I2C and GPIO was presented in plenary 15:13:47 ... key takeaways - doing right thing and that there is interest 15:14:28 fjh: asking about timing 15:14:51 tobie: riju on holiday from 6 Dec to january, but has started working on the WebIDL now 15:15:22 ... expecting to have major part of that set before holiday, then work on implementation in Jan, goal of late Q1 15:16:00 ... should be able to get implementation experience 15:16:11 fjh: and your plans on issues, how does that fit? 15:16:24 tobie: either listen for change or get entire stream of data, two alternatives 15:16:31 ... ambient light is 1st 15:16:41 ... using threshholds 15:17:22 ... stream of data, device orientation would give us this, but no implementation in place right now 15:17:37 ... could be issue for defining spec 15:18:10 fjh: is fusion related 15:18:31 tobie: the more the fusion the more likely 1st case but still need to consider high performance cases 15:19:09 ... hard to split work 15:19:16 q? 15:19:57 fjh: would like to understand the changes to the spec and when we should publish again 15:20:20 tobie: thinking about what we can take out of spec , and will work soon on some clarifications 15:20:55 ... reading algorithm will be difficult without tackling device annotation 15:21:27 s/annotation/orientation/ 15:22:16 ... will continue on what can be done, noting issues that remain. Experience from Riju should help 15:22:54 ... can underspecify part of algorithm, let device orientation specify it, or have another level of the spec later once we have implementer feedback 15:24:50 gmandyam: device orientation could have LC based on some changes, so should be able to wrap up the spec, that should enable working on new version based on generic sensor API 15:27:19 fjh: any other ways people in group can help with this work 15:27:32 tobie: feedback on algorithms after I do update will be helpful 15:28:30 ... working to get this for Jan if I can, not sure of personal availability 15:28:39 fjh: are TAG members aware of this work, should we share with them 15:28:56 tobie: should send to TAG review 15:29:09 ... ok on security side, slightly concerned about privacy side 15:29:27 s/slightly// 15:29:43 ... API design aspect relates to TAG 15:30:01 fjh: probably early, wait for Jan revision with implementation experience 15:30:03 fjh: agree to reference fingerprinting spec 15:30:27 tobie: more like guidance 15:30:32 s/spec/document/ 15:30:48 fjh: can ask PING later for review 15:31:44 tobie: automotive concerned about timeline 15:31:55 mats has joined #dap 15:32:02 https://github.com/w3c/automotive/issues/72 15:32:33 ... they seem to have similar issues to Generic Sensor API, e.g frequency of sensor polling, what if asking for frequency higher than sensor can handle 15:32:51 ... will depend on maturity of our spec, other specs will have same problem 15:33:06 ... expect it to be similar for IoT group 15:34:15 ... timing may work out naturally, once other groups realize the issues are difficult 15:35:01 fjh: anything else useful to discuss today? 15:35:48 tobie: the spec will describe how to read data from a local sensor; how will Web of Things relate? 15:35:59 ... not sure how to handle at spec level 15:36:11 ... do we need subclass of Generic Sensor that is local sensor 15:36:46 fjh: good to create an issue; will depend on what Web of Things becomes, need to coordinate 15:36:55 tobie: looks like that might happen later 15:37:10 ... work right now is on protocol handshakes etc 15:37:55 ... concern is whether we should consider local and remote sensors the same way 15:38:30 fjh: could have generic sensor spec and a different spec on how to share over the network 15:42:09 fjh: would be good to avoid dependency and have a separate spec for remote access, would simplify etc 15:42:25 tobie: agree, should defer until we have a well-defined issue 15:43:02 fjh: automotive will have this issue 15:43:16 tobie: yes, but they aren't implementing that yet 15:43:35 Topic: Charter 15:44:21 dom: under W3C management review, have small set of pull requests, plan is to finalize management review, share pull requests with group then start formal AC review 15:45:27 Topic: other TPAC 15:46:04 dom: bluettooh and NFC likely to become WGs later this year, similarity to questions on privacy and security 15:47:45 s/bluettooh/bluetooth/ 15:47:56 Topic: Upcoming Meetings 15:48:15 fjh: Please note that next meeting is 3 Dec then after a holiday break we have meeting 7 January 15:48:25 fjh: see http://www.w3.org/2009/dap/minutes.html 15:48:30 Topic: Other Business 15:48:32 none 15:48:35 Topic: Adjoirn 15:48:46 s/Adjoirn/Adjourn/ 15:49:26 Present+ Giri_Mandyam 15:49:33 rrsagent, generate minutes 15:49:33 I have made the request to generate http://www.w3.org/2015/11/12-dap-minutes.html fjh 15:52:28 Regrets+ Mats_Wichmann 15:52:33 rrsagent, generate minutes 15:52:33 I have made the request to generate http://www.w3.org/2015/11/12-dap-minutes.html fjh
