RESOLUTION: Minutes from 27 March 2014 are approved

HTML Media Capture

proposal to change Security & Privacy considerations to non-normative.

http://lists.w3.org/Archives/Public/public-device-apis/2014May/0008.html (Frederick)

<scribe> ACTION: fjh to send CfC to update HTML Media Capture with proposal for security/privacy consideration, 1 week CfC [recorded in http://www.w3.org/2014/05/15-dap-minutes.html#action01]

<trackbot> Created ACTION-689 - Send cfc to update html media capture with proposal for security/privacy consideration, 1 week cfc [on Frederick Hirsch - due 2014-05-22].

Minor battery update to make security/privacy section non-normative (done)

http://lists.w3.org/Archives/Public/public-device-apis/2014May/0009.html

fjh: did not address Network Service DIscovery security/privacy regarding non-normative, anticipate other priorities for that work

Network Service Discovery

fjh: posted summary of some thoughts about NSD direction http://lists.w3.org/Archives/Public/public-device-apis/2014May/0021.html

One case is Web & TV, we need detail on the actual use cases and requirements: http://lists.w3.org/Archives/Public/public-device-apis/2014May/0019.html

Another discussion is pushing content to local network devices as simpler than pulling, see http://lists.w3.org/Archives/Public/public-device-apis/2014Apr/0027.html

Mark Vickers notes that abstraction is used for window.print and also 2nd screen cases ( http://lists.w3.org/Archives/Public/public-device-apis/2014Apr/0025.html )

richt: if we find a simpler approach might get away for existing devices and services
... working on named web sockets, can get bidirectional connections, very simple

… advertisement and discovery is simple , does not use UPnP

… however we also want UPnP and zeroconf

cathy: agree we need to go back to use cases and define problem

… need to get broader discussion

fjh: we might want to reconsider the very high implementation bar, which targets a very specific community of browser implementers

… yet might want adoption earlier via browser extensions etc

… should consider Jean Claude implementation but possibly premature before we review use cases

http://lists.w3.org/Archives/Public/public-device-apis/2014Apr/2014Apr/0033.html

fjh: did we every reply to Youenn, http://lists.w3.org/Archives/Public/public-device-apis/2014Apr/0022.html

… a reply is warrented

<scribe> ACTION: fjh to reply to Youenn re use cases etc [recorded in http://www.w3.org/2014/05/15-dap-minutes.html#action02]

<trackbot> Created ACTION-690 - Reply to youenn re use cases etc [on Frederick Hirsch - due 2014-05-22].

fjh: issues list is all about network service discovery

http://services.w3.org/xslt?xslfile=http://www.w3.org/2009/dap/issues.xsl&xmlfile=http://www.w3.org/2009/dap/track/issues/open%3fsort=id&recurse_auth=on&content-type=&submit=transform

fjh: a number of issues such as search by device type might be resolved by use case reveiw
... one of these is fixed for promises

close ISSUE-158

<trackbot> Closed ISSUE-158.

fjh: please all work on documenting and discussing use cases on list

<richt> Original requirements: http://www.w3.org/TR/hnreq/

richt: we should revisit this as well

Testing

fjh: following webapps approach to testing
... we need wg volunteers to review and approve pull requests

cathy: ok for me

anssik: ok as well

fjh: how do we, for HTML media capture, close or change the pull request

anssik: can close them or ask submitter to change

fjh: going with the change is best

cathy: dom can do anything, close etc

anssik: web test model not documented but assumes git

fjh: anssik do you have any next steps

ACTION-523?

<trackbot> ACTION-523 -- Anssi Kostiainen to Work on test cases for battery, vibration, and HTML Media Capture -- due 2012-08-31 -- OPEN

<trackbot> http://www.w3.org/2009/dap/track/actions/523

anssik: working on implementations, e.g. ambient light, so should have additional implementation on chromium, can move interop on that spec forward

for battery google/chromium may want some changes to this spec, so may need to defer testing

… mozilla has confirmed

… ok with change, need to update test suite, then publish another LC, CR is 2 years old

<scribe> ACTION: fjh to make CfC to update Battery and do another LC per suggested changes from google [recorded in http://www.w3.org/2014/05/15-dap-minutes.html#action03]

