Re: [Simple] New I-D: presence data model and its relationship toourpresence work

[Alex Audu <alex.audu at alcatel.com>]

Hi  Jonathan,

The example with the "hospital rendering healing service" may not apply to our immediate
mandate,..but the point I was trying to make was that the  notion of a presentity could
could be applicable to a much broader case if it is realized that a presentity could
represent
a person, place or thing (sort of like a noun).  Now,  an object (both animate and
inanimate)
has a capability attribute. This is nothing more than the service the object can render.

So we have: A  Presentity contains the following attrributes:
  - characteristics (hard state info)
  - Status (dynamic/soft state info)  (including activciy, mood, location, etc)
  - Capability (service it can render)

I am just curious as to what effect, if any, this has on the ongoing debate about service
and
device.

Regards,
Alex.
