Review and tweak agenda

AB: we will drop 3a. and 3c. since consensus for both of these was achieved via email after I posted the agenda. Will add a new agenda item about ECDSA. Are there any other change requests?

[ None ]

Announcements

AB: Please remember to register for the London F2F meeting June 9-11 (http://www.w3.org/2002/09/wbs/42538/WidgetsLondonJune2009/).
... the first voice conference of the Widgets Updates PAG is tentative scheduled for 13:00 Boston time on April 28 (http://lists.w3.org/Archives/Member/member-widgets-pag/2009Apr/0002.html) but Rigo Wenning hasn't yet confirmed that call.
... any other annoucements?

[ None ]

DigSig: comments by Mark

AB: on April 7 Mark submitted a relatively long list of comments (http://lists.w3.org/Archives/Public/public-webapps/2009AprJun/0070.html). Frederick and Marcos responded. If addressing any of these comments could benefit from some discussion today, we can allocate some time. Frederick, what's the status?

FH: I think we've reached consensus on most comments
... one issue is sig file
... I use "widget sig" rather than file
... I think both usages makes the most sense depending on context

MP: I agree most comments have been addressed
... but I still need to do some review

AB: let's drop this topic for today and take any followups on the mail list

DigSig: ECDSA and v1

AB: the ECDSA issue (captured reasonably well as Issue #81 http://www.w3.org/2008/webapps/track/issues/81) is still open. The latest ED does two related things: 1) it includes a note that requests feedback on ECDSA; 2) it also does NOT mandate ECDSA as one of the Signature Algorithms (and thus is a departure from latest WD of XML Signature 1.1). Today there was more discussion on this (http://lists.w3.org/Archives/Public/public-webapps/2009AprJun/0279.html). One q

FH: I think we need some text about it
... we cannot ignore it
... but we don't know what XML Sig 1.1 will decide
... using SHOULD may be a good way forward
... their risks with other algorightms so having an alternative to consider

<drogersuk> I agree with FJH

FH: I do agree MUST is too strong

DR: I agree with FH

<Marcos> +q

DR: failure to indicate a roadmap is not a good path to take

MC: I understand the concerns here
... if company X implements all of the algs except ECDSA and then they get a widget with ECDSA, there is a prob
... if SHOULD is used it will effectively make it required for the implementors
... it is expensive to implement to implement all of these algs
... perhaps for v1.1. we could add support for new algs
... would like some real proof there is real market demand for EC
... but without that evidence I don't support including it
... think it should either be MUST or not in the spec at all

DR: I understand your concerns Marcos
... need to try to forsee future issues with a limited set
... VF have made it clear they see it on their roadmap

FH: I understand the issues with switching suites
... we are following this in XML Sec WG
... we see a demand from US gov't at least

MC: OK, that's good information
... and in that case, perhaps it should be a MUST

FH: in XML Sec WG we are leaning toward a MUST but are considering various concerns
... think SHOULD would be a good indicator

AB: agree SHOULD would be a reasonable compromise
... we need to make it clear we want feedback from Implementors as well as Developers

MP: as I said on the list list, we think SHOULD is the best thing for now
... we can't use MUST at this point in time

MC: so let's go with SHOULD

AB: any additional comments?

[ None ]

<fjh> ECDSAwithSHA256

AB: propose a resolution: we will add ECDSA support as a SHOULD in the Widgets DigSig spec

<fjh> proposed resolution - add ECDSAwithSHA256 as should in widgets digsig

AB: any objections to my proposal?

[ None ]

RESOLUTION: we will add ECDSAwithSHA256 as a SHOULD in the Widgets DigSig spec

DigSig: getting ready for Last Call

AB: the basic question is what, specifically, needs to be done before this spec is "feature-complete" and hence for Last Call WD publication? Frederick responded to this yesterday (http://lists.w3.org/Archives/Public/public-webapps/2009AprJun/0261.html).

FH: one question is how to work this with Sig Properties spec
... not sure how to work this out as a Chair
... maybe we take this offline

AB: my gut feel is your WG should publish Sig Properties

FH: we probably want a single annoucement

<scribe> ACTION: Barstow work with Frederick re synching Signature Properties spec with Widgets DigSig spec [recorded in http://www.w3.org/2009/04/23-wam-minutes.html#action01]

<trackbot> Created ACTION-335 - Work with Frederick re synching Signature Properties spec with Widgets DigSig spec [on Arthur Barstow - due 2009-04-30].

<fjh> agree, xml security should publish signature properties. need to coordinate however.

AB: are we Feature Complete?

FH: I don't think the reqs are in synch with the Reqs doc

MC: the problem is the links point to the ED rather then what is /TR/
... we fix this when we publish these two docs in /TR/

AB: my recommendation is that when we publish the LCWD of DigSig we also at the same time publish a new Reqs doc
... are we done with functionality?

FH: I think yes

<mpriestl> +1

MC: yes

MP: yes

<darobin> +1 on top of mpriestl

RB: yes

MP: yes, just need to update ECDSA

<fjh> need to add ECDSA, possibly other minor editorial tweaks

AB: propose Resolution: the Widgets Digital Signature spec is Feature Complete; we will not add any new functionality
... any comments on that proposal?
... any objections?

[ None ]

DR: how would this affect schedule?

MC: I think this would put us ahead of scheudle

<fjh> please indicate the dates so that I can work with XML Security WG to publish Signature Properties

AB: we never agreed on specific dates but talked about LCWD in April and CR in June

RESOLUTION: the Widgets Digital Signature spec is Feature Complete; we will not add any new functionality

<fjh> so I will ask XML Security WG to agre to publish Signature Properties next week in XML Security WG call

<arve> we'll dial in anew

AB: I will start a new discussion on when to publish the LC of DigSig

<arve> we can't seem to dial in again

AB: that's it for DigSig for today. Thanks again FH for your great work here!

<mpriestl> + 1 on the thanks to fjh

<fjh> thanks, thanks Mark, Marcos

<fjh> as well

P&C: Dropping screenshot

AB: Marcos proposed (http://lists.w3.org/Archives/Public/public-webapps/2009AprJun/0197.html) dropping screenshot for v1 and has already added it to the V2 feature list (http://www.w3.org/2008/webapps/wiki/Widgets2_UC%26R). My recollection is all comments on this proposal were positive. Does anyone object to this proposal?

<MikeSmith> ArtB: try again now

AB: any objections to dropping screenshot?

RB: no

RESOLUTION: screenshot will not be in v1 (already added to the v2 feature list)

<MikeSmith> Marcos: is it a local phone problem? or a problem with Zakim?

<MikeSmith> arve: trying calling back in now, if you can

P&C: <access> element

AB: Robin made a short proposal several weeks ago (http://lists.w3.org/Archives/Public/public-webapps/2009JanMar/0943.html). There has been a little follow-up on the mail list but certainly no consensus on a solution. This is one of the major open issues that is blocking the publication of a new LCWD.

<MikeSmith> is P11 arve and Marcos ?

AB: Robin, where are we on this?

RB: I think we do have consensus, the issue is on the wording
... I will create some tighter wording
... but feature wise, the comments have been positive i.e. at the right level

AB: has your proposal been added to the ED?

RB: yes

AB: what's the next step?

RB: there really is no next step
... just need to fix the wording

AB: any comments?

MP: I support the current proposal
... there were some comments from BONDI

<mpriestl> * The User Agent's security policy MAY prevent network access by the Widget to an IRI that does belong to the set of target IRIs.

MP: my understanding of the current proposal is the above should be a MUST
... rather than the MAY

RB: I'm not sure I understand

MP: I'll need to go back and re-read it

AS: the sec policy may be more restrictive about IRI access then the P+C's access element

MP: yes, I agree with that
... and hence the BONDI statement is correct

AB: Arve, Marcos - do you have any comments about the access element?

MC: no, we still need to review it
... it appears to be a bit thin; may not cover all of the UCs we have in mind

AB: please, everyone, send all comments re <access> ASAP!
... anything else on this topic?
... what's the status of Thomas on this proposal?

RB: he may have some issues; not clear yet

P&C: Localization proposal from Marcos

AB: Marcos submitted a comprehensive localization proposal (http://dev.w3.org/cvsweb/2006/waf/widgets/i18n.html) several weeks ago. The amount of feedback has been very low yet this is a major open issue that is blocking the publication of a new LCWD. Currently, only me, Jere and Marcos have expressed their opinions on the various proposals thus I'd like to hear from other people.
... what do people think about this proposal from Marcos?

