn't apply to trusted roots

   mez: in the final write up we should reference the spec it applies to

   Hal: This means what does it mean to normatively comply with our specs
   ... if users can change this, there should be an easy way for them to
   go back to the original configuration

   stephen: ok, this sounds like a good idea

   hal: if we have agreement in the requirement, I can draft something and
   figure out where to put it in the document

   ian: I like the idea in principle
   ... but my question comes in, the browser doesn't come in the shipped
   state the manufacturer intends, extensions installed by the user or
   instances distributed by an OEM, if we have a notion of a good state,
   is this state the configuration that was defined by the OEM or the
   state that was defined by the browser vendors?

   <stephenF> tricky but good question

   ian: if I want to get back to one state, and these two are different,
   what happens?

   Yngve: I'd like to point out in opera you can right click on the skin
   and choose customize to make changes to the appearance, you can then
   revert to a previous skin if you haven't changed that one

   Hal: Wouldn't a browser that complies with the WSC spec comply with it
   on all skins

   Yngve: you haven't changed the configuration and then you go back to
   another skin, you can change between them quickly

   <ifette> my question is still open re: what does it mean to go back?
   which state are they going back to...

   Hal: the intent here is to say a compliant implementation must do XYZ,
   so I thought, ok we don't want users to change that, but people didn't
   like that, so if we allow them to change something, it must be easy for
   users to get back to the mode that is specified by our spec

   <Mez> I think he's saying - it's compliant, not shipped, and not
   browser default

   <stephenF> "compliant" being a useful label seems to imply some kind of
   branding

   <jvkrey_home> sounds like a "panic button" :)

   hal: I realize there are dozens of changes you can make to a browser,
   but you should be able to revert to the original configuration that is
   compliant in respect to the relevant specs

   ian: Two cases, 1) the OEM ships the browser in a way that conforms to
   the specs
   ... but a question arises if the OEM ships it in a state where it isn't
   compliant
   ... what if you return to a compliant state that is different than the
   shipped state?

   <stephenF> presumably there'd also be enterprise-specific distros that
   could be +/- compliance

   PHB: few points, one of them is we might not be able to make a
   non-configurable primary display

   <ifette> +1

   PHB: so if i have a plugin that suppresses the authorized security
   indicator, but I do it to present a stronger security indicator, so I
   don't see why we would prohibit this

   hal: we dropped that aspect of the question

   ian: if there was a firefox shipped with secure letterhead that
   replaces the lock icon
   ... then what happens

   mez: how about if we have a button that does something, it's clear what
   it does
   ... we shouldn't have buttons that do one thing and state they do
   something else

   Hal: I'm just saying there's more than one way to be compliant

   mez: the plugin issue is a tough one

   <stephenF> how about instead of going "back"/"reset" we "move to"
   compliance (automagically)

   PHB: I think it comes down to suggesting a should, but people will
   demand more rope despite what we do

   hal: the use case I have in mind, someone calls and has a problem, and
   someone can say, go to this page, click here and tell me what's going
   on

   stephen: I think Ian's question is a good one, so what if instead of
   resetting to a previous state, it moves to to a compliant state,
   regardless of what the "original" state was

   mez: it sounds like this is something that could be turned into useful
   language
   ... but it seems like concrete language would be useful
   ... in a proposal for the spec

   hal: and I will take into account the discussion

   thanks, Ian

   <ifette> ACTION: hal to propose language for ISSUE-116 based on last
   sentence of 2b and the discussion in 12/12's meeting [recorded in
   [21]http://www.w3.org/2007/12/12-wsc-minutes.html#action01]

   <trackbot-ng> Created ACTION-358 - Propose language for ISSUE-116 based
   on last sentence of 2b and the discussion in 12/12's meeting [on Hal
   Lockhart - due 2007-12-19].

   jvkrey: Just thinking about the last use case, so someone reconfigured
   their browser and you want to know what's going on, so thinking about
   the browser lockdown mode and you disable all the plugins and only have
   the basics, then I was thinking hal's use case is a lot like browser
   lockdown

   hal: I'm not sure where the proposal for browser lockdown is, but I
   thought it was limited to a subset of sites?

   mez: I think once we have a concrete proposal we'll be able to see
   where the overlap is

   I'm on mute

   mez: anything else on issue 116

   <Mez> [22]http://www.w3.org/2006/WSC/track/issues/118

   mez: great, we have an action item for next steps, so now issue 118

ISSUE-118

   hal: this is one where I made a comment and the issue landed on me
   ... if there was a non-browser UI, we ought to have a consistent set of
   terms that refers to user actions across the interaction models
   ... i don't really use a cell phone browser, so I'm not sure what the
   user operations would be
   ... I'm also unsure of what the relevant user actions might be
   ... we need someone who's familiar with user actions on these different
   user agent

   mez: i also found it difficult to avoid only thinking about a user
   interacting with a desktop/laptop user agent
   ... i've been less conscientious of small interfaces, and have been
   relying on Luis to keep us honest
   ... also asked the nokia rep for a review

   Hal: I was thinking of going further and saying in general within this
   document, when we say X it means Y for browser interaction and Z on
   another user agent
   ... I don't see this being a huge piece of the document, just a few
   examples of the major ones

   mez: interesting that you want this in the beginning of the document
   ... I'm still wondering what section 3 is doing in the document and
   whether this might go there

   <Mez>
   [23]http://www.w3.org/2006/WSC/drafts/rec/rewrite.html#Conformance

   mez: it might be completely motivate by tlr and his concern with our
   spec might be used by other models
   ... if you haven't done your review, maybe you could take a first cut
   at a list
   ... which would give us an idea of the terms we need to come to terms
   with
   ... I'm ok with letting the issue rest until we get the reviews of Hal,
   Ericson and Nokia
   ... anything else on this one?

