Re: Vehicle Location Information

For our discussion tomorrow and at the face to face, regarding new APIs, for those suggesting a new API, please come prepared with very specific arguments and examples.  Ideally you will ultimately have the following:

  *   paper laying out use cases and one or more of the following:
     *   recommended changes to existing W3C spec and why
     *   recommended changes to the vehicle information spec and why
     *   recommended new api for our group and why it is needed given other W3C APIs

Adam, Philipp, Kaz, Bernard, and Alan, et al.

Please let us know if I have missed anything and any other details those suggesting new APIs need to consider.  Your thoughts would be much appreciated.

I guess vehicle.acceleration (4.9.18) is in the same case,  there is very probably already this API somewhere in W3C APIs.
Concerning vehicle.temperature, as we consider inside vehicle and outside vehicle, I guess we can keep them as fully vehicle oriented.
All other vehicle interface are, for me, fully vehicle oriented.
To be discussed tomorrow or next week.
Best regards

Hi Kevron and other contributors to this topic,
Definitely, Apps developers want to use a unique API to get geolocation and, of course, current w3c geolocation API is the good one. And then I agree on the fact that OEMs (or third parties) have to provide the low level framework needed to choose between the native sensor and the added sensor (provided by the vehicle)...
But now the question is the same for the vehicle speed API, do we use the one provided by the standard w3c geolocation API (position.coords.speed) or do we need a specific one ?

On principle, I think I would have to say no, we don't need a specific
one if vehicle.vehicleSpeed and position.coords.speed are identical.

I propose we add something like the following section to the spec:

Relationship with other W3C APIs

Other W3C APIs can be used to supplement the Vehicle Information API.
It is assumed that in a vehicle implementation, these other APIs will
provide vehicle attributes.  For example, vehicle speed and location
information is provided by the Geolocation API.  [other examples?].
It is also assumed that these APIs will be implemented using data from
the vehicle.