[ Silence ]

<mpriestl> (sorry I have to leave the call)

AB: one interpretation of silence is agreement with Marcos

AS: I haven't reviewed it yet

AB: we need feedback ASAP

AS: yes, I understand the priority

AB: what's the next step?

MC: I think we need more feedback

<scribe> ACTION: barstow seek comments from WG members on Marcos' L10N proposal [recorded in http://www.w3.org/2009/04/23-wam-minutes.html#action02]

<trackbot> Created ACTION-336 - Seek comments from WG members on Marcos' L10N proposal [on Arthur Barstow - due 2009-04-30].

AB: we can spend a lot of time on this today

MC: that would be good

AB: Marcos, lead us thru A1 and A2

MC: A1 has no support for sub-lang tags i.e. it does not support BCP47 and its lookup mechanism
... A2 supports BCP47 lookup
... A2 will reduce the amount of content that must be localized, particulary if there are multiple levels of sublangs

AB: so there is an efficiency tradeoff here, right?

MC: yes
... Jere and Josh both proposed A2 model
... note that A2 is already in the P+C spec

AB: any comments on A1 versus A2?

MC: I prefer A2

AB: I think we should give people one more week i.e. until April 30 to provide input
... During the Apr 30 call we will decide on each proposal

MC: what if there is disagreement on the 30th

AB: a decision will be made on all of these by the 30th, if not earlier

MC: David, can we get any feedback from BONDI on the L10N model?

DR: there hasn't been any discussion to this yet
... when do you need feedback?

AB: April 30 is the deadline
... Marcos, can you provide a short description of B1 and B2?

MC: B1 proposes the UA's locale can be a list of locales
... B2 proposes the UA just have a single locale
... HTTP supports multiple languages
... The basic question is: does the UA support one lang or a list of languages?

AB: any comments on B1 vs B2?

AS: so one use case is about knowing which langs a UA supports?

MC: yes

AS: I would expect the UA to have a single locale but a widget could be localized in many diff languages
... could then use prefs to manage this
... I can understand a UA support multiple locales but I'm not sure this is the best way to go about it

AB: yesterday I suggested we need some more reqs work and some more UC's to understand why need this stuff http://lists.w3.org/Archives/Public/public-webapps/2009AprJun/0269.html
... will you reply to my comments?

MC: I think you have some good comments
... we need to get this done as soon as possible

AB: yes, agree. But I also heard Andrew asking for some UCs too

AS: yes; some UCs and Reqs would be helpful in understanding the problems we are trying to solve

MC: some of the proposals do go beyond what current engines do today

AB: I get concerned about the complexity here for v1
... we seem to be moving from codifying the existing cow paths to building a new super highway
... Marcos, would you please give us a summary of the C* proposals?

MC: these about deriving te widget's locale
... diff between C1 and C2 is the order of searching for the widget's locale

AB: I hope that is clear to everyone; any questions?
... what about the D* proposals?

MC: these three proposals are about how to represent the widget's locale
... my preference is D2

AB: any comments or questions on these 3 D proposals?

[ Discussion between Andrew and Marcos about D2 and various scenarios ... ]

AB: can we get a short intro to E, F and G proposals?

MC: E proposals are about XML Base and whether we use XML Base itself or our own emulation of it

AB: I agree E1 seems reasonable to me

AS: does that apply to all URIs?

MC: yes

AS: OK; that's good

MC: F proposal addresses the "missing content" problem
... F1 uses root directory in search; F2 does not use root
... My preference is F1

AB: yes, F1 seems reasonable to me
... I think it works with the principle of least surprise
... please introduce G1 and G2 Marcos

MC: this is similar to F proposals but if the lookup is using URIs

Window Modes spec: status and plans

AB: Robin, what is your level of interest here?

RB: unless someone wants to lead this, I will start working on it next week

MC: we are interested and willing to collaborate on anyone that wants to lead it

AB: I think the plan is for Robin to start working on this spec next week and for MC to help
... is that right?

MC: yes

RB: yes

AB: meeting adjourned