   <Mez> [24]http://www.w3.org/2006/WSC/track/issues/131

Issue-131, what about the language of executing outside the browser without
telling the user

   mez: comment by Ian is basically the browser must notify the user when
   trying to execute something outside the browser

   ian: I agree we want to prevent software being downloaded and run
   without the user's content, we also want to stop something from running
   within the browser without the user's consent, but how will the browser
   alert the user when something is running outside the browser without
   consent?
   ... but it's often the case that applications are running outside the
   browser as a result of the actions in the browser
   ... example of a browser with the abode plugin and a user reading a pdf
   in the browser
   ... would we show a dialog every time the user opens a pdf in the
   browser?
   ... second example of windows media player and playing a video

   <Mez>
   [25]http://www.w3.org/2006/WSC/drafts/rec/rewrite.html#techniques-robus
   tness

   <Mez> 3rd bullet

   ian: can we change this so it's just when the software is new, or only
   when the user isn't expecting something external to be running

   <stephenF> +1 to ian's concern

   phb: I think we need to distinguish between inside and outside the
   browser

   <Mez> "browser environment" not defined in spec right now - does it
   include plug ins?

   phb: just like java knows what's internal to java and what's outside
   the sandbox

   <Mez> ian's concern is I think only about the execute word, not the
   install word, yes?

   phb: so the browser should know that it can operate within this sandbox
   model, and inform the user when something goes outside the sandbox

   <ifette> mez, both

   <ifette> but mostly execute...

   <Mez> what's the example that motivates the install concern?

   <ifette> codecs

   phb: we need to define the line, then have verbage about what happens
   when something crosses the line

   <Mez> not familiar with codecs; link?

   <ifette> no good link to give you. Imagine though that you are trying
   to view a video, and media player tells you that you don't have the
   necessary codecs installed, and that it will download the DivX codec
   for you. Media player will hopefully warn you, but I have no idea if
   your browser will warn you (or even know that this is going on)

   going to adobe, there are different versions of what can be done given
   what you've opened -- so you could be running adobe with different
   privileges depending on the mode

   <ifette> no

   hal: aren't we only concerned when it's come from the net

   <Zakim> ifette, you wanted to say that the browser might actually might
   not know, if the active-x plugin just calls coinitializesecurity,
   starts up some new processes, does IPC etc, that

   ian: to hal, if we assume if it's already installed it's safe to run,
   no
   ... if active x is there, the majority of the installed options
   shouldn't be run from a browser

   <Mez> it's my understanding that Microsoft has said that the security
   model of ActiveX is not what they were hoping for, and they were not
   concentrating on it so much anymore.

   ian: second, the browser doesn't always know what's going on, the
   browser mostly starts the process, but it doesn't know exactly what's
   going on, and if it's forked to other processes
   ... so the browser might not know what's running outside the
   environment

   <Zakim> stephenF, you wanted to worry about bothering user so much they
   get trained to say "ok" always

   stephen: wondering if getting in the user's face is the right thing to
   do
   ... seems messy, which is a concern, not a suggestion

   hal: I see this issue as saying we see a bad case, can we define an
   implementable method for distinguishing between the good and bad case
   ... maybe the issue isn't inside of outside the browser, but did it or
   didn't it come from the browser
   ... don't want to say allow things you already don't
   ... what is the distinction we'd like to make and is it implementable

   <Mez> random restatement - Web user agents SHOULD inform the user and
   request consent when web content attempts to install software from the
   network.

   <stephenF> is "install" sufficiently well defined?

   hal: isn't auto adding a plugin just as bad?

   <jvkrey_home> browser extensions?

   yngve: I suspect what we're looking at is content that is not going to
   run in the configuration of the browser, but will be passed off to the
   OS, and out of the browser's ability to dictate policy and in this
   case, i'm including some plugins

   <Mez> Web user agents SHOULD inform the user and request consent when
   web content attempts to execute software that is not installed within
   the the browser environment. This consent SHOULD be retained and
   honored across sessions.

   <Zakim> asaldhan, you wanted to say that some plugins like the Adobe
   Flash do upgrades automatically. I am guessing that this is not a real
   concern.

   anil: point of observation, some plugins update automatically, so i'm
   guessing this isn't a concern for us, right?

   <ifette> probably for reader it reminds you...

   mez: they do it automatically, i know adobe whines, but ?

