at this time we don't have a polycom reserved for the F2F according to

<dom> I don't know if it is still time to ask for that additional  
equipment ó
susan's message isn't explicit about that

<tlr> I wonder whether we could solve this by using skype with a nice

<fhirsch> [http://lists.w3.org/Archives/Public/public-device-

Paddy: discussion kicked off on how features are identified

<fhirsch> [http://lists.w3.org/Archives/Public/public-device-

<marengo_> my connection dropped

<marengo_> sorry

<fhirsch> paddy: feature is ability to use capability for a specific api

<tlr> issue-28?

<trackbot> ISSUE-28 -- [Policy] Requirement for NO security prompting --

<trackbot> [http://www.w3.org/2009/dap/track/issues/28][25]

paddy: brief discussion last week

<fhirsch> [http://lists.w3.org/Archives/Public/public-device-

<dom> [Paddy's summary on ISSUE-28][26]

paddy: tried to pull out the things which everybody agree

<dom> (linked to ACTION-28 - which I think can now be closed)

paddy: seems clear that the requirement isn't going away

... modal prompts are bad and avoidable with good api design

... user should know something is happening

... many questions have been raised on the ML

... One was about asking just once

... and giving fine grained decision support later

fhirsch: suggests to create issues related to such discussion

<fhirsch> **ACTION:** paddy to enter issues based on issue-28  
[recorded in

<trackbot> Created ACTION-29 - Enter issues based on issue-28 [on  
Paddy Byers
- due 2009-10-28].

<Bryan> +1

resolution: paddy to start creating a draft Policy Requirements document
related to issue-28

complete additional details at

marcin: we are talking about protecting apis

complete additional details at
[http://www.w3.org/2009/dap/track/issues/34/edit][32] .

<fhirsch> issue-34: [http://lists.w3.org/Archives/Public/public-device-

<trackbot> ISSUE-34 Protecting data versus protecting apis notes added

marcin: in dap we try to create apis for mananing contacts, events, ...

... protecting the apis is not security

<fhirsch> isn't this a discussion of granularity of access control?

marcin: as a refinement of protecting apis we can go further and  
specify which
parameters are valid or not

<fhirsch> Bryan: BONDI can define security sensitive parameters, e.g.  
access to file location

marcin: will clarify this in BONDI

fhirsch: will it work with things like Contacts

<fhirsch> filtering with tag based rules, e.g only sms to contact

Information and Events API.][39]

<dom> (that seems to be an awful long document - I would rather see  

<AnssiK> +1 for making the spec modular and weeding out parts which  
should go
to v1

dom: suggests to keep only the things we are going to implement

<fhirsch> dom suggests may want to limit scope of the system info to  
cpu etc
but not compass and sensors

<fhirsch> dom notes compass is important API but not as a system API

what is
feasible for v1

<fhirsch> need to consider implications of amount and scope of work,  

<fhirsch> all - Please review document and comment on list, which  
should be in
system API, what should be in v2, and what should be a separate API

AnssiK: (there's a discussion on the ML in the recent mails)

... multi-tasking use cases are considered

idleness/visibility of the browser context which is likely somewhat  
to us as well: [http://lists.w3.org/Archives/Public/public-
webapps/2009OctDec/0223.html][47] )
