Minutes for April 21 Backplane telecon

The minutes for the April 21 Backplane telecon are at:
http://www.w3.org/2009/04/21-backplane-minutes.html

Expanding a bit, topics covered were:

1. review of the way in which structural changes were being made between
two lists in the Finance scenario.  We decided to replace the general list
transformation (which did not require fixed categories for expenses)
implemented in script with a set of binds (that are specific to given
categories) in order to keep all of the data transformations within model
processing.  It's a known requirement for XForms 2.0 to support structural
transformations in addition to value computations so this allows us to more
clearly show the role of model processing vs. needing to call out to a
value-change listener in the UI and then trigger script code.

2. we discussed addition of more SVG custom controls to show the pattern of
expense amounts over time.  This work will take place over the next week or
two.

3. we brainstormed briefly the role of SMIL in the scenario and await
further inputs from Jack on this point.  In general, the demo
implementation would be ready to start using some SMIL Ubiquity
implementation within a few weeks...

Thanks, Charlie
