We started with introductions from Raj Tumulari (Openstream) and 
Paul Duffin (Volantis). Raj has worked with Dave before in the Voice 
Browser WG. Paul is replacing Rhys who has moved to another company.

Dave then took us through the draft agenda for the March face to 
face, see:

Keith won't be able to go to the face to face, but will provide 
materials on the DCCI work beforehand. The DCCI session is scheduled 
for 9:15 am on Tuesday March 4th. This corresponds to Monday March 
3rd at 7:15pm in Boston, so in principle Keith may be able to attend 
remotely via IRC and skype.

Raj asked Dave for further details on DISelect.

Rotan isn't allowed to fly due to his leg injury, but plans to be on 
IRC and will try to use skype to join the face to face as a remote 
participant. The session on the ontology and APIs is scheduled for 
Tuesday afternoon, which is early morning in Dublin (9 hours 
behind Seoul).

Rotan mentioned the DDWG work on aspects and Dave said that that 
will be added to the draft agenda. Jose will be leading the session 
on the ontology, and luckily is also a member of the DDWG.

Dave noted that Rich Schwerdtfeger says he is freeing up time to 
allow him to focus on helping the UWA WG with extending the delivery 
context to deal with personalization. Rich is a co-editor of the 
WAI-ARIA specification for hte WAI-PG WG.

Dave asked Paul about when Volantis will be able to provide us with 
access to the tools developed by Rhys to generation specs from 
Protege for the ontology. Jose would like to be able to use these 
tools prior to the face to face.

Rotan gave an overview of the DDWG's work on an API for access to 
device descriptions and its relationship to work on the delivery 
context ontology.

Dave noted Jose's interest in working towards a single API for 
device capabilities. Rotan agreed that there were rather too many 
APIs at present. Dave has an action to summarise them all for the 
Hypertext CG, and thinks that it may be appropriate to organize a 
workshop to bring all the stake holders together. The ontology 
provides a valuable basis for reaching a shared understanding of the 
underlying data models.

Stephane unfortunately won't be able to make the face to face and 
will provide a status report for CC/PP 2.0 for us to consider in his 
absence.

Kangchan has been working on use cases and terminology for device 
coordination. We should be able to use the face to face as an 
opportunity to review the topic and set priorities for further work.

Raj noted his interest in distributed applications, which the work 
on device coordination is intended to facilitate, e.g. through rich 
descriptions of device capabilities, and mechanisms for resource 
binding and the use of events to loosly couple application 
components. The work is intended to complement the MMI WG's work on 
MMI Architecture. Raj has only recently joined the UWA WG and won't 
be able to attend the March face to face. He agreed to submit his 
thoughts on distributed applications in advance of the meeting.

Kazuhiro Kitagawa has just joined the UWA WG, and is a familiar face 
from the Device Independence WG. Kaz is only able to attend the 
second day of the face to face (Thursday March 6th). He will give us 
an account of the current status of the work of the PUCC and hopes 
to move the PUCC work on rich descriptions of consumer devices along 
the W3C Recommendation track.

The next topic on the face to face agenda is layered architectures 
for user interfaces and support for end-to-end modeling. Dave and 
Jose are in the process of setting up a W3C Incubator Group to 
study standardization opportunities and this is likely to feed into 
the next Charter for the UWA WG.

Paul says that he is interested in end-to-end modeling of mobile 
applications as a basis for next generation adaptation solutions. 
We briefly discussed the notion of context affinity which Rotan 
defined as how closely a particular piece of a site/page/service is 
bound to a particular delivery context.

Rotan says that the DDWG plans to ask for a 2 month extension that 
will allow them to continue until July 2008 for a joint meeting with 
MWBP and a workshop. He says that there have been suggestions that 
the UWA WG be asked to take on the task on maintaining the API 
developed by the DDWG. Dave suggested that it should be possible to 
recharter the UWA WG early to deal with that.

[Dave notes that we may have some complications with the W3C Patent
Policy as a result, but that should not deter us from this path]

We finished with Rotan explaining his ideas for including provenance 
as part of the ontology that provides a means to track where the 
information was originated. Paul noted that UAProf is frequently 
inaccurate and often invalid (a word is provided where a number was 
expected). He supports the idea of provenance.
