Mapping

I've just written a new tutorial, describing how to write an XForms application that overlays data from a BBC Backstage feed onto a Google Map. The application is pretty short and straightforward, but it also provides a cogent illustration of the advantages that the XForms model can bring, even to non-XForms user interfaces.

The XForms model is a powerful component which provides declarative syntax for defining data, actions and submission requests. This tutorial demonstrates how to use some of that power to drive the Google Maps JavaScript library with data from a UK public transport information feed; although any other feed that contains map co-ordinates in the data could be used instead.
