<Steven> hi

<Charlie> hi steven!

<Steven> I've been sitting in #rwab all afternoon :-)

<Charlie> agg

<Charlie> sorry

<Steven> even set up zakim and rrsagent

<Steven> No, my fault

<Charlie> well, it is inconsistent

<Charlie> can you stay on there too in case others go there?

<jsalvachua> Hello

<Charlie> hi there...welcome

<Steven> hi

41# raise your hand

Description of topics from Amsterdam level setting meeting.

jsalvachua = Joachim Salvachua

<jsalvachua> salvachua :)

Everyone has read the background material

Deliverables discussion

Not producing rec track documents

<Steven> From minutes:

<Steven> Task forces (with proposed champions, some not yet confirmed):

<Steven> Submission (Klotz, Hofn, McGlashan, Birbeck(?))

<Steven> Model (McGlashan, Jansen, Wiecha, Boyer(?))

<Steven> Eventing (Hofn, Pemberton)

<Steven> Access (Lewis)

<Steven> Intent-based events (Lewis)

<Steven> Navigation (Kelly(?))

We are adopting the new patent policy

Flexibility on what constitutes the report at the end

Originally Charlie was thinking about a document, but an executable implementation would be more compelling

An open source activity taking the backplane ideas in a lightweight Ajax implementation (Ubiquity Excellence) could be leveraged

Could be a wiki and report. Work interactively with an executable delivery.

Gregory: Agrees with Charlie's proposal for examples and working implementation

John: bottom-up concrete example would manufacture need rather than just spec work

Charlie: a spec would look very top down and architecture driven

<Steven> It's a bold approach

<Steven> I hope we can achieve it

Charlie: show benefit by doing something that runs

Steven: bold approach, a year is a short time to get an implementation though. Incubator group idea is to create something a working group can work on.
... is it more work than writing down what to do?

Gregory: objections and impracticalities could be cut out by doing this work

Charlie: Ubiquity Excellence code is a jump start for us to implement some of the Amsterdam report topics
... allows us to work in parallel on topics

<John_Boyer> Currently is "Ubiquity XForms" at http://code.google.com/p/ubiquity-xforms/

Kevin: agrees and cites CDF example

Greogry: agrees and cites an Aria example

Gregory: parallel activity on implementation made a stronger spec

Charlie: tutorial by expressive disclosure
... where would we host implementation

<oedipus> FYI: http://www.w3.org/TR/wai-aria (latest public draft) - http://www.w3.org/WAI/PF/aria/ (latest editor's draft)

John: agrees, code can be used by developers as a jumpstart

Charlie: a blending of open source and standards
... there should be a W3C hosted wiki presence

<Charlie> http://www.w3.org/MarkUp/Forms/wiki/XForms_Future_Features

Charlie: explains modularization that the Forms Group is doing

Gregory: example if the backplane can be specified then something like accessibility can be implemented easier

<oedipus> event flow and event cascade is addressed in ARIA ("politeness levels" amongst others)

John: pure XML events play event flow and the possibility for context info in events is a pretty cool delcarative way at the runtime level to do this
... XForms integration example with events and bubble phase exposure of content info exposed through modularization

<oedipus> very strong support for xforms submission module and providing information about bubbling and events to assistive tech via standard syntax (ARIA intended for repair, WAI prefers native solutions over overlays

Charlie: eventing infrastructure can be a way for components to signal each other
... performance of and granularity of events should be addressed

<oedipus> FYI: working for Open A11y on "Expert Handlers" for specialized knowledge markup (CellML, MusicXML, etc.) to communicate with assistive technologies in the context of the content being handled (music, cellular structure, etc.) to provide I/O capability for assistive tech without the assistive tech having to be aware of every XML dialect

John: it might uncover better ways to do events in other specs and provide a better generalized integration/bridging/eventing model

Charlie: wrap this discussion, perhaps a continued discussion on the mail list can occur

Logistics

Charlie: what frequency for things do we want?
... if we want to meet weekly we need to find another timeslot
... do we want to meet weekly? what would be better time?
... 10am or 11am slot probably best

MIT (Eastern US) time

Charlie: proposes 11am US Eastern Thursday

Steven: conflict with RDFA call, Wed also is a clash

Charlie: proposes 11am US Eastern Teusday
... any opposition?

<Steven> Me

<John_Boyer> +1

no opposition

Charlie: should we meet next Teus

Group: yes

Charlie: I will schedule it
