Hi Robin, all,

Hi all,
here is a draft of the Intents joint Task Force charter for comments from
WebApps and Device APIs. A TF charter is nothing formal and requires no
overhead — it can live as an email in a mailing list, it just documents the
existence of the TF, and gives a few indications as to how it works.
I've added some notes below about the points that may be contentious. If no one
screams bloody murder by Monday I'll ask the Team to set things up. It's short
but we've discussed this together last week, and DAP intends (no pun, err,
intended) to rely rather heavily on Intents so we'd rather move fast rather
than wait for WebApps to recharter, which could take a few months.
"""
The Web Intents Task Force works on a joint deliverable of the WebApps and
Device APIs WGs that aims to produce a way for web applications to register
themselves as handlers for services, and for other web applications to interact
with these through simple requests brokered by the user agent (a system
commonly known as Intents, or Activities).
The mailing list on which the TF's discussions take place is
public-inte...@w3.org. The chair is Robin Berjon.
Operational modalities such as whether or not to have phone and/or face to face
meetings, as well as where to store the draft document are left to the TF to
decide for itself. Decisions are made by consensus inside of the task force and
do not require separate ratification by the wider groups.
It is important to note that until such a time as the WebApps WG is rechartered
with Intents in its list of deliverables, it will be necessary for participants
in WebApps who are not in Device APIs and wish to make substantive
contributions (just joining the discussion and providing comments is always
fine) to make an RF commitment for this deliverable (not necessarily for other
DAP deliverables, naturally). For more details on this, please contact the W3C
Team.

ISSUES:
• The description isn't terribly precise, but I think it works
• As I've said before, I am only putting myself forward as chair because so
far no one else stepped up. I don't mind doing it, but I equally don't mind
letting someone else do it. I don't expect it to be a very demanding position.
WDYT?
Opera would like to explore Local Device and Local Network Discovery as
a subset of Web Intents. At this point, having studied the Web Intents
proposal, we're unclear how this would work considering that:
a.) to register a URL endpoint as an intent provider the user must visit
a web page (presumably hosted by the target device itself) and capture
the intent registration from that page before that intent provider can
be used within the UA.
>> WHAT WE ACTUALLY WANT: to enable auto-discovery and
auto-registration of local device services and locally networked device
services to the point that the user doesn't need to go out and register
local devices and services upfront. When a user requests a particular
service, they can then directly choose a device that implements the
requested service rather than having to go through the indirection of
searching out, navigating to and registering each intent provider first.
b.) to then subsequently use a registered intent provider the concept is
to open that provider, again as a web page in a seperate tab within the
UA. From here we can then establish a bi-directional web messaging
channel on which we can send and receive messages to communicate to and
from that web page that is representing the current local service.
>> WHAT WE ACTUALLY WANT: to communicate transparently with a
locally-connected service (after user authorization has been
established), without requiring that service to manifest itself as a web
page in a new browser tab. We'd also like to speak the protocol (web
sockets, http, etc) that the device currently supports.
My assumptions on Web Intents above may be incorrect. I'd appreciate
some clarification if this is the case.
Perhaps someone could take the time to describe exactly how a user could
communicate with an existing TV device in their home from a web browser
supporting web intents based on the above requirements?
