Welcome jo: welcome to John, and welcome back to Phil Archer phil: waves jo: phil was co-editor of the initial mobile web document phil: here mainly in my role as W3C team member, responsible for providing training around BPs 2. Update on MWABP (BP 2) adam: we've had a smallish amount of feedback, I have a long list of TODOs and haven't gotten around to updating the doc yet ... we need to conclude on CSS spriting and multipart ... and possibly something around a BP on AppCache, which is HTML5-specific - or at least technologies which involve ... not downloading an entire JS package when starting an app. Not sure how to make a BP out of it. <jo> ACTION-961? <trackbot> ACTION-961 -- Tom Hume to investiagate multipart-mixed in the context of 3.4.6 and 3.4.7 of MWABP -- due 2009-05-19 -- OPEN <trackbot> [15]http://www.w3.org/2005/MWI/BPWG/Group/track/actions/961 [15] http://www.w3.org/2005/MWI/BPWG/Group/track/actions/961 jo: starting with multipart... <Zakim> tomhume, you wanted to agree tomhume: did some research, doesn't appear broadly supported but generally agreed to be a good sort of thing jo: so shall we resolve as not suitable for a BP? <jo> PROPOSED RESOLUTION: Multipart is not boradly enough supported to be a mobile best practice chaals: say nothing, or explicitly reject it? jo: say nothing I think. chaals: agree <jo> PROPOSED RESOLUTION: Multipart is not broadly enough supported to be a mobile best practice - so do not reference it <jo> +1 +! +1 <adam> +1 <yeliz> +1 <DKA> +1 RESOLUTION: Multipart is not broadly enough supported to be a mobile best practice - so do not reference it adam: as a footnote... as part of Eduardo's discussion re spriting: it's broadly supported in a subset of mid/high-end subset devices. I'd say keep it in as they are. Is there support in the group for that? <jo> [16]Discussion on CSS Spriting [16] http://lists.w3.org/Archives/Public/public-bpwg/2009May/0032.html Discussion on Sprites for decoration only, thread starting at edC: the point is, spriting is supported but does it bring the benefit that it's supposed to bring? jo: what do we need to do to determine this one way or another? <jo> [17]Eduardo's Point on Spriting [17] http://lists.w3.org/Archives/Public/public-bpwg/2009Jun/0019.html edC: entice Stephanie (Rieger) to provide figures wrt latency with and without sprites adam: shall I take an action to follow up on this thread and follow up with her? jo: yup <jo> ACTION: Adam to follow up with Stephanie Rieger ref her comments and what the actual benefits are % terms [recorded in [18]http://www.w3.org/2009/06/09-bpwg-minutes.html#action01] <trackbot> Created ACTION-965 - Follow up with Stephanie Rieger ref her comments and what the actual benefits are % terms [on Adam Connors - due 2009-06-16]. adam: I've had some feedback, mainly internal, that AppCache is v v valuable to web applications (partic. mobile gmail). It feels odd to remain silent on it, although it is HTML5-specific - so a BP might generate complaints. But what do we think? dka: strongly agree that it's important, but is it too early to talk about it? My view is that it's in the same bucket as some of the stuff in the web apps working group - I would like to see something come out which details how to use AppCache and other offline-web-app techniques, but it seems separate from this document. <jo> ACTION-064? <trackbot> ACTION-64 -- Rittwik Jana to submit a text for section 6.2.5 on user preferences -- due 2005-09-27 -- CLOSED <trackbot> [19]http://www.w3.org/2005/MWI/BPWG/Group/track/actions/64 [19] http://www.w3.org/2005/MWI/BPWG/Group/track/actions/64 <jo> ACTION-964? <trackbot> ACTION-964 -- Tom Hume to review AtomDB for potential inclusion/reference in MWABP -- due 2009-06-09 -- OPEN <trackbot> [20]http://www.w3.org/2005/MWI/BPWG/Group/track/actions/964 [20] http://www.w3.org/2005/MWI/BPWG/Group/track/actions/964 jo: is there something in general to say about using offline where available? dka: yes, giving an example of appcache - though maybe not telling people to use it jo: adam, can you do a small BP around emerging offline techniques? <EdC> The tenor of the comments seems that appcache, atomdb, etc. are examples of offline application management. The BP should then be general. tomhume: will have atomdb looked at by next week <jo> ACTION: Adam to write a small BP on offline techniques citing AppCache as an example (and the outome of AtomDB as appropriate) [recorded in [21]http://www.w3.org/2009/06/09-bpwg-minutes.html#action02] <trackbot> Created ACTION-966 - Write a small BP on offline techniques citing AppCache as an example (and the outome of AtomDB as appropriate) [on Adam Connors - due 2009-06-16]. adam: I fwded some feedback to the member list earlier today, re large complex web apps on mid to high-end browsers... one limitation on fast startup is JS parse time. We have a BP around minimising latency, but the partitioning of large scripts might be more important according to some feedback we had. ... I don't feel we need to go into technical details re how to partition, but it is valid feedback - if you're about to write a web app and do it well, follow all BPs, you'll hit problems around parse time and JS. Splitting it up is the only way to build a good scalable web app. Given this should we pull it out into a BP? jo: why pull it into a separate BP if we've nothing specific to say about it? adam: to make it more prominent? jo: a BP without anything actionable is a problem adam: happy to leave as is right now, wanted to flag it as feedback I had... jo: maybe insert a note to call out this point and say it's been discussed? adam: feedback next week would be helpful... 