Hello everyone, We have recently produced an XForms application that overlays data from a BBC public transport information feed onto a Google Map of the UK. The application actually came about as the subject of a tutorial [1] that we were writing for our developer site. However, we think it is worth sharing with a wider audence since it demonstrates very clearly the suitability of the XForms model for driving this type of application. The application also represents a good starting point for anyone else considering using XForms in this area, because it can be very easily amended to utilise any feed that contains latitude/longitude data (both tpegML and RSS).
One of the main benefits that XForms brings to the application is its clean separation between the model and the view. In fact, in this case, the view contains no XForms UI controls at all, as that is handled by Google Maps. The XForms model provides a concise, declarative syntax with which to define the feed request, the form actions and the data store. To enable the application to run free-standing on your desktop, it targets our Sidewinder Viewer [2] software and our formsPlayer XForms processor [3]; these are both available as free downloads from our developer site. Once you have these installed, the application can be run by navigating to it in your browser; it is available in our public SVN repository [4]. We've also uploaded a screenshot [5] of the running application to flickr, in case anyone would like to take a look. Regards, Phil.
