### Editorial Updates

darobin: HTML Media Capture...what's the status?

... have there been updates?

<dom> [no recent update, still open issue with regard to combination of
attributeß]

darobin: action seems to be done.

<AnssiK> +1 for publishing it

darobin: go ahead and publish and ask for feedback?

<fjh> +1 to publish early and often, e.g. HTML Media capture, updated WD
(correction to agenda)

**RESOLUTION: Publish HTML Media Capture as an updated draft**

<darobin> **ACTION:** Robin to handle publication of HTML Media Capture WD
[recorded in [http://www.w3.org/2011/04/13-dap-minutes.html#action02][23]]

<trackbot> Created ACTION-383 - Handle publication of HTML Media Capture WD
[on Robin Berjon - due 2011-04-20].

darobin: Next item is Messaging API. Do we want to do CfC?

<dom> "decision, wait a week for feedback, then pubiish WD next week "

<dom> +1

darobin: no new feedback so again happy to publish

<dom> "This draft proposes a vastly different approach to the previously
published version, using URI schemes as a way to address different messaging
protocols instead of using separate methods. The group is specifically looking
for feedback on which approach is felt like the most useful."

<dom> it is

<dom> [http://dev.w3.org/2009/dap/messaging/][24]

fjh: note in document status to point to other version?

<fjh> thanks see it now

<darobin> **ACTION:** Robin to handle publication of Messaging WD [recorded in
[http://www.w3.org/2011/04/13-dap-minutes.html#action03][25]]

<trackbot> Created ACTION-384 - Handle publication of Messaging WD [on Robin
Berjon - due 2011-04-20].

**RESOLUTION: Publish updated draft of the Messaging API**

Next item is Status Events.

<fjh> Battery Status Event

<fjh> Agreed to publish FWPD after updates completed.

<fjh> updated, [http://lists.w3.org/Archives/Public/public-device-
apis/2011Apr/0051.html][26] (Anssi)

<fjh> additional, [http://lists.w3.org/Archives/Public/public-device-
apis/2011Apr/0066.html][27]

AnssiK: feedback has been included in the spec

... Tried to address those comments directly in the spec or noting issues
raised on the mailing list in the document.

<fjh> draft [http://dev.w3.org/2009/dap/system-info/battery-status.html][28]

<dom> [we would need to send a CfC for the FPWD of battery status; it should
probably highlight its relationship with SysInfo]

<darobin> **ACTION:** Robin to put out a CfC for Battery Event [recorded in
[http://www.w3.org/2011/04/13-dap-minutes.html#action04][29]]

<trackbot> Created ACTION-385 - Put out a CfC for Battery Event [on Robin
Berjon - due 2011-04-20].

**RESOLUTION: Put out a CfC for Battery Status Events**

Next up is Network Connection API.

<fjh> Network Connection

<fjh> CfC for FPWD after Suresh completes edits.

<fjh> update, [http://lists.w3.org/Archives/Public/public-device-
apis/2011Apr/0064.html][30] (Suresh)

darobin: not sure if Suresh has finished his edits?

<dom> "The only change that is pending is the "network change" event." "If
this works I can go ahead and incorporate it."

fjh: Suresh's email left us a little unsure of whether to publish now.

AnssiK: seems like a few properties got added. Concerned by mobile specific
attributes

+1 [too mobile specific in its attributes]

<dom> AnssiK, could you send your concerns as a reply to the list?

darobin: let's continue the discussion. would be good to get the draft in CVS.

<AnssiK> dom, will do

<fjh> +1 to putting draft in CVS

fjh: will put it in CVS

<dom> network-properties-api?

<dom> "network" is so generic

<dom> "network-life-and-everything"

fjh: network-connection URL prefix?

... done.

this is a no bikeshedding zone :)

Next up is Contacts API

<fjh> Editor action (Rich) to update search filters

darobin: action on richt to update section 5.2.2

<fjh> contact error interface, [http://lists.w3.org/Archives/Public/public-
device-apis/2011Apr/0040.html][31]

<dom> (contacts is our most advanced spec, it would be good to move it to LC
sooner rather than later)

richt: not yet done. not a priority to publish at this stage

<fjh> +1 to dom on moving to LC earlier rather than later

darobin: would be good if we could go to last call in early May (or something
along that timeframe)

<dom> (we had LC for Contacts Apr in our roadmap, so I guess this will need to
be delayed one more time...)

richt: will try to update this section so we can publish. proving difficult to
focus on this API right now since its not high priority in terms of
implementation just now.

darobin: more feedback to do with error interface

<darobin> [Contact error codes][31]

richt: have no strong opinions either way on the Contact error codes

darobin: find it slightly more convenient with strings. just wondering when
the error codes are used.

richt: perhaps we could define when the error codes are thrown in the rules
and algorithms of the spec.

darobin: it's an interop problem otherwise.

... will try to have a go at fixing this.

richt: no problem for me.

Next up is Calendar API

<dom> **ACTION:** Dom to ping PH re FPWD of calendar [recorded in
[http://www.w3.org/2011/04/13-dap-minutes.html#action05][32]]

<trackbot> Created ACTION-386 - Ping PH re FPWD of calendar [on Dominique
Hazaël-Massieux - due 2011-04-20].

darobin: made a request to publish the Calendar API. Have not heard back from
W3C management.

... we need permission to publish.

... as soon as that happens I'll do the pub request properly (pub rules)

Next item - SysInfo

darobin: perhaps difficult to discuss the proposed static properties without
Suresh around.

### Issue review

<darobin> ACTION-363?

<trackbot> ACTION-363 -- Dominique Hazaël-Massieux to see with Maria on how to
proceed for updated messaging api draft -- due 2011-04-06 -- PENDINGREVIEW

<trackbot> [http://www.w3.org/2009/dap/track/actions/363][33]

fjh: don't need to do much here. we've been through this recently.