3. Update on BP 1.5 jo: there was an editorial meeting to update some of it. I had actions to make further comments in the doc. Phil has stepped forward to act as an ongoing editor of the doc. Status now is that I've finished making comments to the google doc, we have an editors meeting tomorrow morning (open to anyone in the group)... <jo> [22]Current work in progress on BP 1.5 [22] http://docs.google.com/Doc?docid=d2vmqg3_0c469pzdh&hl=en phil: led into a false sense of security here, schmoozed and seduced by appelquist :) There's a bit more to do than I thought. Want to get it to the point where the group can take a look without a need for further protracted discussion - if it's contentious, it comes out, if it can be smoothed over, it stays in. Should put it to bed in the next 2-3 weeks. 3bis: MobileOK scheme <PhilA> [23]http://www.w3.org/2005/MWI/BPWG/Group/Drafts/mobileOK-Trustmark/ 20090609 [23] http://www.w3.org/2005/MWI/BPWG/Group/Drafts/mobileOK-Trustmark/20090609 <PhilA> [24]http://www.w3.org/2005/MWI/BPWG/Group/Drafts/mobileOK-Trustmark/ 20090610 [24] http://www.w3.org/2005/MWI/BPWG/Group/Drafts/mobileOK-Trustmark/20090610 <jo> -> Jo's comments on MobileOK Scheme and the license <jo> [25]Jo's comments on mobileOK Scheme and the License [25] http://lists.w3.org/Archives/Public/public-bpwg/2009Jun/0021.html phil: changes hats. I'm involved with MobileOK scheme thanks to my work with the POWDER protocol. When talking about POWDER I take off my W3C hat. This doc bears my Greek affiliation. We've been through it, the license is the issue... jo: with phils changes and Rigo making basic changes and clarifications to the license, we're done on it. ... we do need a correct copy of the license, despite the need for speed ... Can the group review it, make any comments this week, and we'll take a resolution next week. edC: can you remind everyone what the main issues pending last time were on mobileOK? jo: phil wanted to clarify the status on PNG phil: we were implying that you should have a PNG format trustmark, just after we recommended not having unnecessary icons on the screen... jo: anything else on mobileOK scheme? ... we can't take a resolution until we have a corrected final license. But we can action francois to ping Rigo. <jo> ACTION: Phila to ask Rigo to consider Jo's comments and revise mobileOK license accordingly [recorded in [26]http://www.w3.org/2009/06/09-bpwg-minutes.html#action03] <trackbot> Created ACTION-967 - Ask Rigo to consider Jo's comments and revise mobileOK license accordingly [on Phil Archer - due 2009-06-16]. 4. CT Draft 1r <jo> [27]CT Draft 1r note from Jo [27] http://lists.w3.org/Archives/Public/public-bpwg/2009Jun/0015.html <jo> ACTION-929? <trackbot> ACTION-929 -- Eduardo Casais to write an abstract for CT. -- due 2009-04-02 -- OPEN <trackbot> [28]http://www.w3.org/2005/MWI/BPWG/Group/track/actions/929 [28] http://www.w3.org/2005/MWI/BPWG/Group/track/actions/929 jo: first point is eduardo's action 929 <jo> [29]Jo's comments on EdC's Proposal [29] http://lists.w3.org/Archives/Public/public-bpwg/2009Jun/0018.html jo: eduardo was asked to put together an abstract.I agree with his points but think rewording would be of benefit. Are you happy with my rewording? edC: Yes jo: it's now a bit lengthy, but calls out some important points. <jo> PROPOSED RESOLUTION: Adopt text as proposed by EdC and amended by Jo for the Acbstract (cf ACTION-929) <jo> +1 <EdC> +1 <achuter> +1 <DKA> +1 RESOLUTION: Adopt text as proposed by EdC and amended by Jo for the Acbstract (cf ACTION-929) <yeliz> +1 jo: next point is much more contentious, francois' action-925 <jo> ACTION-925? <trackbot> ACTION-925 -- François Daoust to ascertain the availability of tests that ensure that same origin policy conformance, when implemented in this way, can be tested -- due 2009-04-02 -- OPEN <trackbot> [30]http://www.w3.org/2005/MWI/BPWG/Group/track/actions/925 [30] http://www.w3.org/2005/MWI/BPWG/Group/track/actions/925 jo: would rather do this with francois here, but let's talk about it now anyway, I doubt we'll resolve it in one go ... francois has determined that there are no existing conformance tests we can reference to show that same-origin niceties are observed by a transforming proxy when rewriting links ... The resolution we took was that in the absence of such tests we couldn't condone link-rewriting at all, never mind https. ... So if we stick to the previous resolution, we rewrite the doc to say "link rewriting is not acceptable", meaning all kinds of CT proxies cannot be conformant. <DKA> -1 to that chaals: i've been chatted to some of our security and testing guys. we think we could make a test for this. we possibly have one already, i couldn't find it... ... I've just found one! ... around cross-site