RE: Rechartering Device APIs & Policy Working Group


Generally I think that the charter looks good. To me it sounds logical to separate out work on a policy framework from DAP. It is architecturally independent of the APIs and requires another kind of competence than work on APIs.

Another question is the WG's view on "a generic sensor API" that is stated as "Future Work" in the current charter. Some options for sensors are for example:

* Consider it enough with the sensor APIs defined in the System Information API, Adding new, vendor specific, sensors is done through the extensibility method in

* Create something more generic. See for example

* Build a sensor discovery/selection mechanism / API on top of Web Introducer,


DAP has so far concentrated on "easy to use" "hardwired" APIs but the number of sensors, actuators, "things" located in the device, in the proximity of the device or anywhere in the cloud that web applications want to access is increasing. Is this something DAP should address or is this a task for another WG? 

So what do you think? 


P.S. Sorry for not responding to Robin's question on my Web Introducer prototyping at the last DAP call. Actually I did answer but I was on mute, which I didn't discover until it was too late :-) Anyway, I think that my mail talks for itself:
