Very soon, I'll be heading off to the W3C Technical Plenary.
Sure, it's in Cannes, but it's also in February, so it's all business.
This is a time when many W3C working groups congregate in order to have time to have intergroup meeting times. So, the XForms working group will have its face-to-face meeting later in the week, but so will a dozen or more other groups. Similarly, the compound document format group chaired by Kevin Kelly will meet earlier in the week. I plan to sit in on some of that as an observer and to talk as needed about the intersection of XForms and compound document formats.
The mid-day of the plenary is a time for common presentations, one of which is a panel presentation called "Rich Web Application Backplane". Kevin is the chair of the panel, which has a number of panelists including yours truly.
The panel is basically about the notion that we have lots of rich XML processing capabilities available now, expressed as XML. This allows for compound documents that are capable of aggregating the data, views, rich user experience, and web services needed to complete a sophisticated web application transaction.
While some further work can be done to do a better job of creating more seamless integration of various components in the W3C stack, a lot of the foundational technologies are already there and in pretty good shape, so herewith is the rallying call to pull them together into an XML backplane capable of supporting the design of rich web applications.
One of the things I really like is the potential for XML events to be the glue that binds together nicely modularized XML technologies into an effective, intelligent compound document. I think an update to XML events would be useful to add certain key features, but even as-is the capture and bubble phases combined with event context have allowed me to express an integration of XML signatures into a compound document format that includes XForms and a first class presentation language (XFDL, of course).
Of course, whenever we talk about advancing the conceptual model of the web in some way, we get a certain amount of feedback about whether we are talking about evolutionary change or revolutionary change. The latter causes IT folks ot go weak in the knees over deployment issues, so branding something revolutionary is really about trying to stop it from happening.
This means that you can have a staged migration to a rich native client that directly runs the high level language because the conceptual model expressed by the language can be delivered, with few limitations, to today's client platforms-- zero footprint.
In the IBM Workplace Forms space, we call the native client "Viewer" and we call the zero-footprint version "WebForm Server". The idea is that you design an XFDL form containing precision presentation, rich user experience and business logic/dynamic interactive capabilities using XForms within the XFDL. Then, you deliver it using one of these two interactive rendition engines.
A demo of this capability is how my panel segment will end. After all, nothing trumps being able to show some of the kinds of capabilities that would be enabled by the rich web application architecture.