   <stephenF> "honored across sessions" might be tricky if the UA device
   changes network in the meantime

   anil: the new web 2.0 environment, auto updates

   mez: i don't know if upgrades are considered installed
   ... you might need to be worried

   hal: updating software of the user's system without giving the user
   anyway of getting involved with this, and there has been opposition to
   microsoft autoupdating

   <Mez> that's why the text refers to browser environment

   hal: i understand there might be a mode to say give me all the updates
   automatically
   ... but there should also be other modes

   <Zakim> ifette, you wanted to say we're ratholing

   ian: we're getting into a rathole on upgrading
   ... a lot of programs have upgraders that are always running
   ... it feels tangential to things running outside the browser

   yngve: i think what we're looking at in a download activated by content
   on a webpage
   ... it either tries to run outside the browser and in the os without
   the sandbox

   <Zakim> stephenF, you wanted to ask if the various browsers are
   sufficiently similar to have one definition of inside/outside

   stephen: if we can't have a definition across all browsers that works
   for defining inside and outside
   ... then where are we?
   ... we can only say something tangible if we can say it across browsers

   mez: so we should be able to say generally what should be executable

   <ifette> phb is breaking up

   <ifette> or move in your room

   <ifette> no

   <ifette> yes

   <ifette> kinda

   <ifette> are you on voip or cell? cause i cant understand you

   ( can't hear well enough to scribe)

   <Mez> right, don't sweat it maritza

   <ifette> meow? ;-)

   <PHB2> Its vonage

   <PHB2> Ah, thats the problem, Premiere had finished compressing my
   podcast and started uploading it.

   yngve: browsers currently have html and javascript, can't go outside,
   plugins can, and then you have content we don't know what to do with
   and we have to complete actions for it in outside applications, so we
   have content that needs to open in another application, and we have
   other content that we don't know how to handle -- the content the
   browser isn't sure how to handle could include the code that we
   wouldn't want to run automatically

   ian: I think we should remove 8.2.3.3

   mez: I'm not sure what the right process would be ...

   ian: create an action on the editors to remove

   <ifette> vote?

   mez: we should do a straw poll or something first to show consensus

   <ifette> remove / keep / reword?

   <ifette> vote at next meeting?

   mez: can we put that proposal in mail, you proposal for resolution is
   to remove the text
   ... if no one says anything i declare consensus, and we'd have to let
   it go through the holidays
   ... next next meeting

   <ifette> ACTION: ifette to follow up on ISSUE-131 thread to propose
   removing 8.3.2.3 in email [recorded in
   [26]http://www.w3.org/2007/12/12-wsc-minutes.html#action02]

   <trackbot-ng> Created ACTION-359 - Follow up on ISSUE-131 thread to
   propose removing 8.3.2.3 in email [on Ian Fette - due 2007-12-19].

   mez: if there isn't consensus we can do a straw poll

   hal: is the rational that we can't implement a way of separating the
   good and bad?

   ian: l'm saying in a lot of cases there's no way to know and a lot of
   browsers are doing this anyway, so any text around it would be more
   confusing than helpful

   hal: be sure to tie some rational to the action
   ... then depending on the expertise of the browser people we have, i'm
   ok

   mez: and we are looking at what browser's are currently doing for
   insights on our proposals

   <PHB2> That is why I proposed that we tell browser providers that they
   must determine a boundary

   ian: I think it's being done in that a browser won't take a tag and
   execute whatever's in it

   <PHB2> ... even though we cannot codify one for them in the spec

   ian: if someone can write this up, i could accept it, but in the
   absence of that, i think we should remove it
   ... i can't think of a way to write this that would work across
   browsers

   <PHB2> What does the boundary mean in a photo frame web browser

   mez: so someone who cares enough about retaining this should do that
   ... i don't know enough about what browsers actually do to write the
   definition

   <ifette> great

   <Mez> [27]http://www.w3.org/2006/WSC/track/actions/348

Action-348

   mez: stephen, you wanted to discuss this in a meeting before throwing
   it in the document

   stephen: two concrete things in this
   ... 1) got rid of the interaction cert idea, it's something that could
   go back in if there's a referenceable spec

   there was a definition of an attestation cert, which seems to overlap
   with the augmented cert idea, so i covered one of these and kept the
   augmented assurance idea

   scribe: also cleaned up the terminology
   ... aiming for consistency
   ... introduced a few abbreviations for terms, otherwise it's mostly
   just an editorial reorganization
   ... people should read through and do a diff

   mez: how to do a diff?

   stephen: read old and new and say which you prefer

   <ifette> cut and paste, save to files, and run diff...

   <Mez> do you get something useful?

   <ifette> depends ;-)

   yngve: difference about the trust root store?
   ... with attestation cert?

   <Mez> attested cert

   <Mez> attestation

   <Mez> of course no one is sure what that was supposed to mean, other
   than being a trust root

   <stephenF> i like the new one better:-)

   mez: so we'll give people time to review it
   ... stephen you should create an issue so we can track this
   ... so we've covered our agenda
   ... meeting next week

   <stephenF> there's an issue-113 already associated with that new text I
   think

   mez: then we're off for two weeks until 2008
