### Administrativia

<fjh> If you attended this year's TPAC meeting, the W3C created a related
survey for your feedback:
[http://www.w3.org/2002/09/wbs/35125/tpac2010-feedback/][17]

<fjh> 2011 1H publishing moratorium 13-18 May,
[http://lists.w3.org/Archives/Member/member-device-apis/2010Nov/0006.html][18]

fjh: there is a survey for getting feedback about TPAC

### Minutes approval

<fjh> [http://lists.w3.org/Archives/Public/public-device-
apis/2010Nov/att-0047/minutes-2010-11-04.html][19]

<fjh> [http://lists.w3.org/Archives/Public/public-device-
apis/2010Nov/att-0047/minutes-2010-11-05.html][20]

**RESOLUTION: The F2F minutes were approved**

### Media Capture API

<fjh> [http://lists.w3.org/Archives/Public/public-device-
apis/2010Nov/0048.html][21]

ilkka: sent a summary to the mailing list about the changes done

<fjh> [http://dev.w3.org/2009/dap/camera/Overview-API.html][22]

ilkka: the biggest change is about supported video/audio formats

<fjh> In a nutshell Capture API is not anymore using MediaFileData interface

<fjh> from HTML Media Capture spec as MediaFileData can't describe well

<fjh> available image, audio and video modes. To replace MediaFileData I added

<fjh> new ConfigurationData interface that currently contains height, width,

<fjh> and MIME type attributes.

<fjh> Additionally user of the API is now able to select one of the available

<fjh> image/audio/video modes while starting the capture process. Updated

<fjh> example illustrates this.

ilkka: users can select the supported mode for image/audio/video

... with the latest version of the spec.

... Another change is that former API used MediaFileData

... that was not very well suited for capture API, so I have added a separate
interface for that.

<Zakim> AnssiK, you wanted to ask about default mode

fjh: is it stable now, should we launch a CFC?

AnssiK: should we specify the default mode in case no mode is specified by
developer? or should it be decided by the implementors?

ilkka: currently no default mode concept, if the parameter is not present, the
behaviour is not specified.

... it may make sense to specify it.

AnssiK: How can I know the characteristics of a mode without launching the
capture method?

fjh: do we need any changes in the API to address AnssiK coments?

AnssiK: no changes required, happy as it is

fjh: suggestion, one extra week to review it and decide to go for CFC during
next call

ilkka: No rush to publish a new media capture API as it was published recently

### Sysinfo

<fjh> ACTION-294?

<trackbot> ACTION-294 -- Richard Tibbett to create an editors draft for new
proposed network connection API -- due 2010-11-11 -- OPEN

<trackbot> [http://www.w3.org/2009/dap/track/actions/294][23]

fjh: There was an action to create a new draft based on a new model (294)

richt: I will create a new proposal for this API, there is a lot of work to be
done

... an API only for network connection might be simpler

<fjh> general agreement that no consensus at this point

fjh: Need to wait for richt proposal

### Contacts

<dom> [http://dev.w3.org/2009/dap/contacts/Writer.html][24]

<dom> (also linked from DAP home page)

fjh: is there an editor's draft for contacts writing?

richt: I sent an e-mail with the info

... available at [http://dev.w3.org/2009/dap/contacts/Writer.html][24]

<dom> [http://lists.w3.org/Archives/Public/public-device-
apis/2010Nov/0002.html][25]

<richt> [http://lists.w3.org/Archives/Public/public-device-
apis/2010Nov/0027.html][26]

richt: the e-mail is available at: [http://lists.w3.org/Archives/Public
/public-device-apis/2010Nov/0027.html][26]

... this is for creating a Contact Blob Writer

... Now we have two competing ways to write contacts.

<richt> Contact Blob Writer spec is here:
[http://dev.w3.org/2009/dap/contacts/BlobWriter.html][27]

fjh: can somebody take an action to review it?

<dom> **ACTION:** Dom to review Contact Blob writer proposal
[http://dev.w3.org/2009/dap/contacts/BlobWriter.html][27] [recorded in
[http://www.w3.org/2010/11/17-dap-minutes.html#action01][28]]

<trackbot> Created ACTION-306 - Review Contact Blob writer proposal
[http://dev.w3.org/2009/dap/contacts/BlobWriter.html][27] [on Dominique
Hazaël-Massieux - due 2010-11-24].

dom: I can review the new API

richt: It would be good to stabilize the API and go soon for a Last Call

... and start working on test cases

<fjh> plan to publish updated WD of contacts api,
[http://dev.w3.org/2009/dap/contacts/Overview.html][29]

dom: what is preventing us from going to last call at this stage?

<dom> there are 5 open issues with Contacts API
[http://www.w3.org/2009/dap/track/products/5][30]

richt: The reader side at least is quite solid

dom: the only problem could be still having open issues on the API

<fjh> need to review issues related to contacts before last call

richt: I will review the open issues and send an e-mail

<fjh> **ACTION:** richt to send email to list with resolutions for open issues
against contacts, clarifying status [recorded in [http://www.w3.org/2010/11/17
-dap-minutes.html#action02][31]]

<trackbot> Created ACTION-307 - Send email to list with resolutions for open
issues against contacts, clarifying status [on Richard Tibbett - due
2010-11-24].

fjh: Can we do a CFC via e-mail or do we need to wait for next call?

... for the Last Call of the Contacts API.

... none of the chairs will be around next week, so it may be better to wait
for the following call

dom: I suggest to wait for the review of the open issues before deciding what
to do

<richt> dom, agreed

<fjh> next steps: rich to send closure of contacts issues, WG and chairs to
review and agree, then CfC for Last Call for Contacts API

### Messaging

<fjh> parameterization deferred, [http://lists.w3.org/Archives/Public/public-
device-apis/2010Nov/0052.html][32]

<dom> ACTION-302?

<trackbot> ACTION-302 -- Maria Angeles Oteo to morph Messaging API into an API
that wraps URI schemes options and adds attachment/success callback, and split
off subscription -- due 2010-11-12 -- OPEN

<trackbot> [http://www.w3.org/2009/dap/track/actions/302][33]

maoteo: I have distributed the proposal with the other editors

<fjh> maria- plan to publish update later this week

maoteo: could upload it to the CVS by end of this week

### Other APIs

fjh: Gallery, any update?

dom: have action related to use cases and requirements

### Security and Privacy

fjh: no concrete actions or updates at this point

### Interop and testing

<fjh> Information on WebApps/HTML5 javascript framework

fjh: Do we have something we should share with regards to the test framework?

<dom> [http://test.w3.org/resources/testharness.js][34]

<dom> [http://lists.w3.org/Archives/Public/public-html-testsuite/2010Nov/][35]

### Actions

[http://www.w3.org/2005/06/tracker/users/my][37]

... where are we with regards to the Calendar discussions?

richt: we have an action to rewrite the calendar API, based in x-calendar

... it is quite a long specification

... I cannot dedicate all the time it needs

<richt> If someone else would like to work on the Calendar API, please step
forward!

fjh: No call next week

<richt> I will certainly continue to assist with optimisations that we have in
e.g. Contacts API (i.e. data minimization, etc).

fjh: next call will take place 1st December
