[Enum] RE: COMMENTS on draft-ra-shin-enum-mobileweb-01.txt

["Tim Moss" <Tim at bango.com>]

I very much agree with Ray here.

It would definitely be a good idea to discuss this proposal with the
World Wide Web Consortium (W3C) Mobile Web Initiative (MWI) as they are
putting significant resource into this area, in particular there are
three W3C working groups that should be contacted.

These are the Device Independence Working Group (DIWG), the MWI Best
Practices Working Group (BPWG) and the Device Description Working Group
(DDWG).

I don't believe that ENUM is necessarily the right place for storing
general device capabilities.  A single phone number could be used by
multiple devices (e.g. if the internet connection is initiated over
Bluetooth to a mobile device) with varying capabilities, or the same
device may have multiple 'browser' clients installed on it e.g. WML
browser, IMODE browser, video player etc.

However, ENUM could be a good place for a user to describe their
particular preferences with respect to how they would like content to be
presented to them, and potentially override any automatic content
adaptation that may otherwise occur.

This should definitely be worked out in detail with the MWI though
rather than splintering off into two (or more) different solutions for
achieving the same result.
