### Generic Sensor API

follow up - [http://lists.w3.org/Archives/Public/public-device-
apis/2014Nov/0018.html][23]

fjh: a number of issues on github for follow up

[https://github.com/w3c/sensors][24]

fjh: follow up needed re Tim Volodine and Boris Smus joining WG?

... presumably they need to initiate request to join

... defer discussion for when we have participants, take to list

### Cordova Update

fjh: Lisa not on call. fjh: defer.

### Charter renewal

fjh: is this just happening

dom: have requested 1 year extension

... we previously discussed rechartering, but with no new work recently,
extensibiiltiy mechanism not needed in short term

... simplest to extend current charter

... prefer to avoid full rechartering unless needed

fjh: is extension approved

dom: director reviews and approved, plan for review and approval next week

fjh: we will get a notice

dom: yes

fjh: expectation for new work?

dom: nothing firm but possibilities

### Wake lock API

[http://w3c.github.io/wake-lock/][25]

see also use cases document [http://w3c-webmob.github.io/wake-lock-use-
cases/][26]

gmandyam: what is permissions model

... cannot expose across 3rd parties

dom: model is that by default that all can do, but notification to user that
screen is being locked

... model is ask for forgiveness model

gmandyam: do not like this model

... web sites can dramatically impact power consumption

dom: any app can do this today, via javascript

... timely for you to disagree, but there has been a discussion

gmandyam: not sure we've agreed to bring work into the group

dom: discussed, agreed we do not need to recharter

... if and when we recharter we would add explicitly to charter, but agreed to
interpret charter to include this work item

... if you disagree then we need to know so we can got throught the
rechartering process

gmandyam: we only have one browser committed to this

dom: two

gmandyam: will check on technical concerns regarding power consumption

dom: levels of disagreement: charter, useful for web, specifics of proposal

... need to be clear on which level of disagreement

gmandyam: are we going to progress the work or not, will got with it being in
the charter and having implementer support

... need explicit decision to adopt editors draft

dom: push to FPWD would explicitly resolve decisions about progressing,
considering in charter and enable call for exclusion

gmandyam: no decsions yet

dom: we have decision to get proposal in shape to enable FPWD decision

fjh: notes that FPWD triggers IPR obligations hence concern about scope, so
want to know what will be in FPWD

gmandyam: would like to see dated version

dom: would want CfC for FPWD noting frozen version

fjh: how long a CfC suffices

gmandyam: a month is enough

... no need to revisit charter concerns, so now only concerned about CfC and
FPWD

fjh: will ask editors if draft in github is FPWD material

<scribe> **ACTION:** fjh to check with wake lock editors on stability and
suitability for FPWD on wake lock api [recorded in
