I have gotten feedback that maybe we do not need this session since it could be part of Bluetooth LE CG etc ... my response is that although that is relevant it is too low level to go straight to protocol, need to better understand application, requirements and higher level which is what this session is for dom: agree ; could invite Bluetooth CG to present to get that input but also valuable to understand higher level issues and needs ... for example privacy ... what other platforms do in this space, such as Apple Healthkit ... agree bluetooth is part of the solution but too eearly to say if entire solution ... need more info, should set expectations in advance. **ACTION:** fjh to follow up on inviting Bluetooth CG presentation at breakout [recorded in [http://www.w3.org/2014/10/02-dap- minutes.html#action02][24]] Created ACTION-722 - Follow up on inviting bluetooth cg presentation at breakout [on Frederick Hirsch - due 2014-10-09]. fjh: are breakouts an hour dom: yes see also Trust and Permissions in the Open Web Platform breakout also Next Steps for the Web of Things looks interesting TPAC registration deadline 8 October 2014, [http://www.w3.org/2014/11/TPAC/][25] ### Privacy Workshop on Privacy and User-Centric Controls Call for Participation "W3C Workshop on Privacy and User–Centric Controls" [http://lists.w3.org/Archives/Public/public-device-apis/2014Sep/0091.html][26] fjh: this is relevant to what we have done in DAP, will be relevant and useful to see what the latest thinking is, maybe some useful approaches ... anssik, do you know anyone that would be interested in submitting a position paper and/or participating in this privacy workshop? ### Battery fjh: Cordova Update, other updates? ... Lisa not on call so will continue fjh, we've informed our internal people fjh: anssik, thanks ### HTML Media Capture Follow up on test case errors, and appropriate contacts for Firefox and Chromium: [http://www.w3.org/2009/dap/wiki/ImplementationStatus][27] Are more tests required to covert Cathy Chan's comments? (I believe this has been done and implementation page can be updated, please confirm) [https://github.com/w3c/web-platform-tests/pull/306#issuecomment-39578557][28] fjh: anssik, do you have any update on HTML Media Capture, do you know correct contacts? I sent email to Mounir and Raphael da Costa fjh, I replied to the thread with information fjh: anssik, I must have missed that email, will check fjh, there's a patch that should be landed in Q4 that will fix the issue fjh, the test failures are due to the fact that Chrome/Blink is not fully WebIDL spec conformant yet, specifically, "DOM attributes should be moved to prototype chains and should expose JavaScript getters/setters". patch to fix that [http://crbug.com/43394][29] anssik, when will that patch be implemented and how will we know fjh, the owner says in the bug that he'll try to get that landed in Q4 if you look at the bug, it's been open for 4 years now it is a rather complex and intrusive change, must poke V8 here and there the update from the owner 6 days ago: "I'm working on this when I have a cycle (and aiming at completing it by the end of Q4)." fjh: sounds to me that this means we cannot complete HTML Media Capture this year, the tests will not be complete this year dom: right, tests will not complete this year, could progress document, if we agree to reduce WebIDL dependency fjh, FWIW, this is a generic idlharness.js blocker dom: however if we truly think this WebIDL issue will be addressed this year then can wait anssik, do you have a degree of confidence on whether this will truly be addressed this year ... or better, a bug in Chromium that means all the tests using idlharness.js will show red for similar tests dom: some groups have avoided limitation by demoting WebIDL dependency but then we need to go back to LC fjh, I trust in the owner's judgement that he can land this also Web Components folks want this fix landed increasing the probability that will happen dom: can decide to use WebIDL only for syntax not semantics, e.g. like geolocation fjh: anssik, thanks, so it sounds we can have confidence in patch landing this year, so no need to start workaround just try a random test suite in Chrome from w-p-t and it will show red for similar reasons fjh: if we delay a bit and go forward early next year that should work dom: sounds good to me cathy: two parts to comment, first part closed ... second part, verifying that when you have capture, that if user decides no, that you have no file ... not sure this part tested **ACTION:** zhiqiang to add test for user denial of captured file leading to no capture [recorded in [http://www.w3.org/2014/10/02-dap- minutes.html#action03][30]] Created ACTION-723 - Add test for user denial of captured file leading to no capture [on Zhiqiang Zhang - due 2014-10-09]. anssik, Please note I also gave action to zhiqiang re cathy potential additional test needed ### Ambient Light Events fjh: believe we are waiting for proposal from Rick. Anything else to add? anssik, have you been in contact with Rick about this? the redesign is a major thing, takes time I'd like to get the right people together to work on it, having Rick in the group is a great start fjh: right, interested to know if it is in progress, however ... good to know if work has started and who is involved. ### Vibration API Reminder, CfC Vibration API test report correct and complete; respond by 7 October [http://lists.w3.org/Archives/Public/public-device-apis/2014Sep/0074.html][31] ### Chartering fjh: Update or discussion? ... not sure we need to discuss ACTION-712?