scripting jo: and cookies? chaals: yep. The cookie thing is a consequence, right? jo: we wouldn't want passwords in cookies sent to the wrong site chaals: the security risk is cross-site scripting. with that you can get cookies out, or whatever. ... I'll find a test. jo: is this new technology or old technology? ... Any objections to adopting this normatively, should it pass all the tests we expect it to? chaals: Luca does. jo: he's not a member of this group, but we'll take his view into account. edC: I'd immediately put an action to someone on what the status of taking over tests from external parties is. Who will maintain these tests, etc? jo: interesting point. if charles submits it to a group in contribution, there's no IP impediment to the group in using it. ... on maintenance, isn't this in the normal run of maintenance of the document? I'm not sure it's a different question. chaals: the group has to agree this test is valid first of all. Subsequent to them agreeing, the group can go ahead and use it. jo: what does anyone feel about us verifying the test is adequate? edC: how do we do this? ... what do developers and contributors to it claim that it covers? chaals: The one I'm looking at right now covers the ability to do a cross-site request. jo: irrespective of this, how do we verify cookies are not sent between sites they shouldn't be sent between? ... given that you're using transcoder.mobi and a browser will think all cookies are for transcoder.mobi and not hte origin site, how do we ensure transcoder.mobi intercepts cookies correctly? chaals: that's not the test I have right now, but I'll find out jo: anyone else got comments? ... for link rewriting, we can put chaals' tests into the conformance requirements, if we agree with them, and we can move ahead. <DKA> +1 to this proposal. <SeanP> Seems reasonable to me. <jo> ACTION: Chaals to forward tests for Xss and cookie handling to group [recorded in [31]http://www.w3.org/2009/06/09-bpwg-minutes.html#action04] <trackbot> Could not create new action - please contact sysreq with the details of what happened. <trackbot> Could not create new action - please contact sysreq with the details of what happened. <jo> [from F2F and now at 4.2.9.3 of the CT doc:] <jo> Interception of HTTPS and the circumstances in which it might be permissible is not a "mobile" question, as such, but is highly pertinent to this document. The BPWG is aware that interception of HTTPS happens in many networks today. Interception of HTTPS is inherently problematic and may be unsafe. THe BPWG would like to refer to protocol based "two party consent" mechanisms, but such... <jo> ...mechanisms do not exist at the time of writing of this document. <jo> The practice of intercepting HTTPS links is strongly NOT RECOMMENDED. jo: next point is around https rewriting. we resolved this at the F2F to say (see above) ... it turns out RFC2119 doesn't contain the term "NOT RECOMMENDED" so we'll need to rewrite it ... the doc goes on to say what you must do if, nonetheless, you rewrite links. <jo> [32]HTTPS Link Rewriting [32] http://www.w3.org/2005/MWI/BPWG/Group/TaskForces/CT/editors-drafts/Guidelines/090607#sec-https-link-rewriting <jo> qck t <Zakim> tomhume, you wanted to wonder what NOT RECOMMENDED becomes jo: NOT RECOMMENDED would become SHOULD NOT <chaals> [would be "should not" as Jo says] seanP: rfc2119 contains "NOT RECOMMENDED" as a synonym for SHOULD NOT ... so no need to change. phil: copying and pasting stuff can trip you up... jo: so action is to add this to the keywords section of the document <jo> ACTION: Jo to add NOT RECOMMENDED to the rfc2119 section of the document [recorded in [33]http://www.w3.org/2009/06/09-bpwg-minutes.html#action05] <trackbot> Created ACTION-968 - Add NOT RECOMMENDED to the rfc2119 section of the document [on Jo Rabin - due 2009-06-16]. jo: if there's no further comment on this (and bearing in mind other comments from the list) let's move on ... can people kindly review that document, only been out 2 days. I'd like to propose a resolution for next week that we take it to last call a second time. ... it has a couple of dangling ends but not many. one of them is francois recreating the conformance statement, we also need to formally respond to the previous last call before we do a new one, but that's a technicality. ... comments? AOB and ISSUE and ACTION bashing jo: anyone? <francois> [I haven't seen the explicit list of new X-Device-<foo> HTTP headers in the doc, is it normal?] <jo> [yes, francois, I think I inserted text, per the resolution] <jo> [wel,, I *hope* so anyway] ACTIONS <jo> [34]http://www.w3.org/2005/MWI/BPWG/Group/track/actions/open [34] http://www.w3.org/2005/MWI/BPWG/Group/track/actions/open <francois> [ok, I'll have a closer look and will follow up on the mailing-list if needed] <jo> ACTION-694? dka: this one was overtaken by events. I think this one needs closing. <jo> close ACTION-694 <trackbot> Getting info on ACTION-694 failed - alert sysreq of a possible bug <jo> ACTION-783? adam: suspect this is obsolete. i think we talked about web 2.0 technologies and decided the term was naff, but have long ago replaced it. <jo> close ACTION-783 <jo> ACTION-783? dka: ACTION-787 not done.