<trackbot> Created ACTION-691 - Make cfc to update battery and do another lc per suggested changes from google [on Frederick Hirsch - due 2014-05-22].

fjh: do we have a proposal on the list

anssik: we have one, but it is not complete

<anssik> ok to send a CfC for proposed changes to the spec

<anssik> then, land changes to the spec, assuming no concerns

<anssik> pub LC, then another CR + update the test suite

anssik: get more implementer feedback on ambient light, another implementation will be Chromium

… vibration - we have 2 implementations, chrome/Firefox so could pass interop now with complete test suite

… need to check test suite for completeness

… html media capture, have 2 implementations, landed in WebKit, not sure shipping in product , has been in Chrome for a year

<anssik> https://www.w3.org/2009/dap/wiki/ImplementationStatus

… updated implementation status wiki to reflect on this

<mats> tizen has some form of media capture (webkit based), fwiw

… for battery there is proposed change + need to get Chromium implementation to complete interop

html media capture - need security/privacy change, have two implementations

ambient light - have one implementation, chromium implementation almost done, so should have interop completed soon

anssik: firefox implemented device light events, exposing lux value. Light level event exposes human readable range

… thus only part implemented

… chromium also only implemented device light events

… question of whether to remove light level event interface, might drop from spec, if so have two implementations and test suite from marcos

fjh: don't remember who brought that feature in, but does not seem to have support

<scribe> ACTION: fjh to send CfC to remove light level event from ambient light, return to LC [recorded in http://www.w3.org/2014/05/15-dap-minutes.html#action04]

<trackbot> Created ACTION-692 - Send cfc to remove light level event from ambient light, return to lc [on Frederick Hirsch - due 2014-05-22].

anssik: browser vendors prefer to have single interface

… reason for two was to avoid more events

… sending CfC ok now, since that feature is behind a flag and can still work on interop in parallel

proximity - feature in firefox, chromium intent to implement but not much progress, concern over use cases

anssik: idea was that you can effectivly obtain proximity using ambient light API

vibration - in both chromium and firefox, minor change to spec, so firefox implementation will need an update (or confirmation that it is up to date)

<scribe> ACTION: fjh to send message to confirm firefox status and plans to update for vibration [recorded in http://www.w3.org/2014/05/15-dap-minutes.html#action05]

<trackbot> Created ACTION-693 - Send message to confirm firefox status and plans to update for vibration [on Frederick Hirsch - due 2014-05-22].

<Cathy> Thanks anssik for the excellent summary!

<anssik> http://status.modern.ie/

anssik: IE team is also interested in some of these specs

… ambient light and battery status

… also vibration

<scribe> ACTION: fjh to check on how to communicate with IE team re DAP and feedback and ask about their plans if any to join DAP [recorded in http://www.w3.org/2014/05/15-dap-minutes.html#action06]

<trackbot> Created ACTION-694 - Check on how to communicate with ie team re dap and feedback and ask about their plans if any to join dap [on Frederick Hirsch - due 2014-05-22].

Microsoft is member of DAP

close ACTION-694

<trackbot> Closed ACTION-694.

<scribe> ACTION: fjh to check with Microsoft DAP members regarding plans for implementation and interop participation [recorded in http://www.w3.org/2014/05/15-dap-minutes.html#action07]

<trackbot> Created ACTION-695 - Check with microsoft dap members regarding plans for implementation and interop participation [on Frederick Hirsch - due 2014-05-22].

Thanks Anssi for overview and work on testing/interop

cathy: submitted some comment on html media capture pull request

… are you continuing to improve test suite

anssik: should talk to Zhiqiang Zhang

… in github or with direct mail cc'ing list

Tracking Preference Expression LC request for comments

http://lists.w3.org/Archives/Public/public-device-apis/2014May/0007.html

fjh: volunteers requested for review of this specification

Other business

LisaDeLuca_IBM: Web and Mobile Interest Group have been talking about Cordova alignment

anssik: I looked at gaps, Cordova implemented early versions

LisaDeLuca_IBM: we need specific details of what needs to be changed, then can expect developers to edit

anssik: can diff WebIDL

… can also start with test suite, to see what fails

fjh: if people want to help should they check out the interest group

lisa: or send email to me

Next call 29 May, in two weeks
